Pillar comparison guide · Published by I.C.T · For SMT process, production and project engineers
Buyers comparing Hanwha placement equipment almost always arrive at the same fork in the road: the SM series, the platform that made Samsung-descended mounters a global standard, and the DECAN series, the next-generation family that now carries the flagship role. Both place components on PCBs with the same basic physics — multi-spindle heads, vision correction, tape and tray feeders — yet they answer different production questions, and the wrong fork costs either capability you needed or capital you did not. This guide works through that fork dimension by dimension, using the models stocked and supported in the SMT pick and place machine portfolio as the reference points.
The comparison is organized around the six questions that actually decide the purchase for the Hanwha SM series vs DECAN series: speed and the architecture that produces it, component range from micro chips to long connectors, flexibility and changeover behavior, dual-lane options and floor footprint, the application roadmaps each series fits best, and the cost and upgrade picture that closes the decision. Each section compares the two platforms on one dimension with real specification ranges, and the guide closes with an upgrade-path table and a decision checklist you can carry into a supplier meeting.

The SM series and the DECAN series are not two grades of the same machine; they are two generations of platform philosophy, and understanding what each represents prevents most selection confusion before it starts. The SM series — SM471Plus, SM481Plus, SM482Plus and the odd-form SM485 — descends directly from the Samsung mounter lineage that populated EMS floors worldwide for two decades. It is a platform defined by proven architecture, single-gantry simplicity in its mid-speed models, generous odd-form tolerance and one of the largest installed bases and spare-parts pools in the industry. The DECAN series — S1, S2, F2 and L2 — is Hanwha's next-generation answer: dual-gantry layouts in the speed models, updated vision and motion control, magnetic-leved drive technology at the flagship, and component capability that extends down to 03015 micro chips the SM platform never targeted.
That generational difference is exactly why the Hanwha SM series vs DECAN series question has no universal answer. A factory running mature, fixed-order boards on a budget values what the SM platform does best; a factory chasing micro-component density, higher takt and a long-term technology roadmap values what only the DECAN generation delivers. Hanwha itself has drawn the succession map — SM471Plus yields to DECAN S2, SM481Plus to DECAN S1, SM482Plus to DECAN L2 — which tells you the future platform, but not whether your next machine should be the future or the proven present. The sub-sections below define each platform on its own terms, map the official succession path, and explain why the older series remains a rational choice for a substantial share of productions.
The SM series spans four distinct personalities, and treating them as one machine is the first reading error to avoid. At the top, the SM471Plus is the speed model: two gantries of ten spindles each, a rated optimum of 78,000 CPH, and a chip-oriented component window from 0402 up to roughly 14 mm bodies — a high-volume chip placer in the classic Samsung mold. The SM481Plus trades to a single gantry of ten spindles at around 40,000 CPH but extends the component window dramatically: with its fixed-camera options it accepts large ICs up to approximately 42 mm standard and 55 mm in wide-field-of-view mode, plus connectors to about 75 mm, making it the series' general-purpose volume machine. The SM482Plus drops to six spindles and 30,000 CPH in exchange for the most forgiving odd-form envelope in the series — bodies to 55 mm and connectors reaching roughly 150 mm — plus PCB options stretching to 1,200 mm length for long boards.
The SM485 completes the picture as the insertion specialist: a four-plus-one spindle layout whose extra axis drives a gripper nozzle with force control, designed for pin-in-paste insert components, bare chips and irregular parts that ordinary placement heads handle poorly. Across the range, the platform constants are the ones that made the series famous — a 120-feeder standard capacity, the same docking-cart ecosystem, and an architecture whose spares, training and operator familiarity are available in every manufacturing region. That consistency is a selection asset in itself: a factory that already runs SM machines absorbs an additional unit with nearly zero relearning, and the secondary market keeps acquisition alternatives open that newer platforms cannot match.
The DECAN series reorganized the same placement physics around a faster, more precise generation of hardware. The DECAN S2 sits at the top with two gantries of ten spindles and a rated optimum around 92,000 CPH, driven by an updated motion system and a modular track design that can be reconfigured on site for different PCB widths — a maintenance and changeover benefit the SM architecture does not offer. Component capability reaches down to 03015 chips with accuracy in the ±28 micron class for chips and ±25 microns for ICs, a full generation beyond the SM series' 0402 floor and ±30-to-40-micron band, and it holds that precision at placement heights and body sizes up to roughly 42 mm with connectors near 75 mm. The DECAN F2 carries the same dual-gantry, dual-ten-spindle layout at around 80,000 CPH as the value-positioned speed model, keeping the 03015 floor and a component window that reaches approximately 55 mm odd-form bodies.
Below the speed pair, the DECAN L2 repositions the multi-functional role for the new generation: two gantries of six spindles, around 56,000 CPH, wide-body and long-component support with LED-optimized vision, and board options up to roughly 1,200 mm for lighting and display-format products. The DECAN S1 anchors the entry tier with a single gantry of ten spindles near 47,000 CPH, bringing the new platform's vision system and micro-chip capability into budgets the dual-gantry models exceed. Across the range, the platform constants are software and connectivity: the updated recipe management, vision correction and line-data integration that position DECAN as the long-term strategic platform — and that justify its succession role in Hanwha's own roadmap.
Hanwha has been explicit about how the two platforms relate, and the mapping is worth memorizing because it encodes the company's own judgment about which capabilities succeeded which. The high-speed chip role of the SM471Plus passes to the DECAN S2; the general-purpose volume role of the SM481Plus passes to the DECAN S1; and the multi-functional odd-form role of the SM482Plus passes to the DECAN L2. The SM485's insertion specialty has no single DECAN successor, which is itself informative: force-controlled insertion remains a niche the new platform serves through the L2's wide-body capability rather than a dedicated head. For a buyer, the succession table doubles as a capability crosswalk — it tells you which DECAN model to demonstrate against the SM machine you already know.
