Highly accelerated stress testing, commonly abbreviated HAST, combines elevated temperature and humidity with a pressurized environment to investigate moisture-related reliability concerns. It is used for suitable electronic components, packages and materials under a defined test procedure.
The exposure accelerates selected mechanisms, but the result must be interpreted in relation to the sample and the test conditions. Biased and unbiased procedures address different requirements. Electrical connections and monitoring need to match the intended method when a device is powered during testing.
Compare usable chamber space, temperature and humidity capabilities, pressure control and sample-loading arrangements. Condensation management and the transitions into and out of the test are important for maintaining the specified exposure. Records of conditions and device behavior help analysts distinguish a meaningful failure from a setup problem.
