Antminer DR5 ASIC chip BM1725AA tin tool BM1725AA chip tinning tool for ASIC chip replacement and tinning for Antminer DR5 hash board. Tin tools are made of electric and high-temperature resistant composite materials, which are more durable than alloy materials. In the process of replacing the chip, it can effectively prevent the generation of charge and protect the chip. The steel mesh is made of high-quality materials, with precise positioning, high-temperature resistance, and no deformation.
