Advanced Techniques for Optimization of Board Test Because of the increasing complexity of electronic circuits and boards, testing is becoming one of the most important aspects before and after the production cycle, in order to guarantee day by day the quality and reliability of the product. Since a comprehensive and in-depth test could require sometimes an excessive amount of time, is crucial to develop techniques that aim to optimize the process in a smart way. The solution for a printed circuit board test is to use the bed of nails or the flying probes architecture. Two major fields of the latter case, regarding real testing application, have been here deepen and analyzed, and then presented developed algorithms that can solve or optimize some issues that occur in the case of flying probes in-circuit testers.
