[0002] SMT is surface assembly technology (surface mount technology), which is the most popular technology and process in the electronic assembly industry; solder paste is also called solder paste, a gray paste. Solder paste is a new type of welding material that came into being with SMT. It is a paste mixture formed by mixing solder powder, flux and other surfactants, thixotropic agents, etc. It is mainly used for the welding of electronic components such as resistors, capacitors, ICs, etc. on the surface of PCB boards in the SMT industry.

This process is relatively cumbersome and reduces the detection efficiency. In view of the above problems, the inventor proposes a short-circuit stripping device for solder paste detection equipment to solve the above problems. Utility Model Content