The succession is a phased transition, not a hard cutoff. SM-series machines in the field remain fully supported in the near term, spare parts for the huge installed base remain available through the secondary ecosystem, and production value in the existing fleet is real. But the direction is unambiguous, and it has planning consequences: lead times for specific SM variants, long-horizon spare-parts economics, and software-roadmap alignment all favor the newer platform as years pass. The table below summarizes the mapping; section seven turns it into an upgrade-planning tool.
SM series model | Rated optimum | DECAN successor | What changed in the successor |
|---|---|---|---|
SM471Plus (2 gantries × 10) | ~78,000 CPH | DECAN S2 | ~92,000 CPH, 03015 floor, ±25–28 µm class, modular track |
SM481Plus (1 × 10) | ~40,000 CPH | DECAN S1 | ~47,000 CPH, updated vision, micro-chip capable |
SM482Plus (1 × 6) | ~30,000 CPH | DECAN L2 | ~56,000 CPH, dual gantry, LED-optimized multi-function |
SM485 (4+1, force control) | ~22,000 CPH | — (L2 covers wide-body) | Insertion specialty remains SM-exclusive |
A rational buyer might ask why the older platform belongs on any shortlist once its successor exists, and the answer is that succession changes roadmaps, not the physics of your order book. If your boards are mature, your components sit comfortably inside the SM window — 0402 chips and upward, bodies to 42 or 55 mm, connectors the SM482Plus takes to 150 mm — then the DECAN generation's advantages at the micro-chip end buy you nothing you will use, while the SM platform's mature support network, operator familiarity and secondary-market depth translate directly into lower five-year cost. Thousands of production lines still run SM machines as their daily workhorses precisely because stability over a decade of fixed-order output is worth more to them than a specification ceiling they never touch.
The SM series also remains the pragmatic answer in several structural situations: budget-constrained capacity expansions where a quality used SM481Plus delivers volume at a fraction of new-platform cost; factories standardized on SM tooling, programs and feeder stock where an additional unit preserves fleet commonality; and odd-form-heavy products whose insert components fit the SM485's force-controlled head better than anything in the DECAN range. The disciplined selection posture is therefore not "new versus old" but "which capability window does my BOM actually occupy" — the question the next five sections quantify dimension by dimension, ending in the upgrade logic and checklist that turn the comparison into a signed decision.
Speed is the most quoted and most misunderstood dimension of the comparison, because headline CPH numbers mix two different architectural levers: how many spindles a gantry carries and how many gantries the machine flies in coordination. The SM series spans both levers across its range — the dual-gantry SM471Plus at the top, single-gantry machines below it — while the DECAN series concentrates its speed models in the dual-gantry class and lets its single-gantry S1 anchor the entry tier. Reading the two families' speed structure correctly means separating rated figures from architecture, and architecture from what your takt actually requires. The comparison that follows treats the rated numbers as ceilings, exactly as a disciplined buyer should.
Three sub-sections organize the dimension. First, how the SM series builds its speed range from 22,000 to 78,000 CPH and what each rung of that ladder is for. Second, how the DECAN generation raises the ceiling to roughly 92,000 CPH and what hardware makes the difference. Third, how to read both families' ratings honestly — because the standardized measurement behind the numbers, and the gap between optimum and real output, apply to every machine in this comparison regardless of badge.
The SM series' speed ladder is a study in matching architecture to order profile. The SM471Plus flies two ten-spindle gantries in coordinated opposition, so pick and place cycles overlap between heads, and its rated optimum of roughly 78,000 CPH made it the high-volume chip engine of the Samsung-descended lineup — the machine that consumer-board lines standardized on for years. One rung down, the SM481Plus retires to a single ten-spindle gantry at around 40,000 CPH, accepting roughly half the headline rate in exchange for a much wider component window with its fixed-camera options; it is the volume machine for boards that mix chips with larger ICs rather than pure chip fields. The SM482Plus drops to six spindles and about 30,000 CPH deliberately, because its job is odd-form tolerance and long boards, not takt records, and the SM485's four-plus-one layout at 22,000 CPH exists for insertion work where cycle time is irrelevant next to placement force control.
The practical reading of this ladder is that the SM series covers mid-to-high volume with one flag: only the SM471Plus is a genuine high-speed machine, and only the SM471Plus offers the dual-lane option that multiplies small-board throughput. A factory whose takt demands sit above what a single SM481Plus delivers has historically answered by pairing machines rather than buying a faster single unit — a workable answer, but one that doubles feeder stock, floor space and maintenance points. That structural ceiling is precisely the gap the DECAN generation was engineered to close, and it is the honest starting point for the speed comparison that follows.
The DECAN series attacks speed at the architecture level rather than the model level. Its two speed models both fly dual gantries of ten spindles: the flagship reaches a rated optimum near 92,000 CPH, and the value-positioned sibling holds around 80,000 CPH — both comfortably above the SM471Plus, the fastest SM machine, while carrying wider component windows than it does. The gains come from more than spindle count: updated motion control and drive hardware move the heads faster between pick and place coordinates, the vision pipeline processes recognition in flight with less dwell, and at the flagship the modular track design keeps boards flowing with less transfer overhead between placement cycles. The DECAN S2 flagship placement machine page details that top-tier configuration for buyers whose takt sits at the market-set end of the spectrum.
