The principle of the Antminer chip test fixture is to send a test signal (from the first chip to the last chip) to scan the entire hash board. When the test signal reaches the location of the faulty chip, because the chip has been damaged, the test signal will be cut off there, and the number of the corresponding chip will be reported to the PC. https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=388
