A PCB handling machine that arrives perfect in the crate can still fail on the floor if it is installed against the line it joins or if the people around it never learn to run it, because commissioning and training are where a good purchase becomes a working cell or a delayed one. This guide is a practical checklist you can take from the site survey to the handover, so the loader and unloader are placed, aligned, integrated, tested, and taught in the right order instead of discovered missing after the line is supposed to be running.
The install day is decided weeks earlier by the state of the bay, because a floor that is not ready, a height that is not measured, and a route that is not planned turn a one-day install into a week of delay, and the preparation is the cheapest insurance in the whole project. The line placement plan sets where the machine goes, and this section sets what has to be true at that spot before the crate opens.
Measure the available floor length and the service clearance behind the machine, and confirm the pass-line height at the exact connection point, because a unit that needs a custom stand or that cannot be opened for service once placed is a unit that costs schedule the day it arrives. You record the height and the footprint against the line drawing, not against the brochure, and you confirm the floor is level where the machine will sit so the leveling feet have room to work. The standard versus mini comparison helps you pick a footprint that fits the gap, but the measurement is what confirms the fit, and writing it down is what keeps the install from discovering a mismatch on the day.
Confirm the power type and capacity at the connection point, any compressed air the machine needs, and the earthing, because a handling unit that arrives without the right supply cannot be commissioned no matter how good its build is. You run the utilities to the spot before the install date and you verify them, since a missing air line or an under-rated circuit is the classic cause of a stalled commissioning, and the cost of that stall is the line that waits. The utility check is part of the pre-install list, not a find-on-the-day item, and ticking it early is what lets the install team start work the moment the crate opens. You also confirm there is a labelled disconnect and a suitable breaker at the spot, because a handling unit that must be hard-wired into a distant panel is a unit that is slow to isolate during a fault, and the install is where that safety detail is settled, not the audit.
Plan the route for the signal cable and the E-stop daisy chain before the machine is placed, because a cable draped across a walkway or a safety chain that does not include the new unit is a finding that fails the safety audit and stops the line. You confirm the E-stop passes through the loader and unloader so a stop anywhere halts the whole cell, and you route the signal cable in a tray that will not be walked on or pinched when the machine moves for service. This is the item most often deferred and most likely to bite during commissioning, so writing it into the plan turns a likely finding into a non-event, and it also protects the integration wiring from the damage that would otherwise surface as random stops.
Once the bay is ready, the mechanical alignment to the line is what makes the machine actually hand off boards instead of fighting them, and it is the first thing you verify with a measuring tool rather than an eyeball. The magazine versus vacuum guide covers the mechanism choice, and here the job is to align whatever mechanism you chose to the neighbours it meets.
Set the machine to the measured pass-line height of the neighbouring equipment and align it to the same fixed edge, because a height error or a reversed fixed edge is the one compatibility fault no setting inside the PLC can fix after delivery. You confirm both numbers against the neighbour and you record them, since a height that is twenty millimetres off forces a board to tip or a frame to need shims that should never have been necessary. The magazine loader and every other variant must be set to these values at install, because the alignment is the foundation the rest of the handoff is built on, and getting it right on day one is what prevents the intermittent jams that look like random faults later. You also confirm the machine is leveled and anchored once placed, and that any casters are locked or removed, because a loader that drifts on unlocked casters breaks the height and fixed-edge alignment you so carefully set, and the anchor is also a safety item that ties into the E-stop chain.
Set the width range to cover your board mix and confirm the auto-change returns to the same width every time, because a width that drifts by a few millimetres will eventually misregister a board at the neighbour even if the signals are perfect. You verify the range against your minimum and maximum board widths and you ask how the width is sensed and locked, since a lead-screw with a hard stop behaves very differently over ten thousand cycles than a friction clamp. The buying checklist records the width requirement you specified, and the install is where you confirm the delivered unit actually meets it, because the number on the order is only real once it is measured on the floor.
Draw the line as actually built and set the travel direction and the fixed-edge side at the exact connection point, because a machine shipped with the wrong direction assumption delivers boards against the flow and may not be placeable where intended. You confirm the orientation against the neighbour and you record it, since a board that enters from the correct edge but the wrong end is still a board the downstream tool has to reject or misplace. For lines that wrap a corner, the 90-degree loader unloader for an L-shaped line must be oriented to the turn as built, and the direction check is what keeps the handoff clean all the way around the room rather than only at the first station. You also confirm the orientation is recorded on the line drawing and signed off, because a direction that is correct on the machine but absent from the documentation is a direction that gets re-litigated at the next service, and the record is what keeps the handoff unambiguous for everyone who touches the line later.
