TEST FIXTURE AND METHOD FOR CIRCUIT BOARD TESTING

摘要

A Printed Circuit Board 18 (PCB) test fixture includes flex sensors 12 for monitoring the flex (or distortion) of the PCB 18 during testing. The PCB 18 is positioned above irregular array of test probes 24. The test probes 24 are aligned with electrical test points on the PCB 18. The PCB 18 is then pressed downward against the test probes 24 by an irregular array of pushers 16. The positions of the pushers 16 are generally specified by a PCB manufacturer to avoid PCB elements and the positions of the test probes 24 are generally specified by the PCB manufacturer to obtain desired signals.