The lower rungs of the DECAN ladder matter just as much to the comparison, because they redefine the mid-speed tier rather than leaving it to the SM series. The single-gantry S1 delivers around 47,000 CPH — above the SM481Plus it succeeds — with the new platform's vision system and micro-chip capability, while the dual-gantry L2's 56,000 CPH exceeds its SM482Plus predecessor by more than eighty percent despite retaining the multi-functional role. In other words, the DECAN generation shifted the whole speed-versus-capability frontier outward: at every role from entry to flagship, the successor is faster than the machine it replaces, and the largest relative gains sit exactly in the mid-volume tier where most factories actually operate. The DECAN F2 high-speed value mounter is the clearest expression of that shift for volume buyers.
Whichever family a buyer shortlists, the rated optimum is a measurement condition, not a production forecast — a point worth anchoring in the standardized method behind the numbers. Placement performance figures in this industry are reported under the discipline of the IPC-9850 standard, which defines how speed and accuracy are measured so that datasheets compare honestly; it makes figures trustworthy without making them predictive, because your boards are not the reference board. Real output discounts rated rate for head travel across scattered component coordinates, vision correction on the components that need it, tray pickups, panel handling and changeovers, and the discounts land hardest exactly where rated rates are highest.
The planning discipline that survives contact with production is to convert both platforms' ratings to the same currency before comparing: take the rated figure, apply a realistic efficiency factor for your board type — roughly 0.5 to 0.7 of rated for chip-dense boards, 0.3 to 0.5 for mixed boards — and compare the resulting boards-per-shift figures at your changeover frequency. Run that arithmetic and a pattern emerges that the datasheets alone never show: on simple, chip-heavy boards the SM471Plus and the DECAN speed pair converge in real output because both are architecture-limited by the same board geometry, while on complex mixed boards the DECAN generation's vision and motion advantages widen the gap back open. The rated table tells you what each machine can do; the factor table tells you what each machine will do on your product — and only the second number belongs in a capacity plan.
Model | Gantries × spindles | Rated optimum | Speed role |
|---|---|---|---|
SM485 | 1 × (4+1 force-controlled) | ~22,000 CPH | Insertion and odd-form specialist |
SM482Plus | 1 × 6 | ~30,000 CPH | Multi-functional, long boards |
SM481Plus | 1 × 10 | ~40,000 CPH | General-purpose volume |
SM471Plus | 2 × 10 | ~78,000 CPH | High-speed chip placement |
DECAN S1 | 1 × 10 | ~47,000 CPH | Entry flexible, new platform |
DECAN L2 | 2 × 6 | ~56,000 CPH | Multi-functional, LED-optimized |
DECAN F2 | 2 × 10 | ~80,000 CPH | High-speed value class |
DECAN S2 | 2 × 10 | ~92,000 CPH | Flagship speed |
If speed decides how fast you produce, component range decides what you can produce at all, and this is the dimension where the two platforms' philosophies separate most visibly. The DECAN generation was engineered around the miniaturization curve: its speed models place 03015 micro chips — a full package class below the SM series' 0402 floor — while holding accuracy figures roughly a generation tighter. The SM series, engineered a platform generation earlier, counters at the other end of the same spectrum: its fixed-camera options and the SM482Plus/SM485 layouts accept longer connectors, taller bodies and force-controlled insertion work that the DECAN range does not replicate. The figure below shows the machines in their element, because component range is ultimately about what flows through the feeder bank.
The four sub-sections below split the component dimension into its real decision boundaries: where the DECAN series wins outright, where the SM series keeps capabilities its successor never inherited, how the vision architectures behind those windows differ, and how to compress your own BOM into the verdict. Buyers who work the dimension in this order almost always find that one platform drops away on two or three BOM lines alone — which is the point of doing the analysis before the demonstration instead of after it.
The clearest capability boundary between the platforms is the micro-chip floor. The DECAN speed models place 03015 packages — among the smallest chip components in volume electronics — while the SM series' windows begin at 0402 across the range, with the SM482Plus starting at 0603 for its standard flying-camera configuration. That single package class is not a rounding error: smartphone-class, wearable and high-density consumer boards specify 03015 passives exactly because board real estate demands it, and a factory whose roadmap includes such products has no SM-series path to them. The precision figures move together with the floor: the DECAN speed pair holds accuracy in the ±25 to ±28 micron class for chips and ICs, against the SM series' ±30-to-50-micron band depending on model and package, and at 03015 scale that difference is the difference between a working process and a yield investigation.
Fine-pitch IC behavior follows the same generational line. The DECAN vision pipeline's updated recognition and correction handles lead variation on dense packages with higher confidence, and the platform's motion control keeps flight-path dynamics tighter during the placement pulse — both of which matter more as pitch narrows. The honest caveat cuts the other way too: none of this matters for boards whose smallest package is 0402 or larger, which describes an enormous share of industrial, appliance and power-electronics production. The micro-chip end is therefore not a universal tiebreaker but a specific one — it decides immediately and irreversibly for factories on the miniaturization curve, and not at all for factories whose BOMs will never visit that neighborhood. Check your smallest specified package before reading another comparison dimension; it may settle the whole question in one line.
The component argument reverses at the large and irregular end, where the SM series retains capabilities the DECAN range never fully inherited. The SM482Plus accepts components to roughly 55 mm bodies in wide-field mode and — the figure that matters — connectors to approximately 150 mm in length, twice the roughly 75 mm connector reach of the DECAN speed models, with placement heights to 25 mm on its fixed camera. Above it, the SM485 remains unique in either family: its fourth-plus-one spindle layout drives a gripper nozzle with active force control, built for pin-in-paste insertion components, bare die and irregular parts where placement force must be managed rather than minimized. Products rich in terminal blocks, heavy connectors, transformers or through-hole-reformed parts still find their best automated answer in the SM platform, and that answer has no DECAN equivalent at any price.