With the machine aligned, the electrical handshake and the safety chain are what actually move boards and stop them safely, and these are the items most often assumed rather than verified at install. The SMEMA compatibility checklist is the reference for the signals, and this section turns it into install-day actions.
Power up the unit and confirm it joins the E-stop daisy chain so a stop at any point halts the whole cell, because a loader that keeps feeding a stalled neighbour is both a safety and a yield problem at the same time. You verify the safety signal is exchanged over SMEMA or a hardwire interlock and that the handling machine honours it before it moves a board, and you confirm the behaviour on loss of the signal, since a machine that freezes open is safer than one that keeps moving. This is the install item that most often fails the safety audit, so verifying it on day one turns a likely finding into a non-event and protects both your people and your acceptance date.
Verify the board-ready and board-request signals, the stop and alarm propagation, and the voltage and polarity against the neighbour, because a mismatch here produces the random line stops that look like ghosts and resist diagnosis. You write the signal table down and you test each one during commissioning, since two vendors can label the same function with different names and still be compatible only if the physical connection and polarity are mapped correctly. The NG/OK unloader after inspection depends on this handshake to sort correctly, and the dual-rail variant you may have chosen depends on it to keep two lanes coordinated, so the verification is what makes the integration real rather than assumed.
Map the loader and unloader alarms onto the line stop in a way the neighbour understands, so a magazine-empty alarm halts the line rather than only blinking locally, and confirm the mode state is exchanged so an auto or manual change is honoured at the handoff. You record which alarms are mapped to the SMEMA stop and which are local only, and you confirm the acknowledgment behaviour, because an alarm that stops the line but cannot be cleared from the neighbour forces an operator to walk the cell for every minor fault. The FAT and SAT checklist carries these same points into acceptance, and the install is where you prove them with a test rather than a promise.
The behaviour of the machine is decided in its controller, and configuring the PLC, the recipe handling, and the data path at install is what makes the unit a participant in the line rather than an island. The buying guide specified these capabilities, and here they are switched on and proven.
Configure the controller and the human-machine interface to the line's conventions, and confirm the alarm vocabulary and the mode logic are set so the operators see what they need and the line understands the machine. You prefer a readable HMI with clear alarms and a documented mode logic, because a handling unit with an obscure control is a unit only the original vendor can service, and that dependency costs you during every fault. You also confirm the control system matches what was specified at purchase, since the configuration on the floor is the final proof that the equipment you bought is the equipment you received, and the install is where that proof is recorded. You also confirm the controller firmware matches what was specified and that any line-specific parameters are set, because a handling unit delivered with a generic configuration is a unit that still needs the line's logic loaded before it can join, and the install is where that loading is proven rather than assumed.
Set up the recipe handling so the loader or unloader receives or acts on the line recipe that includes board width, and confirm it signals ready only after it has reached the commanded width, so the line never releases a board into a mismatched rail. You test the auto-change across your product range, because a unit that understands recipe-driven change is compatible with the line you are building, while a manual-only unit is compatible only with the line you used to have. The general guide on choosing loaders and unloaders frames this as a selection criterion, and the install is where the criterion is demonstrated on the floor rather than claimed on the sheet.
Connect the equipment to the line controller or MES so it reports lot identity and state, and confirm the data format is accepted, because a loader that moves boards but cannot report them breaks the traceability the line depends on. For semiconductor-adjacent or regulated flows, the substrate selection guide treats this as a qualification requirement, and the install is where the data path is proven rather than promised. The published interface and handling expectations are maintained by the industry bodies, and the IPC resources on interconnection and handling standards are the place to confirm the conventions rather than relying on a vendor summary, because the standard from the source is what keeps the integration consistent with the rest of your line.
Acceptance is the moment you turn the vendor's claims into your verified facts, and doing it on site, against the line, is what separates a machine that passes on paper from one that runs in production. The FAT and SAT checklist is the full document, and this section applies it to the install-day test.
