What Are the Common Procedures for Repairing Antminer L3+ Hash Board?

Common repair process 1. Routine inspection: First of all, visually inspect the hash board to be repaired to observe whether there is any displacement, deformation, or scorching of the small heat sink? If any, you must deal with it first; if the small heat sink is displaced, remove it first, wash off the original glue, and re-adhesive after the repair is passed. Secondly, after the visual inspection is no problem, the impedance of each voltage domain can be tested first to detect whether there is a short circuit or an open circuit. If found, it must be dealt with first. Thirdly, check whether the voltage of each voltage domain reaches 0.8V, and the voltage difference of each voltage domain shall not exceed 0.05V. If the voltage of a certain voltage domain is too high or too low, the circuits in the adjacent voltage domain generally have abnormal phenomena. Need to investigate the reason first. 2. After the routine test is no problem (the short-circuit test of the general routine test i
