The PCB board usually contains power circuit, control circuit, protection circuit and other parts, which work together to ensure the normal operation of the charging gun.

[0003] The design and manufacture of PCB boards need to take into account factors such as the power requirements, safety, reliability, and production costs of the charging gun. Therefore, when designing and manufacturing PCB boards, various factors need to be fully considered to ensure that they can meet the requirements of the charging gun. In the process of PCB board production, connecting cables is a key step. Usually, we use solder to solder the cables to the PCB board.

This means that workers may be burned by the high-temperature soldering iron tip during operation. In addition, a pungent odor is emitted during the soldering process, which not only affects the environment but also poses a threat to workers' health. In addition, the current soldering process is prone to copper peeling off during PCB soldering, resulting in a high defective rate. Utility Model Content
