BM1397 chip tin fixture four in one Bitmain Antminer S17, T17 series miners have a high hash rate, but due to the unstable adhesion of the heat sink, the hot air cannot be circulated well, the temperature is too high, the chip is burned or a short circuit is caused. The solution to this problem is to restore the stability of the hash board by replacing the ASIC BM1397 series chip. The tin fixture can tin 4 chips at one time. Compared with the ordinary BM1397 tin planting station, the number of tin is more and the completion speed is faster. It is a utility tool for repairing and replacing hash board chips. This tin template is suitable for tinning and replacement of 7nm ASIC chip of Antminer S17, S17+, S17 Pro, T17, T17+, and other mining rigs.
