Fascination About hashboard repair

Materials of this sales brochure: The main tale S9 Troubleshooting of various faults in the Procedure board, how to utilize the examination box for accurate positioning. Thermostatic soldering Irons(350-400C ), idea for solder chip resistor capacitors as well as various other small spots. Devices for fixing the S11 miner are vital.

Upkeep personnel need to have some expertise of electronic devices, greater than one year of maintenance experience, and also master QFN product packaging welding innovation. 2. After upkeep, the hash board should be checked 2 times and validated as okay before it can pass! 3. Take note of the operation technique when changing the chip.

4. Identify the maintenance station item as well as the matching examination software parameters as well as examination component. 5. Examine whether the devices and 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, and there are 63 BM1387 chips in the entire board.

5 There are independent tiny heat sinks on the front as well as rear of each chip. The small heat sink on the front side is the SMT spot. The little heat sink on the back side is chosen the rear of the IC by the thermal adhesive after the initial dimension.

Keep in mind: In the maintenance procedure, in order to reduce the damages of the heat of the air weapon to the PCB and the chip when changing the elements of the electrical board or the chip, it is required to starting point the little warmth sink near the defective part and also the PCB board.

The antminer hashboard repair PCB board has test points anyway, during the maintenance of the production, the front test factors can be made use of when the warmth sink is not connected to the front of the PCB; the finished product repair work (after-sales maintenance), due to the front and back of the PCB covered with warmth sinks, it is necessary to locate the mistake via the test factors of the PCB.
