2. PIC chip voltage test

There is a black dot on the PIC chip, that is the 1st Pin.
Test method: Fluke 17B+ multimeter DC gear, measure whether the 9th Pin of the PIC chip has a voltage output; under normal circumstances, the voltage is about 3.3V. If there is no 3.3V, please check the connection status of the hash board test line to see if the hash board is normal. If it is not normal, you need to re-program the PIC.

3. MOS tube voltage test

There is a white dot next to the MOS tube, which is the 1st Pin. Therefore, the voltage of the MOS tube is the 1st Pin input and the 8th Pin output.
Test method: Fluke 17B+ multimeter is in DC gear, the black test lead is placed on the negative electrode of the capacitor, and the red test lead is placed on the first or eighth Pin of the MOS tube; the input and output values of the MOS tube voltage can be measured, normal There will be 18V input and output.
If the voltage is abnormal, it is necessary to measure the ground value of the MOS tube.
Grounding value detection method: Fluke 17B+ multimeter diode gear, the red test lead is placed on the negative electrode of the capacitor, and the black test lead is placed 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. LDO 1.8V and PLL 0.8V output voltage test

There is a white dot next to LDO 1.8V, which is the 1st Pin. The LDO 1.8V voltage is the 1st Pin input and the 5th Pin output.
Test method: The multimeter is in DC gear, the black test lead is placed on the heat sink of the same domain, the red test lead is placed on the 1st pin, there will normally be 3.2V input, and the red test lead is placed on the 5th pin, normally there will be 1.8V output.
There is a white dot next to PLL 0.8V, which is the 1st Pin. PLL 0.8V voltage is the 1st Pin input and the 5th Pin output.
Test method: The multimeter is in DC gear, the black test lead is placed on the heat sink of the same domain, 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, normally there will be 0.8V output.
If the voltage is abnormal, it is necessary to measure the ground value of LDO 1.8V and PLL 0.8V.
Ground value detection method: Fluke 17B+ multimeter diode gear, red test lead is placed on the heat sink of the same domain, black test lead is placed 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)

5. 24V voltage test

Through the two ends of the black capacitor, the 24V voltage can be measured.
Test method: Fluke 17B+ multimeter is in DC gear, the red test lead is placed on the positive pole of the capacitor power interface, and the black lead is placed on the negative pole of the capacitor.

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.
