The chip tinning tool is a multi-functional test fixture integrating 9 kinds of chips, including T1558, T1668, KF1921, BM1397, T1S16, BM1362, BM1485, T1338, and T4U16. It is convenient and faster to tin-plate multiple different chips simultaneously. Using electric and high-temperature resistant composite materials can effectively prevent the generation of charges and protect the chip during the process of replacing the chip. High-quality steel mesh, precise positioning of holes. It is convenient for the precise tinning of chips. Long service life, high temperature, and wear resistance increase the probability of successful chip welding.