This asymmetry is a deliberate platform decision rather than an oversight: Hanwha's succession mapping routes the SM482Plus's multi-functional role to the DECAN L2, whose wide-body and long-component support covers LED and large-format work, but the L2's window tops out below the SM482Plus's extreme connector reach and includes no force-controlled insertion axis. Factories whose odd-form content is structural — industrial controls, power products, automotive harness boards — should therefore read the succession table as partial at this end: the platform successor exists, but the capability envelope it inherits is narrower than what it replaces. Where those components dominate a BOM, the SM series is not the legacy option; it is the only option in the family, and the comparison ends there regardless of what the speed table says.
Beneath the component windows sit two different vision philosophies, and understanding them explains why each platform's window falls where it does. Flying vision — the camera riding the placement head, recognizing the component in motion between pick and place — is the speed architecture: the SM471Plus is built around it, and the DECAN speed models refine it with updated optics and processing. Flying recognition keeps chips and standard ICs flowing at full head speed, which is why the fast machines in both families lead with it; its constraint is optical field and lighting control, which caps the body sizes it can verify confidently. Fixed vision — a precision camera on the machine frame with dedicated lighting — trades cycle time for optical reach, which is why the SM481Plus and SM482Plus pair their flying camera with a fixed station for large bodies, tall components and connector leads.
The DECAN generation's answer to the same trade-off is a wider-field flying system plus software, extending what in-flight recognition can verify — the flagship verifies bodies to roughly 42 mm natively with wide-field options beyond — but the SM platform's fixed-camera stations still hold the edge at the extreme: 55 mm bodies, 150 mm connectors and the controlled-lighting recognition that insertion and reflective components demand. The selection translation is straightforward: chip-and-IC-dense boards live comfortably in flying vision on either platform, and the DECAN implementation does it faster; odd-form-heavy boards still benefit from the SM architecture's dedicated optical station. Between those poles, the demonstration — not the datasheet — should decide: bring your largest reflective component and your finest-pitch IC, and watch which architecture recognizes both without operator intervention.
The component dimension becomes decisive when it is tabulated against real BOMs rather than argued in the abstract. The exercise takes an hour: list every component class your products run, record the extreme case in each class — smallest package, finest pitch, largest body, longest connector, tallest part, any insertion component — and score each platform against the record. The table below is the reference frame for that scoring, compressing the two families' windows into the boundaries that actually decide purchases. Fill in your own extremes alongside it, and the verdict usually announces itself: one platform passes every row, or each platform fails a different row and the question becomes which failure is cheaper to work around.
Component dimension | SM series | DECAN series | Decides for |
|---|---|---|---|
Smallest chip | 0402 (0603 on SM482 std.) | 03015 (speed models) | DECAN — miniaturized consumer BOMs |
Placement accuracy | ±30–50 µm class | ±25–28 µm class | DECAN — fine-pitch, high-density |
Max body (standard) | ~42–55 mm (fix camera) | ~42–55 mm | Parity at common extremes |
Longest connector | ~150 mm (SM482Plus) | ~75 mm | SM — terminal-block-heavy boards |
Insertion / force control | SM485 gripper + force axis | Not offered | SM — pin-in-paste content |
Component height | to ~25–26 mm (fix) | to ~12–15 mm typical | SM — tall magnetics, modules |
Speed ratings are measured on good days; flexibility is what the machine delivers on every other day. In production, the dimension that separates platforms is how they absorb the schedule's friction — product changeovers, engineering changes, component substitutions, the mid-shift variation that no capacity plan survives intact. The SM series built its reputation here over two decades of field service, and its changeover behavior is thoroughly understood by every maintenance team that has run one. The DECAN generation redesigned that behavior around modern software: faster recipe recall, smarter vision correction and the modular track hardware that adjusts board width without mechanical rework. Which behavior fits depends less on the machines than on your order profile — how many products, how often, and how much engineering attention each changeover receives.
Three sub-sections work the dimension in order: how the SM platform behaves in high-mix service and why that behavior is so well understood; what the DECAN generation actually changed about changeover and correction; and how to match the two behaviors to your real order profile rather than to a marketing category. Buyers who quantify their changeover frequency before this comparison — products per week, changeovers per shift, engineering changes per month — will find one of the two sections below describes their factory almost exactly.
The SM series approaches changeovers the way a mature platform does: mechanically simple, procedurally documented, dependent on operator skill rather than software intelligence. Its feeder ecosystem — the standard 120-position capacity with docking carts — lets a prepared cart swap in a single motion, and because the same cart standard has shipped for two decades, the industry's accumulated practice around it is enormous: pre-staged carts, feeder kitting discipline, operator routines refined across thousands of lines. Program switching is conventional rather than fast, vision correction is solid on standard packages, and the platform expects its people to know the machine — which, across the SM fleet's enormous installed base, they generally do. For a factory whose changeovers are weekly rather than hourly, this is a completely adequate behavior profile at a lower acquisition price.
The platform's flexibility limits show at the extremes of mix. Vision correction on the older architecture handles standard packages confidently but is less assured on micro components and irregular reflectives; program switching carries more manual steps; and the architecture's fix-camera stations, which give the series its odd-form reach, add setup steps the flying-vision machines skip. None of these limits is hidden — every experienced SM user can recite them — and that transparency is itself an asset: the platform's behavior in your factory is predictable from day one, because someone in your organization, your region or your supplier's service team has already run your exact scenario on this hardware. Predictability is a form of flexibility, and for stable product portfolios it is the more valuable kind.
The DECAN series redesigned the friction points rather than the fundamentals, and the differences concentrate in software and motion. Recipe switching is faster and more complete — feeder maps, nozzle assignments and vision parameters recall as a unit — which converts multi-order days from a sequence of partial setups into a sequence of confirmed loads. The vision system corrects more aggressively: PCB deformation is compensated automatically, component offsets are re-taught from production data, and the recognition pipeline handles small and reflective packages with fewer operator interventions. At the flagship, the modular track hardware adjusts board-width configuration on site without mechanical rebuilds, turning what used to be a maintenance task into a setup parameter. The cumulative effect is that the machine absorbs more of the changeover itself and asks its people for less.
