Antminer BM1368 series ASIC chip tester usage tutorial

The BM1368 series ASIC chip test fixture is used for rapidly detecting the quality of ASIC chips. It can reduce the time for us to troubleshoot faulty chips and greatly improve the maintenance efficiency of miners. This article will introduce the specific usage methods of this chip test fixture, which will help us quickly maintain the ASIC chips on the Antminer miner hash board and restore the hash rate. It is suitable for detecting the quality of ASIC chips of Antminer S21XP, S21, T21, and S21Hydro hash boards. Applicable models include BM1368PB, BM1368AA, BM1368PA, and BM1368PV ASIC chips.

I. When we encounter the following situations, the BM1368 chip tester can be used for fault detection:

1. When repairing the hash board, the faulty chip still has faults after multiple repairs.

2. Test the quality of new or second-hand BM1368 series ASIC chips.

II. Understanding the BM1368 series ASIC chip tester

1. Host and 5V adapter

2. Appearance structure of the tester

• Display screen: It mainly displays the test results, including the model and quality of the ASIC chip.

• Test button: After placing the chip to be tested, press to start the test.

• 5V powering interface: It is used for connecting the power adapter to supply to the tester.

• Test socket: After opening the test socket, chips can be placed inside for testing. During the test, the fan above can dissipate heat for the chip.

III. Detailed process of using the BM1368 series ASIC chip tester

1. This time, we use a second-hand BM1368PB chip for testing. First, it needs to be cleaned with circuit board cleaner and dust-free cloth. If it is a new chip, this step is not required.

2. Power on the tester and wait for the screen to light up. Because the chip has not been placed yet, the second row will display "ERROR" in the initial state.

3. Press the fixing buckle upwards to open the test socket. After opening it, we can see the chip test area.

4. At this time, the chip can be placed in the detection area. The positive and negative poles cannot be installed wrongly, otherwise the test result will be incorrect. The " + " on the left corresponds to the positive pole of the chip, and the " - " on the right corresponds to the negative pole.

5. After covering the test socket cover, press the test button. We can see that the upper row displays the chip model, and the lower row displays the test result "PASS", indicating that this is a good chip and can be used continuously.

6. Test another second-hand BM1368PB chip according to the above steps. We can see that its test result shows "ERROR", indicating that this is a faulty chip. If the chip is damaged, it cannot be used continuously. We can choose a new BM1368PB chip for replacement.

The BM1368 series ASIC chip tester, with its efficient and accurate detection capabilities, has solved the problem of chip quality detection for miners. Whether it is troubleshooting during the maintenance process or quality control of new and second-hand chips, it performs well. It can help us quickly detect faulty chips and save maintenance time and costs.
