Click to view: Fix Description of Antminer Hashboard test points. The whole board has 78 chips, divided into 13 voltage domains, and each voltage domain contains 6 chips. For the description of the voltage domain, please refer to the following articles:. Explanation of the voltage domain of Antminer Hash Board.

At the same time, we also provide a more detailed circuit diagram for reference:. Antminer T17e hash board repair guide download address:. Video tutorial for Hashboard inspection and repair, example model: S9. The detection and repair methods of most miners in Antminer are basically the same. Click to watch: AntminerS9 hash board repair and fault diagnosis video tutorial.

Related maintenance tools:. New version of multifunctional test fixture. Chip Tin Tool. Refer to the range of voltage values described by the signal direction. If the measurement encounters a large deviation in voltage value, it can be compared with the measured values of adjacent groups.

Assuming that the chip signal pin output voltage is normal, if the chip is still incomplete, for example, if 77 chips are detected, you can troubleshoot by shorting RO and 1. If 77 chips can be detected after shorting, it indicate that chips should be normal, and you can troubleshoot the 78th chip at this time. If 76 chips are detected after short-circuiting, conduct troubleshooting forward; it is recommended to adopt the dichotomy method for troubleshooting, that is, test from the middle the 39 th one is checked, and each domain can be operated in this way.

Phenomenon: single board pattern NG, that is, the response nonce data is incomplete PT2 station type. The serial port is connected to the computer, and the computer reads the test log; according to the results displayed in the log, the chip position of insufficient nonce data can be determined; replace the chip at the corresponding position.

Check the quality of the front and back chip heat sinks connected to the temperature sensor. If the heat sink is not welded well, it will affect the temperature difference. First step: check whether the voltages at several voltage output points are normal. You can disconnect U8 first if 3. If the short circuit still exists, you can unplug the CPU for measurement. For other voltage abnormalities, replace the corresponding transformer IC in general. Probably the IP is not found due to abnormal operation.

Refer to point 1 for troubleshooting. Check the appearance and soldering of the network port, network transformer T1, and CPU. With reference to the test process documents, the general problems are assembly process issues and control board process issues. Common phenomena: IP is not detected, the number of fans is abnormal, and the chain is abnormal.

Low aging hashrate: Check the hashrate deviation of the corresponding hash board, check if there is a large hash rate difference. Take out the hash board with a large hashrate difference for testing and maintenance. Check if the network has a low average hashrate caused by interruption. Large aging temperature difference: check the aging environment; for high-temperature boards, check the soldering quality of the heat sinks of the hash board.

Aging miner protection: Generally it is over temperature protection. Please control the aging environment temperature to be less than 40 degrees Celsius. If one of the chains cannot be detected, the miner shall be disassembled and tested on the corresponding hash board; if the hash board is determined to be faulty, the hash board shall be repaired, and if the control board is tested to be faulty, the control board shall be repaired. Refer to the above steps for troubleshooting.

For related test procedures and use of test fixtures, please communicate with the after-sales engineer for details of the use. After repair, you can use the non-scanning mode to test PT2. If yes, it must be handled first; check whether there are any parts with obvious burn marks, collision offset or missing parts, etc. If yes, it must be handled first.

Third, check whether the voltage of each domain is about 1. The method is to add a flux around the chip preferably no-clean flux , and heat the solder joints of the chip pins to a dissolved status, so as to promote the chip pins and the pads to re-run, then removing tin finally, thus achieving the effect of re-tinning.

If the failure is the same after re-soldering, the chip shall be replaced directly. For the first time, after the replacement of the accessories is complete, wait for the hash board to cool down and perform fixture test, after passing, set it aside and then cool it down; for the second time, wait for a few minutes until the hash board is completely cooled before testing. Antminer T17e Hash Board Repair Guide Edition Date: File category: Maintenance program Content of this volume: mainly describe how to troubleshoot various faults of the T17e hash board, and how to use test fixtures for accurate positioning.

Platform requirements: Rubber mat maintenance platform the platform needs to be grounded , anti static wrist band and ground connection. Demand for common maintenance spare materials: resistance 0R, 33R, 1K, 4. Figure 7. Production of fixtures and precautions The supporting clamps of the fixture should meet the requirements for heat dissipation of the hash board and facilitate the measurement of signals.

Figure Figure 3. The single-sided heat sink uses the file before brushing to make the SD card; the double-sided heat sink uses the file after brushing to make the SD card for batch testing of production subcontractors Figure 4.

Principle overview 1. T17e hash board working structure: The hash board is composed of 78 BM chips , which are divided into 13 groups, each group is composed of 6 ICs; the working voltage of the BM chip used by the T17e hash board is 1. Figure 2. T17e hash board boost circuit: The boost is from 21V to Figure 3. T17e chip signal direction: 3. Figure 4.

Figure V. Please check the circled part in Figure Figure Step two: check the voltage domain voltage output The voltage in each voltage domain is about 1. Figure Step three: check the PIC circuit Measure whether the second pin of U3 has an output, the voltage is about 3.

Program the PIC program of the arithmetic board. Figure Step five: check the LDO 1. Figure Assuming that the chip signal pin output voltage is normal, if the chip is still incomplete, for example, if 77 chips are detected, you can troubleshoot by shorting RO and 1. Phenomenon: single board pattern NG, that is, the response nonce data is incomplete PT2 station type The serial port is connected to the computer, and the computer reads the test log; according to the results displayed in the log, the chip position of insufficient nonce data can be determined; replace the chip at the corresponding position.