For high-mix operations, these changes compound. Each changeover saved minutes through faster recall; each engineering change costs less when the vision system re-corrects without a re-teaching session; each new product ramps quicker when micro-component recognition needs less manual assurance. The gains are largest exactly where SM behavior is weakest — micro packages, irregular parts, frequent switching — and smallest where the SM platform is already comfortable, namely stable products with standard packages running long campaigns. That asymmetry is the honest summary of the flexibility comparison: the DECAN generation is not universally more flexible, it is more flexible precisely at the friction points that high-mix factories feel hardest, and pricing that advantage requires knowing which side of the mix spectrum your order book sits on.
The match is decided by three numbers from your own production records, and the comparison collapses quickly once they are written down. First, changeover frequency: lines switching products multiple times per shift monetize the DECAN generation's recipe and correction advantages every day, while lines changing weekly run both platforms' changeover behavior well inside its comfort zone. Second, package frontier: order books that include 0402-and-below components, dense fine-pitch ICs or reflective odd-forms stress the older vision architecture disproportionately, because recognition confidence — not cycle time — sets the rework rate there. Third, engineering volatility: products that revise monthly benefit from the newer platform's lower cost of change, because every revision re-runs the correction pipeline the newer software automates.
Read those three numbers against the two platforms and a stable decision rule emerges. Stable products, standard packages, infrequent switching: the SM platform's predictability and price win, and the DECAN generation's advantages are paid for but rarely exercised. Volatile products, small packages, constant switching: the DECAN series' software advantages compound daily and justify their premium many times over. The uncomfortable middle — moderate mix, moderate volatility — is where the demonstration earns its keep: run your actual next-quarter products through both platforms' changeover sequences at production pace, time last-good-board to first-good-board on each, and let the measured minutes rather than the platform philosophy close the argument. Buyers who run that test rarely need the checklist at the end of this guide; the stopwatch decides for them.
Throughput questions eventually become layout questions: whether a line runs one board stream or two, how much floor the machines consume, and what the utilities and line length implications are. The dual-lane dimension is where the two platforms' hardware generations diverge visibly — the SM series offers it narrowly as an option on its speed model, while the DECAN generation builds modular track design into the platform itself. Footprint and utilities, by contrast, are closer to parity than buyers expect: the machines in this comparison share a physical size class almost exactly, and the meaningful differences sit in track flexibility and software-managed width change rather than in square meters. The figure below shows the line context these decisions land in.
Three sub-sections cover the dimension: which specific models in each family support dual-lane running and what the option actually delivers; the footprint and utility picture across both platforms; and how the choice interacts with line architecture — the inline-versus-modular decision that the mounter selection feeds into rather than concludes.
Dual-lane capability is narrowly and specifically distributed across the two families, and the details matter more than the marketing around them. On the SM side, the option belongs to the SM471Plus alone: its dual-lane configuration runs two boards of roughly 460 mm by 250 mm (610 mm length optional) in parallel, effectively doubling small-board throughput on the platform's fastest chip machine — a natural fit for compact consumer boards where two streams of the same product keep the head utilization high. The SM481Plus, SM482Plus and SM485 are single-lane machines; their throughput scaling comes from pairing units, not from track options, which is why high-volume SM lines historically grew as machine counts rather than lane counts.
The DECAN generation distributes dual-lane capability more broadly and pairs it with the platform's modular track design, which can be reconfigured on site for different board widths — so a DECAN line can run dual-lane on small boards today and convert to wide single-lane running as products change, without mechanical rebuild work. That reconfigurability is the substantive generational difference: the SM471Plus's dual-lane option is a fixed hardware configuration chosen at purchase, while the DECAN implementation treats lane structure as a setup decision. Factories with stable small-board products gain the same doubling from either approach; factories whose board mix shifts seasonally gain an option only the newer platform provides, and for them the dual-lane comparison is not about whether but about which kind of flexibility the lane structure should have.
The physical plant picture is closer to parity than any other dimension in this comparison, and buyers can plan floors almost identically for either platform. The SM-series machines measure approximately 1,650 mm in length by 1,680–1,690 mm in depth, with masses between roughly 1,575 and 1,730 kg; the DECAN models occupy the same envelope class, and both platforms' flagship configurations fit standard SMT line pitches without special accommodation. Utilities differ slightly more: the SM471Plus draws up to about 5.0 kVA against the mid-series models' 3.5 kVA, air consumption spans roughly 160 to 350 liters per minute across the range with vacuum-pump variants lower, and the DECAN machines sit in comparable bands. None of these figures changes a floor plan; all of them belong in the facility review that precedes one.
Two planning details deserve explicit attention despite the parity. First, feeder-cart clearance: both platforms' docking-cart changeover concept needs working space at the machine front that datasheet footprints omit, and lines that forget it pay in obstructed changeovers for the facility's entire life. Second, board-length extremes: the SM482Plus's optional 1,200 mm board support and the L2's long-board options both lengthen the effective conveyor envelope beyond the machine's frame, and the upstream and downstream equipment must match that envelope. These are the same reviews any mounter purchase requires — which is the practical point: switching between SM and DECAN does not change your facility conversation, it changes only the capability conversation inside the machines.
The mounter choice lands inside a larger line-design decision — whether the line runs as a straight inline flow or adopts modular segments — and the two platforms participate in that decision differently. Inline running is both platforms' native mode: same conveyor heights, the industry-standard handshaking that every neighboring machine speaks, and board flow that moves printer to placer to oven without buffering intelligence. The DECAN generation adds options at the modular end: its track modularity and software integration make it a natural core for reconfigurable cells, lines that re-balance between products, and the buffer-and-branch layouts that high-mix plants increasingly favor. The SM platform participates in modular lines too, but as a fixed-capacity node rather than a reconfigurable one — entirely workable, just less adaptive.
