About antminer hashboard repair
Components of this brochure: The primary story S9 Troubleshooting of different faults in the Operation board, just how to make use of the examination box for precise placing. Variety: Put On All S9 Production, After-sale, Outside the coordination repair work site. 1. Thermostatic soldering Irons(350-400C ), pointer for solder chip resistor capacitors and also various other tiny spots. 2.
We have a large number of Bitmain's Antminer S17 hashboards that we need to perform repairs on, followed by upgrades. Either at the request of customers or because the hashboards are too delaminated. Follow KryptykHex LIVE tonight as he performs these repairs and upgrades on S17 hashboards. Take the opportunity to ask questions in the chat about repairing ASIC hashboards. Take a closer look at what life is like as a bitcoin miner and more specifically as a service provider in the bitcoin mining industry.
Thermal conductive sticky black(3461), Re-glue the heatsink after servicing. 7. Devices for repairing the S11 miner are vital. However when your miner fails, it may additionally be needed to replace some damaged components, such as the air conditioning fan of the miner, the chip warm sink on the hash board, and also the Antminer power line.
Maintenance personnel should have some understanding of electronics, more than one year of maintenance experience, and also master QFN product packaging welding modern technology. 2. After upkeep, the hash board need to be read more tested two times and verified as OK before it can pass! 3. Take notice of the operation method when changing the chip.
4. Identify the upkeep station things and the equivalent test software program specifications and also test fixture. 5. Examine whether the tools as well as components can function typically. 1. 1 S9 is made up of 21 voltage domain names connected in series. There are 3 BM1387 chips in each voltage domain name, and also there are 63 BM1387 chips in the entire board.
5 There are independent small warmth sinks on the front and back of each chip. The small heat sink on the front side is the SMT patch. The small heat sink on the back side is repaired on the back of the IC by the thermal adhesive after the initial measurement.
Note: In the maintenance procedure, in order to lower the damages of the high temperature level of the air weapon to the PCB and the chip when replacing the parts of the electrical board or the chip, it is needed to starting point the tiny warm sink near the defective part as well as the PCB board.
The PCB board has test factors anyway, during the maintenance of the production, the front examination points can be made use of when the warm sink is not connected to the front of the PCB; the finished product repair (after-sales upkeep), because of the front and also back of the PCB covered with heat sinks, it is needed to locate the fault via the test points of the PCB.
