MSI-400 | Inline Integrated Selective Wave Soldering Machine
The MSI-400 is an advanced selective soldering machine designed for precision and efficiency in electronic manufacturing
Process Flow
| Stage | Operation | Description |
|---|---|---|
| 1. PCB Loading | In-line Conveyor Inlet | PCBs automatically enter the machine via the upstream conveyor system, seamlessly integrated with SMT production lines |
| 2. Flux Application | Selective Flux Spraying | The XYZ servo motion platform precisely moves the PCB above the flux spray valve, applying flux only to designated solder points according to programmed paths (Visual programming/Gerber compatible) |
| 3. Preheating | Upper Infrared Preheating | The PCB passes through the top infrared preheating zone to activate the flux and gradually raise the board temperature to prevent thermal shock during soldering |
| 4. Selective Soldering | Mini-wave Soldering | Using the same XYZ motion platform, the PCB moves above the selective solder fountain/nozzle,精确焊接 only the targeted through-hole components while avoiding temperature-sensitive SMDs |
| 5. PCB Unloading | In-line Conveyor Outlet | The completed board exits to the downstream conveyor for further processing or inspection |

1.Fully Automated In-line Operation: Continuous flow without manual loading/unloading interruptions
2.Shared XYZ Platform: Same precision servo system handles both fluxing and soldering operations, ensuring positional accuracy (±0.05mm)
3.Selective Processing: Only fluxes and solders designated areas, protecting nearby heat-sensitive components
4.Seamless SMT Integration: Direct connection with reflow ovens, AOI systems, and other inline equipment for high-volume manufacturing
Ideal for: High-volume production of mixed-technology PCBs (SMT + Through-hole) in automotive electronics, industrial controls, and communication equipment.
