BM1397 1*4 stencil is a stencil that can tin 4 BM1397 chips simultaneously. Compared with the ordinary BM1397 tin planting stations, the quantity of tin planting is more, and the completion speed is faster. However, due to the long-term use of the steel mesh, there may be inaccurate tinning and rust. Replace the tin-planting stencil in time to ensure the tinning accuracy and the hash board's stable operation. This tinned steel mesh is suitable for tinning replacement of 7nm ASIC chips for miners such as Antminer S17, S17+, S17 Pro, T17, and T17+.
