Abstract
This paper introduces a practical test method that combines statistics with a contactless test approach. Experiments using real PCBs show the effectiveness of the method, where significant z-scores are obtained to discriminate defective interconnects. The studied test cases involve conventional Printed Circuit Boards (PCBs) with Ball Grid Array (BGA) packages and open sockets.
