The invention discloses a positioning jig for a PCB, and the jig comprises a top layer, a second top layer, a third top layer, a central layer and a basic layer, and also comprises two angle-shaped positioning blocks and four pilot pin columns, wherein the top layer, the second top layer, the third top layer, the central layer and the basic layer are sequentially stacked from the top to the bottom. The two angle-shaped positioning blocks and the four pilot pin columns pass through the through holes of the top layer and the second top layer, and are fixed on the third top layer. The angle-shaped positioning blocks are shaped like L, and are symmetrically distributed on one diagonal line of the top layer. The four pilot pin columns are distributed in four directions of the top layer in a manner that each two of four pilot pin columns are symmetric. Two corners of the PCB along the diagonal angle are limited by the two angle-shaped positioning blocks, and four side edges of the PCB are limited by the four pilot pin columns. The jig is simple in structure, is low in cost, can achieve the accurate positioning of the PCB without a positioning hole, performs the electrical testing of thePCB, and improves the applicability and the testing efficiency of the PCB.
Description
technical field [0001] The invention relates to the technical field of PCB electric measuring equipment, in particular to a positioning jig applied to a PCB board. Background technique [0002] The traditional PCB (printed circuit board) test method is to use the manipulator of the electrical test product to grab the PCB that needs to be tested and place it on the test fixture, and the test fixture has guide pins corresponding to the holes on the PCB board to ensure After the test fixture and the PCB board are pressed together, the probes of the fixture correspond to the PCB-Pad (pad) one by one, so as to ensure a high pass rate of the PASS power amplifier board in the electrical testing process. [0003] In the application process of the jig, the positioning in the jig, the matching of the guide pin and the positioning hole of the PCB are the fundamentals of the whole process, and the testing efficiency will be low if the positioning is not accurate. [0004] In the proces...
