[0002] The circuit board is mainly composed of two types of materials: insulating substrate and conductor. It plays the role of support, interconnection and partial circuit components in electronic equipment. Integrated circuits and electronic components such as resistors and capacitors cannot function as single individuals. Only when they have a foothold on the printed circuit board and have conductive junctions to connect them can they play their functions in the whole. The circuit board is the skeleton that supports components and the pipeline that connects electrical signals.

[0003] When processing existing circuit boards, most of them are fixed on the processing table, and then the electronic components are soldered on the circuit boards using a welding gun. However, when fixing the circuit boards, most of them are fixed by threaded rod clamping. When the clamping force is too large, it is easy to cause damage to the circuit board.

[0016] 1. The present invention has a reasonable structure.
