The key defect of the current ID control board mounting seat is its depth design problem, and due to the depth design defect, the ID control board cannot be pressed down to a sufficient depth after being installed on the high-fidelity test interface board, resulting in unstable contact with the spring ejector conductive connector on the test head, frequent alarms during the operation of the machine in the morning, and the current ID control board mounting seat is made of aluminum alloy material. In a high temperature environment, due to the thermal expansion and contraction properties of metal, the ID control board will be stuck in the mounting seat and difficult to remove when disassembling the ID control board. The above situation causes the equipment to be unable to identify the ID of the high-fidelity test interface board during the test process, thereby causing the equipment to alarm and shut down, causing great trouble and downtime losses to the development of the storage chip testing business, especially when personnel need to perform maintenance, each operation is very troublesome and the workload is heavy.
