Testing system and testing method of flexible circuit board

Abstract

The invention provides a testing system and a testing method for a flexible circuit board. The testing system comprises a jig, a switching device, a supporting frame and a testing device. A probe A is fixedly embedded into a penetrating hole A, the bottom end of the probe A protrudes out of the bottom face of a first fixing plate, and the top end of the probe A movably penetrates through a second probe A movable through hole and a first probe A movable through hole upwards in sequence; an FPC is placed in an FPC containing groove; and the probe A is directly connected and conducted with a contact A on the FPC, so that the contact on the FPC can be directly tested without switching test, and the test precision is higher.

Description

technical field [0001] The invention relates to the field of flexible circuit board testing, in particular to a testing system and a testing method for a flexible circuit board. Background technique [0002] Flexible circuit board is a kind of highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has high wiring density, light weight, thin thickness, bending In the process of producing flexible circuit boards, in order to ensure that the produced flexible circuit boards are qualified, it is necessary to test each flexible circuit board with a testing device. [0003] The defective of prior art mainly shows in: [0004] 1. The existing FPC test uses a circuit adapter board to transfer the FPC contacts to the adapter board, and then use the probe to test the contacts on the adapter board, and the contacts on the adapter board are only analog contacts. Because the contact size of the adapter board is much lar...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing FPC test uses a circuit adapter board to transfer the FPC contacts to the adapter board, and then use the probe to test the contacts on the adapter board, and the contacts on the adapter board are only analog contacts. Because the contact size of the adapter board is much larger than that of the FPC itself, the portability of the test is greatly improved, but the test accuracy is also reduced, and there is a transfer impedance on the adapter board, which affects the test results;

[0005] 2. Existing FPC test equipment uses fixed probes to match the principle of test fixtures. In the rapidly changing FPC product market, it cannot be flexibly compatible with the updated form of FPC and reduce the cost of test transformation.
