Selective wave soldering generally consists of three modules, namely flux spraying, preheating and soldering. The soldering flux spraying module can finish selective spraying of the soldering flux on each welding point in sequence through the equipment programming device, and after the soldering flux is preheated by the preheating module, the soldering module finishes soldering on each welding point by point.
Selective wave soldering apparatus is considered to be an automated apparatus that replaces manual soldering, and can solder a single spot, but there are many problems in actual production if it is to be replaced completely. For example: when the light-emitting diode is manually welded, the light-emitting diode needs to be tightly attached to a printed board by hands, pins are welded on the back surface of the board, and if the light-emitting diode is directly placed into selective wave soldering equipment, the light-emitting diode can be jacked up when soldering tin is used for welding from the lower direction, so that automatic processing cannot be finished.
If the robot is adopted to simulate manual welding, a large amount of capital is required to be invested, and even a workshop needs to be reconstructed; if adopt tray formula welding frock, can put whole printed board subassembly earlier on tray formula welding frock during the use, the fixed components and parts (emitting diode and printed board) that need stabilize of spring buckle on the reuse frock then carry out selectivity wave-soldering welding, but this frock structure is complicated, and manufacturing cost is higher, and the spring buckle location is not accurate enough moreover, is difficult for adjusting.