Understand that factory acceptance happens before shipment and site acceptance after install, and that both should use the same checklist, because a unit that passes one and fails the other is a unit that was never truly verified. You confirm the FAT records travelled with the machine and you re-run the key points at SAT, since shipping and installation can shift an alignment or a setting that was correct at the factory. The two-stage test is what keeps the line from passing acceptance on paper while failing it in production, and treating them as one continuous document is the habit that separates a cell that works from a cell that almost works. You also keep the FAT and SAT records with the machine and the line, because a qualification package that is filed and findable is the one that supports the next audit or requalification, and the discipline of storing it is what keeps the acceptance real years after the install team has left.
Run boards of each product through the loader and unloader and measure the registration at the neighbour, because a handoff that looks smooth can still drift a board out of tolerance once it meets the downstream tool. You test the transfer at the line takt and across the width range, and you confirm the loader delivers each substrate to the same reference every time, since the registration test is the one that catches the alignment error the eyeball missed. For cells that separate good and rejected boards, the NG/OK unloader after inspection has to pass the same registration test in both lanes, because a sorted board that is misregistered is a board that may be routed wrongly.
Trigger each alarm and the SMEMA stop and confirm the whole cell responds correctly, because an alarm that stops the line but cannot be cleared, or a stop that does not propagate, is a safety and a yield fault that only the test will expose. You run the stop and the divert logic with the neighbour present, since the handshake behaviour at the boundary is exactly what fails when two vendors interpreted the standard differently. The test also confirms the mode interlock, because a mode signal that is one short will let the loader feed a machine a human is inside, and the install-day test is the last cheap place to catch that before production.
A machine no one is trained to run is a machine that gets misused until it fails, so training is not a nicety at the end of the project, it is part of the handover that makes the purchase real. The buying guide listed training as a line item, and here is what that line item must actually contain.
Train operators to load and unload correctly, to read the HMI, to recognise a handoff fault, and to perform the basic changeover, because an operator who understands the handoff is the first line of defence against a jam that becomes scrap. You require hands-on sessions, not only a slide deck, and you confirm the operators can run the actual products, since a trained operator is the one who keeps the line moving when the support call is an hour away. The training also covers the safety behaviour, because an operator who knows how the E-stop chain works is the person who stops a fault before it becomes a pile of boards.
Train the maintenance team on the wear items, the transport mechanism, and the spare-parts kit sized to your profile, because a machine that can be serviced on site without stripping it avoids the downtime that a hidden mechanism causes. You confirm the team can perform the width calibration and the belt or chain tensioning, and you review the local spares with them, since the part that stops the line is always the part that is out of stock. The cost and ROI view puts a number on that downtime, and the maintenance training is what keeps the ownership cost predictable instead of surprising, because a team that can act without a vendor on the phone is a team that protects the return you calculated.
Hand over the manual, the wiring diagrams, the spare-parts list, and the acceptance records in a language your team reads, and confirm the documentation covers the control logic and the alarm map, because a manual that only the vendor understands is a manual that is useless during a fault. You verify the IQ/OQ or FAT/SAT records are complete and filed, since those documents are what you rely on for any future requalification or audit. The FAT and SAT checklist is the spine of that package, and a clean handover is what lets the next person service the machine years later without reverse-engineering it from the hardware.
The sections above are the thinking, and this section is the one-page document you actually walk the install and handover against, so nothing is discovered missing after the line is supposed to be running. The same discipline appears in the buying checklist, and here it is ordered to the project timeline.
Before the crate opens, confirm the floor length and service clearance, the measured pass-line height and fixed edge, the power and air at the spot, the E-stop and signal route, and the trained install team, because a bay that is not ready is the most common cause of an install that slips a week. You also confirm the utilities are verified, not merely planned, and you have the neighbour interface photographed and the connector noted, so the install day has no surprises about what is behind the panel. The pre-install list is the cheapest insurance in the project, and ticking it is what lets the install start the moment the equipment arrives.
On the day, confirm the pass-line height and fixed-edge alignment, the width range and repeatability, the travel direction and orientation, the E-stop participation, the SMEMA handshake, and the alarm and mode mapping, because these are the items that make the machine actually join the line. You also photograph the as-built installation, including the connector and the cable route, because a picture of what was actually installed is worth more than a drawing of what was planned when a fault sends someone behind the panel, and the photo is what turns a future mystery into a quick fix. You run each verification with a tool and you record the result, since an install that measures is an install that passes, and the record is what you carry into acceptance. The installation-day list is also where you confirm the recipe and auto-change work across your products, because the configuration on the floor is the final proof the equipment matches the order.
