Detailed Notes on antminer hashboard repair

Materials of this sales brochure: The major tale S9 Troubleshooting of different mistakes in the Operation board, exactly how to use the test box for exact placing. Thermostatic soldering Irons(350-400C ), tip for solder chip resistor capacitors and also various other tiny spots. Devices for repairing the S11 miner are indispensable.

Maintenance workers have to have some knowledge of electronics, more than one year of upkeep experience, and also master QFN product packaging welding technology. 2. After upkeep, the hash board have to be tested two times as well as confirmed as alright before it can pass! 3. Focus on the procedure approach when replacing the chip.

4. Identify the maintenance terminal things and the equivalent examination software specifications as well as test fixture. 5. Examine whether the devices as well as fixtures can work normally. 1. 1 S9 is made up of 21 voltage domain names linked in series. There are 3 BM1387 chips in each voltage domain name, as well as there are 63 BM1387 chips in the entire board.

5 There are independent small warm sinks on the front and back of each chip. The tiny heat sink on the front side is the SMT patch. The little warmth sink on the back side is chosen the back of the IC by the thermal adhesive after the first dimension.

Note: In the maintenance process, in order to decrease the damage of the heat of the air gun to the PCB and the chip when changing the parts of the electric board or the chip, it is required to very first place the tiny warm sink near the malfunctioning element and the PCB board.

The PCB board has examination factors anyway, during the upkeep of the production, the front test factors can be used when the warm sink is not affixed to the front of the PCB; the completed item repair work (after-sales upkeep), due to the front as well as rear of the PCB covered with heat sinks, it is needed to situate the mistake read more via the examination factors of the PCB.
