Description

Technical Field

[0001] The utility model relates to the technical field of electric testers, in particular to an electric tester for detecting PCB boards. Background Art

[0002] In the PCB industry, the test results at two different time points are different due to the physical pressure and high voltage electric shock on the PCB board. After all, both states are tested by the tester, so it cannot be said that the tester missed the test. This can only be said to be a concept of leakage that exceeds the scope of the tester's capabilities. The leakage can only be reduced, but not eliminated. With the rapid development of science and technology, our demand for production efficiency has also increased. During the process of electrical testing, PCB boards need to be tested. The current equipment cannot guarantee high production efficiency, and it also brings a heavy workload to the staff.

In this way, the PCB board cannot be clamped during the detection, so that the detection speed of the PCB board is slow, which cannot meet the needs of rapid detection and reduces work efficiency.
