About antminer hashboard repair

Materials of this brochure: The main story S9 Troubleshooting of different mistakes in the Procedure board, just how to use the test box for precise positioning. Thermostatic soldering Irons(350-400C ), tip for solder chip resistor capacitors as well as other small patches. Tools for fixing the S11 miner are important.

After maintenance, the hash board have to be checked two times and also verified as OK prior to it can pass! Pay attention to the procedure method when changing the chip.

4. Identify the upkeep station things as well as the matching examination software program parameters and examination component. 5. Examine whether the tools and fixtures can work generally. 1. 1 S9 is composed of 21 voltage domains linked in collection. There are 3 BM1387 chips in each voltage domain name, and there are 63 BM1387 chips in the whole board.

5 There are independent tiny warm sinks on the front as well as back of each chip. The little heat sink on the front side is the SMT patch.

Keep in mind: In the upkeep process, in order to reduce the damages of the high temperature level of the air weapon to the PCB and the chip when changing the parts of the electric board or the chip, it is required to first area the little heat sink near the faulty part as well as the PCB board.

The PCB board has examination points anyhow, during the upkeep of the production, the front examination factors can be utilized when the warmth sink is not connected to the front of the PCB; the ended up product fixing (after-sales maintenance), as a result of the front and rear of the PCB covered with warmth sinks, it is needed hashboard repair to situate the fault with the examination factors of the PCB.
