Overview
Every chip is tested electrically, first on the wafer through a probe card and again after packaging in a handler. Reliability tests such as burn-in, HAST and thermal cycling then show whether a design and package will survive years of use.
Japanese suppliers cover the whole chain: high-end testers, testers for discrete and power devices, handlers that sort finished devices, probe cards, burn-in boards and test chambers.
