选择性焊接的工艺流程包括:助焊剂喷涂,电路板预热、浸焊和拖焊。助焊剂涂布工艺在选择性焊接中,助焊剂涂布工序起着重要的作用。焊接加热与焊接结束时,助焊剂应有足够的活性防止桥接的产生并防止电路板产生氧化。助焊剂喷涂由X/Y机械手携带电路板通过助焊剂喷嘴上方,助焊剂喷涂到pcb电路板焊位置上。
The process flow of selective welding includes: flux spraying, circuit board preheating, immersion welding and drag welding. Flux coating process in selective welding, flux coating process plays an important role. At the end of welding heating and welding, the flux shall have sufficient activity to prevent bridging and oxidation of the circuit board. Flux spraying is carried by X / y manipulator. The circuit board passes above the flux nozzle, and the flux is sprayed on the welding position of PCB circuit board.