Buyers weighing the line-level question should read it in our comparison of inline and modular SMT line layout options, which treats the trade-offs line-wide; the mounter-specific summary is shorter. If the production model is stable inline flow — the majority of volume lines — both platforms integrate identically and the line architecture contributes nothing to the series decision. If the production model is modular, cell-based and adaptive, the DECAN platform's hardware reconfigurability and newer software integration align with that direction, and choosing the older platform inside a modular strategy means accepting fixed nodes in an otherwise adaptive design. The line and the mounter should agree on which decade's flexibility model they are built around; mixed messages there surface as integration cost during commissioning.
The dimension-by-dimension comparison collapses, in practice, into a shorter question: which platform matches your product roadmap. Factories do not buy specifications; they buy the next three to five years of their order book, and the honest way to run the Hanwha SM series vs DECAN series decision is to walk the major production archetypes and see where each platform is the natural answer. Consumer and automotive volume production points one way, LED and long-board production points another, industrial odd-form-heavy work points back toward the older platform, and a large share of real factories run mixed portfolios where the two series coexist deliberately. This section walks those archetypes with the specification logic from the previous sections attached, so the recommendation is traceable rather than asserted.
Four sub-sections cover the map: the volume archetypes where the DECAN generation is the clear answer; LED, lighting and long-board production where the multi-functional models concentrate; industrial and odd-form-heavy production where the SM series retains unique capability; and the mixed-fleet strategy of running both platforms side by side — the answer a surprising number of mature factories arrive at once the comparison is laid out honestly.
High-volume production with demanding takt and miniaturization pressure is the DECAN generation's home territory, and the reasoning assembles directly from the earlier sections. Consumer-class boards specify small packages and dense fine-pitch ICs that sit below the SM platform's component floor or uncomfortably inside its precision band; the takt the market sets demands dual-gantry throughput that only the DECAN speed pair delivers within a single machine; and product volatility — consumer boards revise constantly — monetizes the newer platform's recipe and correction software with every revision. Automotive electronics adds its own logic: production lives for years, traceability and process capability are audited continuously, and the DECAN platform's tighter accuracy class plus long-term software roadmap align with a product generation that will still be built a decade from now.
The concrete model choices follow volume. Takt-critical lines running dense small-package boards standardize on the flagship speed model; volume programs with more forgiving takt take the value-class F2 and bank the difference; capacity that grows in phases starts from the single-gantry S1 with a planned migration path. What the archetype does not favor is the SM series' strengths: its odd-form reach and insertion capability are idle on consumer boards, and its price advantage does not survive the yield arithmetic when the BOM specifies packages the older vision system handles marginally. For this archetype the succession is simply the decision — the newer platform exists precisely because this production profile demanded it.
Lighting and display production shifts the comparison onto board geometry rather than package size: long PCB formats, LED components with optical requirements, and driver circuitry full of connectors and electrolytic capacitors. Both platforms serve this archetype, but through different models and with different depth. On the SM side, the SM482Plus is the natural fit — its board options stretch to roughly 1,200 mm, its component window takes the large bodies and tall parts lighting boards carry, and its odd-form tolerance absorbs the connector variety without special tooling. On the DECAN side, the L2 was engineered for exactly this market: two gantries of six spindles at around 56,000 CPH, wide-body and long-component support, LED-optimized vision, and board options to roughly 1,200 mm, with the modular track hardware easing the width changes that mixed lighting products impose.
The decision inside this archetype comes down to LED intensity and speed. Products dominated by LED placement — strips, panels, luminaires with hundreds of emitters — benefit from the L2's lens-optimized recognition and its higher placement rate over the SM482Plus; dedicated LED lines also pair well with simpler dedicated machines, and our four-head Samsung LED pick and place machine is the reference point for that lighter configuration. Mixed products — lighting boards heavy on connectors and drivers, display modules with irregular parts — can tip either way, and the tiebreaker is usually connector reach: BOMs whose terminal blocks and connectors exceed the L2's roughly 75 mm window fall back to the SM482Plus's 150 mm capability. Lighting factories should therefore run the component-range table from section three against their driver BOMs before defaulting to the newer platform.
The industrial archetype — controllers, power supplies, instrumentation, harness-adjacent boards — is where the SM series remains not merely competitive but uniquely capable, for reasons the component table makes explicit. These BOMs carry the parts the DECAN range handles worst relative to the SM platform: terminal blocks and connectors beyond 75 mm that only the SM482Plus reaches at 150 mm, tall magnetics and electrolytics that exceed the newer platform's height window, and pin-in-paste or insertion components whose force-controlled placement is an SM485 exclusive in this families' universe. At the same time, industrial production rarely needs what the DECAN generation sells hardest: packages below 0402 are rare, takt is set by the scheduler rather than the market, and product stability means the newer platform's changeover software compounds slowly.
The economics follow the same logic. Industrial products run for years with stable programs, which is exactly the profile where the SM platform's lower acquisition cost, deep secondary market and familiar maintenance translate into the lowest five-year cost of ownership; section seven's cost analysis quantifies the shape of that advantage. High-mix industrial shops — the contract manufacturers serving many industrial customers rather than one — sit closer to the boundary, because their changeover frequency starts monetizing DECAN software advantages, and the disciplined answer for them is the stopwatch test from section four rather than an archetype default. But for the stable-product core of industrial production, the honest conclusion is that platform succession ran ahead of this market's needs: the SM series is not the legacy choice here, it is the correct one, and it will remain so for as long as industrial BOMs keep their connectors long and their packages conventional.