At handover, confirm the operators can run the products, the maintenance team can service the wear items and use the spare kit, and the documentation and acceptance records are complete and filed, because a handover that misses any of these is a handover that fails the first time the line needs it. You sign off the training as a tickable item rather than a verbal yes, and you keep the records with the machine, since a cell that is taught and documented is a cell that keeps running after the vendor leaves. The training and handover list is the last step that turns a delivered machine into a working part of your line, and it is the step most worth refusing to skip.
Most install delays and commissioning failures come from a short list of repeatable mistakes, and naming them up front is what keeps your project from repeating them, because the error that is written down is the error that gets checked. The magazine versus vacuum guide helps you pick the mechanism, and this section keeps the install from undoing that choice.
The most common mistake is aligning the machine by eye or by the brochure height and discovering the mismatch only when boards jam, because a height or fixed-edge error is the one fault no PLC setting fixes after delivery. You measure the pass-line height and the fixed edge at the connection point and you record them, and you treat the measurement as a test with a pass or fail rather than a formality. The line placement plan tells you where the machine goes, but only the on-site measurement confirms it joins the line correctly, and that measurement is what prevents the intermittent stops that look like random faults.
The second mistake is treating the E-stop and the SMEMA handshake as assumed rather than tested, because a safety chain that omits the new unit or a signal that is polarity-inverted passes commissioning on hope and fails it during the safety audit. You run the stop and the handshake with the neighbour present and you record the result, since an alarm that does not propagate or a mode signal that is one short is exactly the fault that injures someone or stops a line later. The SMEMA compatibility checklist is the test plan, and skipping it is the shortcut that costs the most, because the safety finding is the one that stops the whole cell.
The third mistake is cutting training and documentation to lower the price, because a machine no one is trained to run and no one can service from the manual is a machine that fails the first time the line needs it. You keep training and the documentation handover as tickable line items rather than vague promises, since the operator who understands the handoff and the technician who can reach the wear items are what keep the line running after the vendor leaves. The buying checklist lists these as requirements for a reason, and skipping them is the false economy that turns a low quote into a high lifetime cost.
The first thing to prepare is the bay: the floor length and service clearance, the measured pass-line height and fixed edge, the power and air at the spot, and the E-stop and signal route, because a floor that is not ready turns a one-day install into a week of delay. Measure the height and footprint against the line as built rather than the brochure, and photograph the neighbour interface so the install day has no surprises about what is behind the panel.
You verify the board-ready and board-request signals, the stop and alarm propagation, and the voltage and polarity against the neighbouring tool, writing the signal table down and testing each one, because a mismatch produces the random line stops that resist diagnosis. The handshake must be confirmed with a tool and recorded, since two vendors can label the same function differently and still be compatible only if the physical connection and polarity are mapped correctly at the boundary.
Operator training must cover correct loading and unloading, reading the HMI, recognising a handoff fault, performing the basic changeover, and the safety behaviour, because an operator who understands the handoff is the first defence against a jam becoming scrap. Require hands-on sessions on the actual products rather than only a slide deck, since a trained operator keeps the line moving when the support call is an hour away.
Both, using the same checklist: factory acceptance before shipment and site acceptance after install, because a unit that passes one and fails the other was never truly verified, and shipping or installation can shift an alignment. Re-run the key FAT points at SAT so the line does not pass acceptance on paper while failing it in production, and treat the two stages as one continuous document.
The spare-parts kit sized to your profile is what lets the maintenance team act without a vendor on the phone, and training them on the wear items and the kit is what keeps the ownership cost predictable instead of surprising. The part that stops the line is always the part that is out of stock, so a local kit reviewed with the team during training is among the cheapest insurance in the whole ownership model.
The published interface and handling expectations are maintained by the industry standards bodies, and the IPC resources on interconnection and handling standards are the place to confirm the SMEMA interface and related conventions rather than relying on a vendor summary. Confirming the standard from the source keeps your integration consistent with the rest of your line and is the final check before you commit the install.
