The invention relates to an ICT extension clamp for testing the number of PCBA board needle points and a testing method thereof. The ICT extension clamp comprises a PCBA placing board, a probe assembly, an interface board, an interface needle assembly, a first wire, a second wire, a third wire, a clamp shell and a relay. The PCBA placing board is installed at the top end of the clamp shell in a covering and sealing mode, and the probe assembly is arranged in the PCBA placing board. The interface board is packaged at the bottom end of the clamp shell, and interface needles are all arranged in the interface board; the probe assembly comprises a first probe and a second probe, the tail end of the first probe is connected with one end of the first wire, and the other end of the first wire is connected with the first interface needle; and the tail end of the second probe is connected with one end of the second wire, the other end of the second wire is connected with the relay, one end of the third wire is connected with the relay, and the other end of the third wire is connected with the second interface needle. The ICT extension clamp is convenient to operate, high in working efficiency, simple in structure and high in practicability, and the hardware cost is greatly reduced.
Description
technical field [0001] The technical field of practical automated testing, more specifically, relates to an ICT expansion fixture and a testing method for testing the number of pin points on a PCBA board. Background technique [0002] ICT equipment, namely In Circuit Tester, is a common test equipment for electronics companies. It cooperates with the fixture to detect the PCBA board produced by the enterprise, and can distinguish the components on the PCBA board, the defects of the circuit in the PCB, and various defects caused by the process. Traditional ICT equipment has a fixed number of test pins. When the number of pin points that PCBA needs to test does not exceed the test points of ICT equipment, fixtures can be made normally according to requirements to test PCBA boards. However, when the number of pin points to be tested on the PCBA board to be tested is greater than the number of ICT equipment test points, the excess portion of the pin points to be tested cannot b...
