Fpc soft board test

There are four types of FPC: single board and double board, multilayer flexible board and rigid flexible board. It is mainly made of polyimide or polyester film, and other components are insulating film, conductor and adhesive.

FPC needs pretreatment before production. In the production process, it is necessary to pack and ship after the final inspection. FPC flexible circuit testing;

1. Thermal stress test-verify the heat resistance of FPC

2. Half-court adhesion test-verify whether FPC eats tin well.

3. Environmental test-verify whether FPC can maintain good performance in the environment with rapid temperature change.

4. Electroplating adhesion test-verify whether the adhesion of FPC coating is good.

5. Winding test-verify whether the bending angle of FPC can maintain good performance.

With the help of the elastic microneedle module, the flexible printed circuit board test of FPC can be realized, which is beneficial to improve the test efficiency and reduce the production cost. In high current transmission, it can carry current as high as 50A, and the minimum response value in small pitch field can reach 0.15 mm. Needless to say, the connection is stable and reliable, with an average service life of more than 20w times and high adaptability.