The archetype most large factories actually occupy is none of the above in isolation: a portfolio of products that splits cleanly between the platforms' strengths, and a fleet strategy that assigns each stream to the machine that fits it. This is not indecision — it is the correct reading of a comparison whose dimensions genuinely diverge. Volume consumer programs run on DECAN speed models where their micro packages and takt belong; industrial and odd-form-heavy products run on SM482Plus or SM485 machines whose windows and force control they require; LED lines take the L2 or a dedicated LED machine. The platforms share a feeder-cart philosophy, conveyor standards and line-integration conventions, so a mixed floor operates as one plant rather than two islands, and programs for a part common to both product streams live in the same software ecosystem.
The mixed strategy has planning requirements worth naming. Fleet-level spares stocking should segment by platform rather than assume commonality; operator training tracks two machine generations, which argues for stable line assignment rather than rotation; and capacity planning must respect that the two platforms' realistic rates differ even at equal rated figures, so board-to-machine allocation uses the per-product efficiency factors from section two rather than a single plant-wide number. Factories sizing a mixed floor against their space should also read our guide to SMT line configuration by factory size, which treats the layout arithmetic line-count by line-count. For portfolios that genuinely span the archetypes, the two-series answer is not a compromise — it is what the comparison was pointing toward all along.
Every dimension so far has compared capability; this one compares money, sequence and risk — the terms on which the decision is actually signed. The two platforms occupy different cost structures: the SM series prices lower new, depreciates through an enormous secondary market, and maintains through the industry's densest spares network; the DECAN series prices at next-generation levels, holds value through its roadmap position, and costs more to run in spares and training during its early market years. Neither structure is universally cheaper — five-year cost depends on how hard your production exercises each platform's distinctive capabilities. The sub-sections below work acquisition and running cost, then the upgrade path from SM to DECAN that existing SM users face, and finally compress the whole guide into the checklist that turns comparison into commitment.
A note on framing before the numbers: the succession table in section one showed that Hanwha's own roadmap runs SM to DECAN, which means every SM buyer is implicitly choosing a platform with a long-term horizon shorter than its successor's. That is not a reason to avoid the older platform — it is a reason to price the horizon explicitly. The sections that follow do exactly that, ending in the decision tool the previous six sections have been building toward.
Acquisition cost separates the platforms in both level and structure. New machines price in the obvious direction — the DECAN generation carries next-generation pricing at every tier, with the gap widest at the flagship and narrowest at the entry S1 — but the structural difference is the secondary market: two decades of SM-series production created a deep, liquid market in used and refurbished units, where an SM481Plus with verified hours delivers proven volume capability at a fraction of new-platform cost. No DECAN equivalent exists yet, and will not for years, which makes the secondary market not merely a discount channel but a distinct acquisition strategy for capacity expansions whose products sit inside the SM window. Budget-constrained projects should price both routes — new DECAN entry tier against quality used SM mid-series — because the capability comparison at those price points is genuinely interesting.
Running cost divides into spares, service and efficiency. Spares favor the SM platform today on availability and price — the installed base that created the secondary market also sustains the parts ecosystem — though the calculus shifts as DECAN volumes grow and SM production tapers, a horizon cost that long-horizon buyers should price rather than ignore. Service networks cover both platforms in every major manufacturing region, but SM expertise is more uniformly distributed across the technician population, which shows up in labor cost and response time outside major hubs. Efficiency — the section-two realistic-rate logic — is the DECAN platform's quiet running-cost argument: a machine that delivers more real boards per rated CPH produces each board for less machine-hour, and over five high-utilization years that productivity can outweigh a meaningful acquisition premium. The honest cost comparison therefore runs in a spreadsheet, not a price list: acquisition route, five-year spares, expected utilization, and the per-board machine cost that falls out of each.
Existing SM users face the comparison as a sequencing problem rather than a selection problem: not which platform, but when and how to add the successor without stranding value. The succession mapping gives the starting structure — SM471Plus capacity maps to DECAN S2, SM481Plus to DECAN S1, SM482Plus to DECAN L2 — and the first planning rule follows from it: upgrade the product stream, not the fleet. Identify which product family actually stresses the SM platform's limits — micro packages, takt, changeover load — and put the first DECAN machine on that stream, leaving the SM machines on the streams they serve well. This converts the upgrade from a fleet replacement project into a product-by-product migration, each step of which pays for itself on the specific pain that triggered it.
The second planning rule protects the investment already on the floor: sequence feeder and tooling decisions so value carries forward where it can. Feeder stock between the platforms is not fully interchangeable, which makes feeder purchasing during the transition years a deliberate decision — buy SM feeders for SM streams, DECAN feeders for the new machine, and avoid speculative commonality purchases in either direction. Programs and process data migrate more easily than hardware: component libraries, vision recipes and placement programs transfer with translation effort that the software ecosystem supports, and factories that budget for that migration — typically days per product family, not weeks — ramp the new platform faster. A disciplined project-first migration, structured exactly along the lines of our project-first Hanwha DECAN selection guide, turns the succession from a disruption into a scheduled capability rollout, one product stream at a time, with the SM fleet earning its keep until each stream's turn arrives.
The guide compresses to a one-page decision sequence, and running it in order takes an afternoon that prevents an expensive default. Start from the BOM extremes — smallest package, longest connector, any insertion content — because one row there can end the comparison before economics begins. Add the takt calculation in realistic-rate terms, the changeover frequency from production records, the dual-lane question if boards are small, and the product roadmap's five-year shape, since today's comfortable BOM can sit on the wrong side of the micro-chip line within a product generation. Score each platform per line, and let the failures — not the features — do the eliminating. The table below is that sequence in checklist form.
