Voltage and ground value test of Antminer S17+ power supply unit

1. 21V voltage test

Test method: adjust the fluke multimeter to DC gear, put the red test lead on the positive pole of the hash board power interface and the black lead on the negative pole of the power interface.
test point

2. PIC chip voltage test

There's a black spot on the PIC chip, that's the 1st Pin.
Test method: multimeter DC gear, measure whether the 2ed Pin of the PIC chip has output; the normal voltage is about 3.3V. If there is no 3.3V, please check the connection status of the hash board test line, whether the hash board is normal, and if not, re-program the PIC.

3. MOS tube voltage test

There is a white dot next to the MOS tube, which is 1st Pin. The voltage of the MOS tube is the 1st Pin input and the 8th Pin output.
Test method: the multimeter is in DC gear, the black test lead is placed on the negative pole of the capacitor, and the red test lead is placed on the first or 8th Pin of the MOS tube. The input and output values of the MOS tube voltage can be measured. Normally, there will be 21V input and output. 
If the voltage is abnormal, it is necessary to measure the ground value of the MOS tube. Adjust the multimeter to the diode gear, put the red test lead on the capacitor's negative pole and put the black test lead on the 1st or 8th Pin of the MOS tube. If the ground value is abnormal, replace the MOS tube. (To judge whether the resistance value of the MOS tube is abnormal, you can compare it with other MOS tubes)

4. 24V voltage test

Through D5 / D8, 24V voltage can be measured.
Test method: the multimeter is in DC gear, and the red and black test leads are placed on both ends of D5 or D8 respectively.
24V voltage test

5. LDO 1.8V and PLL 0.8V output voltage test

There is a white dot next to LDO 1.8V, which is 1st Pin. The LDO 1.8V voltage is the 1st Pin input and the 6th Pin output.
Test method: the multimeter is in DC gear, the black test lead is placed on the heat sink of the same domain, and the red test lead is placed on the 1st Pin, normally there will be 3.5V input, the red test lead is placed on the 6th Pin, and there will be 1.8V output normally.
There is a white dot next to PLL 0.8V, which is 1st Pin. PLL 0.8V voltage is the input of 1st Pin and the output of 5th Pin.
Test method: the multimeter is in DC gear, the black test lead is placed on the heat sink of the same domain, and the red test lead is placed on the 1st Pin, normally there will be 1.8V input, and the red test lead is placed on the 5th Pin, and there will be 0.8V output normally. 
If the voltage is abnormal, it is necessary to measure the ground value of LDO 1.8V and PLL 0.8V. Adjust the multimeter to the diode gear, put the red test lead on the same domain's heat sink and put the black test lead on the 1st Pin. If the ground value is abnormal, replace the corresponding LDO 1.8V and PLL 0.8V. (To judge whether the resistance of LDO 1.8V and PLL 0.8V is abnormal, you can compare other LDO 1.8V and PLL 0.8V)

How to repair ASIC miner hash board

How to repair ASIC miner hash board Important parts of ASIC miners – Hash board One  ASIC miner consists of 3 to 5 Hash board, a control board, a casing, and software, among which the Hash board are easiest  to broken. because the ASIC bitcoin miner hash board consists of many serially connected ASIC chips. When they work, they will be in a high-temperature environment for a long time. In this environment, it is easy to burn the chip or scatter the solder due to high temperature which makes the hash board or the mining machine unable to work and no hash rate. How to quickly detective which chips broken it’s the most important when we repairing ASIC miners The Antminer chips fixture fast efficient and easy to use Bitmain Antminer repair inspection tool The ASIC bitcoin miner hash board consists of many serially connected ASIC chips.
