Abstract

Beginning in August 1989, an automated assembly pager production line began experiencing a massive product failure rate for page sensitivity and intermediate frequency shifting out of specification at the customer quality audit (CQA). Also, an increased fallout at final test automated tuning had been observed, the failure mode being traced to the inability to automatically tune the trimmer capacitors utilized on the receiver assemblies.
