TESTING DEVICE FOR BOTH-SIDED TWO-STAGE CONTACTING OF EQUIPPED PRINTED CIRCUIT BOARDS

摘要

A testing device for both-sided two-stage contacting of equipped printed circuit boards. A lower needle adaptor has first and second resilient or spring-seated contact needles of different lengths and an upper needle adaptor has third and fourth resilient or spring-seated contact needles also differing in length, which are provided for both-sided, two-stage contacting of component equipped printed circuit boards. In all stages of the contacting, the printed circuit boards are firmly clamped between lower and upper pressure rams arranged test-specimen-associated. The testing device provides a high contacting reliability.
