BM1360BB tin tool template for repairing your hash board and preparing the ASIC chip before installation. It is made of non-toxic and high-temperature-resistant materials, so it is wear-resistant and tear-resistant, preventing short-circuit failure. In addition, this chip tin mesh saves you time and gives you a smooth finish by applying an even tin coating on your chips for easy soldering with your S19i hash board. The tin planting stencil works better with the Antminer BM1360BB chip tin tool.