Decision line | What to record | If it points to SM | If it points to DECAN |
|---|---|---|---|
Smallest package | Smallest chip in any BOM | 0402 or larger across the roadmap | 03015 specified or planned |
Longest connector | Max connector length | Over ~75 mm (to ~150 mm) | All connectors within ~75 mm |
Insertion content | Pin-in-paste / forced parts | Present — SM485 territory | None in the portfolio |
Takt requirement | Realistic boards/shift needed | Within one single-gantry machine | Dual-gantry territory (80k+ class) |
Changeover load | Product switches per week | Low — stable campaigns | High — daily multi-product |
Board format | Dual-lane benefit, max length | Long boards (1,200 mm class) | Small boards, dual-stream gain |
Capital route | New vs used strategy | Used-market acquisition fits | New-platform roadmap value |
Run the checklist honestly and the decision usually resolves into one of three endings, each with a clear next action. One platform fails a hard line — a 03015 package or a 150 mm connector — and the comparison is over; demonstrate only the survivor, on your components, and negotiate. Both platforms pass everything and economics dominates; price the acquisition routes and five-year models and let the spreadsheet close it. Or the portfolio splits the platforms down the middle, in which case section six's mixed-fleet strategy is the answer and the real decision becomes sequencing — which stream converts first, and what the first machine visit should prove. All three endings share one discipline: the decision came from your production records, not from either platform's brochure, which is exactly where a placement purchase this consequential should come from.
Compare SM and DECAN configurations on your own products with I.C.T
Platform comparisons settle quickly once they meet a real BOM, and running that meeting is what our engineers do every week. Send us your component-range extremes, board outlines and changeover profile, and we will map them against the SM471Plus, SM481Plus, SM482Plus, SM485 and the DECAN S1, F2, S2 and L2 — returning a per-product recommendation with the realistic-rate calculation, the dual-lane assessment where boards are small, and an itemized quote for both new and quality-refurbished routes where the secondary market serves you. Whether the answer is one platform, the other, or a mixed fleet with a planned migration sequence, it arrives as evidence against your own production records rather than brochure arithmetic — the way a platform decision of this size should be made. Browse both families in the SMT pick and place machine portfolio, or share your BOM summary to schedule a demonstration on the components that matter most — your finest package and your longest connector, run side by side on the platforms you are choosing between.
No — the transition is a phased succession, not a cutoff. Hanwha has mapped each SM model to a DECAN successor (SM471Plus to S2, SM481Plus to S1, SM482Plus to L2), and the SM machines remain in service, supported, and available through new and secondary channels for the near term. The comparison in the Hanwha SM series vs DECAN series decision is therefore about fit, not availability: buy SM where its component window and cost structure fit, and buy DECAN where the roadmap, micro-chip floor and speed advantages matter.
The DECAN series holds the speed ceiling: its dual-gantry models reach rated optima around 80,000 to 92,000 CPH, above the SM471Plus's roughly 78,000, and even its single-gantry S1 exceeds the SM481Plus it succeeds. But rated CPH is a ceiling measured under standardized conditions, not a production forecast — real output depends on board geometry, component mix and changeover load. Convert both platforms to realistic boards-per-shift on your own BOM before accepting any speed verdict.
No, and this is the most consequential asymmetry in the comparison. The SM482Plus accepts connectors up to roughly 150 mm and tall bodies to about 25 mm on its fixed camera, and the SM485 adds force-controlled gripper placement for pin-in-paste and insertion components — none of which the DECAN range replicates. The DECAN L2 covers wide-body and LED work well, but BOMs with very long connectors or insertion content still require the SM platform regardless of the newer series' other advantages.
Let the package frontier decide. High-mix shops whose orders include small packages, dense fine-pitch ICs and frequent product switching benefit from the DECAN generation's faster recipe recall and stronger vision correction — those advantages compound with every changeover. Shops running conventional packages with moderate switching frequency run both platforms comfortably, and the SM platform's lower acquisition cost and deep service network usually win the five-year comparison. The stopwatch test — timing real changeovers on both platforms at production pace — settles the middle ground better than any specification.
Not fully, and feeder strategy deserves explicit planning during any transition between the platforms. Both use the same docking-cart changeover philosophy and similar feeder concepts, but feeder hardware is not freely interchangeable across platform generations, so factories running mixed fleets should assign feeder purchases to the platform that will consume them and avoid speculative commonality buys. Budget the migration of component libraries and placement programs separately — that transfer is software work, measured in days per product family.
Often yes, and for a specific profile: products whose components sit comfortably in the SM window, stable programs, and budgets where a verified-hour SM481Plus delivers volume capability at a fraction of new-platform cost. The series' enormous installed base sustains parts supply, service expertise and resale liquidity — the practical risks of used acquisition are lower here than for almost any competing platform. The caveat is horizon: for products that will cross the micro-chip line or demand next-generation speed within the machine's service life, the used route buys a capability ceiling you will outgrow.
The DECAN S2 is the designated successor: it takes the dual-gantry, ten-spindle-per-gantry architecture to roughly 92,000 CPH, adds the 03015 micro-chip floor and a tighter accuracy class, and brings modular track hardware the SM471Plus never offered. For SM471Plus users whose boards never approach 03015, the DECAN F2 delivers most of the same speed at value positioning and is worth demonstrating alongside the flagship. Map the upgrade by product stream rather than fleet-wide, starting with the line whose takt or package roadmap stresses the SM machine first.
Start from the rated figure for each candidate, apply a realistic efficiency factor for your board type — roughly 0.5 to 0.7 of rated for chip-dense products, 0.3 to 0.5 for mixed boards — and divide your placements per board into the resulting rate to get cycle time per board. Then subtract changeover time at your real switching frequency and compare the boards-per-shift result against the schedule, holding 20 to 30 percent margin for growth and process variation. Run that arithmetic for one SM and one DECAN candidate on the same BOM, and the platforms compare themselves in the only currency production actually pays in.
