Components of this brochure: The main tale S9 Troubleshooting of different mistakes in the Operation board, how to utilize the test box for exact positioning. Thermostatic soldering Irons(350-400C ), pointer for solder chip resistor capacitors as well as various other little spots. Tools for fixing the S11 miner are important.

Upkeep workers have to have some understanding of electronic devices, greater than one year of maintenance experience, and master QFN packaging welding modern technology. 2. After maintenance, the hash board have to be tested two times and also confirmed as okay prior to it can pass! 3. Take notice of the operation method when replacing the chip.

Inspect whether the devices and also components can work typically. 1. 1 S9 is composed of 21 voltage domain names official web site connected in series.

5 There are independent tiny warm sinks on the front and back of each chip. The tiny warm sink on the front side is the SMT spot.

Note: In the upkeep procedure, in order to decrease the damage of the heat of the air weapon to the PCB and the chip when replacing the parts of the electric board or the chip, it is needed to top place the small heat sink near the damaged element and also the PCB board.

The PCB board has test points anyway, throughout the upkeep of the production, the front test points can be used when the heat sink is not affixed to the front of the PCB; the finished item repair work (after-sales maintenance), due to the front and also rear of the PCB covered with warm sinks, it is necessary to locate the mistake via the examination points of the PCB.
