5 Simple Statements About asic repair Explained

Materials of this pamphlet: The primary tale S9 Troubleshooting of numerous mistakes in the Procedure board, just how to use the examination box for accurate positioning. Thermostatic soldering Irons(350-400C ), idea for solder chip resistor capacitors and also various other tiny spots. Devices for fixing the S11 miner are important.

After maintenance, the hash board have to be examined two times and also verified as OK before it can pass! Pay focus to the procedure method when replacing the chip.

4. Identify the maintenance terminal object as well as the corresponding examination software criteria and test component. 5. Check whether the tools and also components can work generally. 1. 1 S9 is made up of 21 voltage domain names connected in collection. There are 3 BM1387 chips in each voltage domain, as well as there are 63 BM1387 chips in the entire board.

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

Keep in mind: In the upkeep procedure, in order to reduce the damages of the heat of the air weapon to click this link the PCB and also the chip when replacing the parts of the electric board or the chip, it is essential to starting point the little warm sink near the damaged component as well as 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), due to the front as well as rear of the PCB covered with warmth sinks, it is necessary to find the fault with the examination factors of the PCB.
