Selective Soldering Machine 101


Selective-Soldering Machine Overview


Engineered and built in China, the I.C.T selective-soldering machine is the go-to SMT selective wave soldering machine for high-mix, high-volume lines. The PCB stays perfectly still while the lightweight cast-aluminum platform—powered by Panasonic servos and precision linear rails—moves flux and solder heads with whisper-quiet speed and pinpoint accuracy. Inline nitrogen heating delivers perfect wetting and almost no dross. Every parameter is dialed in and saved in an easy Windows interface for rock-solid repeatability. Automatic wave calibration, real-time CCD monitoring, German jet valve, and titanium pot keep quality sky-high and rework at zero shift after shift.


DIP Line Equipment List


Precision Flux Application

1-1 Precision Flux Application


A German high-frequency jet valve shoots tiny, perfect flux dots with solids under 10%. Pressure tank plus precision flow meter keep flow dead-steady no matter the tank level. The nozzle sits on an XY platform repeatable to 0.02 mm. Dropped residue lands in a slide-out tray for instant cleanup. All pneumatics are bulletproof Japanese SMC, gauges right on the surface for quick checks. An automatic pump feeds flux without a hiccup. This system nails clean, repeatable coverage every cycle on the selective-soldering machine.


Efficient Preheat Optimization

2-1 Efficient Preheat Optimization


Fully adjustable bottom IR is standard; top IR or hot-air convection optional. Open design spreads heat evenly while thick insulation holds rock-steady temps. Premium elements and motors from global leaders run trouble-free for years. Everything is plug-and-play—no tools needed for service. Boards come out perfectly activated and stress-free, ready for flawless solder joints in the SMT selective wave soldering machine.


Bulletproof Soldering Core

3-1 Advanced Soldering Technology


German electromagnetic pump creates an ultra-stable wave peak. Set temperature, N2 flow, height, and auto-calibration straight from the screen. Titanium pot with external cast-iron heater warms fast and never leaks. Inline nitrogen gives shiny joints and virtually zero dross. Real-time CCD records 900 hours of traceable video. Sealed high-speed XYZ axes, laser wave detection, and automatic nozzle cleaning keep the selective-soldering machine humming 24/7.


Durable Transmission Design

4-1 Durable Transmission Design


Heavy-duty profiled rails and three-section roller conveyor move boards smoothly. Side and top clamps lock the PCBA dead-still during every step. Thickened rails handle 20 kg loads with ease. Precision drive modules position boards perfectly from flux to solder. The whole transport system is built for nonstop production on the SMT selective wave soldering machine.


Reliable Control Integration

5-1 Reliable Control Integration


CE-certified PLC and high-speed bus architecture meet Industry 4.0 standards. Cat-6 wiring and top-tier electronics deliver lightning-fast response and total reliability. Guided programming, auto nozzle recognition, picture-based edits, one-click live view, and multi-language support make setup a snap. Full traceability keeps quality locked in on every selective-soldering machine.

User-Friendly Operating Interface

6-1 User-Friendly Operating Interface


Step-by-step guided mode, automatic nozzle ID, smart picture correction, real-time dashboards, and one-button live CCD make running the machine a breeze. Supports Chinese, English, Japanese, Russian and more. Built-in MES, Wi-Fi, remote access, voice alerts, and customizable lights keep operators in full control of the SMT selective wave soldering machine.
