Problems solved by technology

[0002] With the development of electronic products, due to the constraints of various functions and conditions of use, the components on the PCB show a trend of diversification. There are all through-hole plug-in PCBs, all patch PCBs, and plug-in mixed PCBs. The current The process is that all through-hole plug-in PCBs are soldered with a wave soldering machine; all patch PCBs are soldered with a reflow soldering machine; there are two types of plug-in mixed PCBs, and the plug-in mixed components on the same side of the PCB are first soldered with a reflow soldering machine Mount the components, and then solder the plug-in components with a wave soldering machine; if the plug-in mixed components are not on the same side of the PCB, first use the reflow soldering machine to solder the mounted components, and then manually solder the plug-in components, because if you use a wave soldering machine to solder the plug-in components Mounted components will affect soldered mounted components

Abstract

The invention discloses a reciprocating type printed circuit board (PCB) selective crest welder. The reciprocating type PCB selective crest welder is mainly comprises a selective scaling powder coating device, a pre-heating device, a welding device and a PCB transmission and positioning device. According to the reciprocating type PCB selective crest welder, a PCB to be welded is pre-heated after being coated with the selective scaling powder, selective welding is carried out on the PCB, and then the PCB is returned along the same track after the welding is finished, and therefore a reciprocating type welding process is achieved. The reciprocating type PCB selective crest welder is simple in structure, convenient to operate, high in precision, and universally applicable to selective welding of various PCBs.
