Antminer S19 hash board repair tutorial

Antminer S19 hash board repair tutorial Antminer S19 hash board has a total of 76 BM1398 ASIC chips and is powered by APW12 PSU. The MOS tubes on the S19 hash board is different from the 17 series. The conduction condition of these 4 MOS tubes is that their G-pole input is high level, and they will not play a role in reducing the voltage in the circuit. When the PIC chip is working normally and 3.3V is input, the four MOS tubes will be turned on. Each domain has only one LDO1.8V and PLL 0.8V, and all 0.8V is powered by the LDO1.8V of this domain. Quickly learn how to properly repair an S19 hash board with the Antminer S19 hash board repair tutorial video.

This training course video is about the Antminer S19 troubleshooting for the hash board's circuit basics and working principles.

The 76 chips on the Bitmain S19 hash board will perform high-speed hash rate operations. When testing a single board, the test log will display the specific faulty ASIC chip number. It is very important to determine the chip arrangement.

The figure below marks the specific distribution of each ASIC chip on the front and back of the Antminer S19 hash board:



Antminer S19 hash board has 2 boost circuits, the 21V boost circuit is used to turn on the 4 MOS tubes; the 19V boost circuit is used to power the LDO1.8V chips in the last 7 domains. If the powering is abnormal, subsequent LDO1.8V and PPL0.8V may not work properly.

The BM1398 ASIC chip on the S19 hashboard has a total of 5 signals, and their transmission directions are:

CLK signal: No.1 → No.76 ASIC chip

CO signal: No.1 → No.76 ASIC chip

RI signal: No.1 ← No.76 ASIC chip

BO signal: No.1 → No.76 ASIC chip

RST signal: No.1 → No.76 ASIC chip

The ZMRC Antminer repair course will help you remember the S19 hash board structure and working principle, so as to master professional repair skills.
