Abstract

The invention relates to a modular PCB testing jig. The modular PCB testing jig comprises a testing module, a pin plate module, a supporting plate module and a covering plate module. The testing module comprises a testing platform, a support, a counter, a control board and a testing instrument. The pin plate module comprises a base, a pin plate, a sponge pad and a lower surrounding frame, wherein detection pins, spacers and springs are arranged on the pin plate, the base plate is provided with an air exhaust hole communicated with a vacuum extraction assembly, and the lower surrounding frame and the pin plate form a first containing cavity. The supporting plate module comprises a supporting plate, a sponge pad, a counter contact, an upper surrounding frame assembly, wherein the supporting plate is arranged in the first containing cavity, the upper surrounding frame assembly and the supporting plate define a second containing cavity for containing a PCB, and the supporting plate is provided with pin holes. The upper end faces of the pin plate and the supporting plate are both provided with a layer of copper foil. The covering plate module comprises an air cylinder and a cover plate fixed to a piston rod of the air cylinder, and pressing rods and a counter contact touch pin are arranged at the lower end of the cover plate. The modular PCB testing jig is compact in structure, convenient to maintain, accurate in test, high in automatic degree and capable of meeting the demand for large-scale test.

Description

technical field [0001] The invention relates to a PCB board test fixture, in particular to a modularized PCB board test fixture. Background technique [0002] PCB board is an important electronic component and a carrier of electronic components. Before the produced PCB board is put into use, it needs to be tested for function and performance. PCB board test fixture is a test equipment for testing the electrical performance and electrical connection of components on the PCB, so as to check out manufacturing defects and defective components. Existing PCB board testing fixtures have complex structures, difficult operation and maintenance, long testing process, and low production efficiency, which cannot meet the needs of large-scale testing. Contents of the invention [0003] In order to solve the above problems, the present invention provides a modular PCB board test fixture, each part has clear functions and a compact structure. The maintenance is simple, the operation ...
