Antminer BM1764 1*4 chip tin tool can quickly replace the ASIC chip of the Antminer D7 hash board. The tool is made of high-quality steel mesh with accurate and smooth holes, which can effectively prevent the generation of static electricity and damage the chip pins. The tin fixture can tin 4 BM1764 and BM1764AB chips at the same time. High-temperature and wear resistance are very convenient to use, saving tinning time and cost. This product is suitable for direct heating, which is more convenient and quick to complete the tinning work.
