As we all know, the Avalon A8 series is an aluminum-based hash board. The maintenance method of this hash board is slightly different from other ones, but the most important thing is the welding method of ASIC chips and components on the hash board. The A8 series repair tutorial launched by ZMRC will explain the working principle of the hash board and the specific maintenance method after failure. For example, when the single board test reports 0, what is the maintenance idea? If the signal is abnormal, how should we use the oscilloscope to measure the signal? What is the method of operation when it is time to replace an ASIC chip or component? Here, youll find course video instructions for these breakdowns.
