hashboard repair - An Overview

Components of this sales brochure: The major tale S9 Troubleshooting of various faults in the Operation board, how to use the test box for precise positioning. Thermostatic soldering Irons(350-400C ), idea for solder chip resistor capacitors and also various other little patches. Tools for repairing the S11 miner are important.

After maintenance, the hash board should be tested two times and also validated as Okay before it can pass! Pay attention to the procedure technique when replacing the chip.

4. Identify the maintenance terminal item and the corresponding examination software application specifications and examination fixture. 5. Check whether the devices as well as fixtures can function typically. 1. 1 S9 is composed of 21 voltage domains attached in collection. There are 3 BM1387 chips in each voltage domain name, and there are 63 BM1387 contribute the entire board.

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

Keep in mind: In the maintenance process, in order to lower the damage of the high temperature level of the air gun to the PCB as well as the chip when changing the components of the electrical board or the chip, it is necessary to top place the small warm sink near the damaged component and also the PCB board.

The PCB board has examination points anyway, throughout the upkeep of the production, the front test factors can be made use of when the heat sink is not connected to the front of the PCB; the ended up product repair work (after-sales upkeep), as read more a result of the front and back of the PCB covered with warm sinks, it is essential to locate the fault with the test factors of the PCB.
