DETECTION OF PRECOCED FAILURES IN PRINTED CIRCUIT BOARDS

摘要

A method includes characterizing the effects of an electric field on a first set of printed circuit boards (PWBs) by testing the first set of PWBs to generate test data, using the test data to determine a life curve. dielectric of the first set of PWB, and based on the dielectric life curve, defining a selection time and a selection voltage to protect premature failures in a second set of PWB due to electric fields.
