Two new techniques for identifying opens on printed circuit boards: analog, junction test, and radio frequency induction test

摘要

This session describes the principles, implementation, strengths, weaknesses and applications of two vectorless test techniques developed by Teradyne, and currently in use on Teradyne board test equipment. The goal of this session is for a practicing test engineer or test manager to understand how these techniques work, how to apply them against different test problems, and how to use them as part of an overall test strategy. Examples drawn from Users' experience demonstrate how vectorless testing can dramatically reduce test cost and cycle time while maintaining or improving fault coverage.
