HAST Accelerated Life Test Machine(Extreme Humidity Test Chamber)

HAST Accelerated Life Test Machine


HAST accelerated life test machine(Extreme humidity test chamber) is designed to speed up the test process and shorten the life test time of the product or system under high environmental stress (such as temperature) and working stress (voltage, load, etc. applied to the product). With the improvement of semiconductor reliability, most of the former semiconductor devices can withstand the long-term THB test without failure, so the test time for determining the quality of the finished product is also increased accordingly. In order to improve the test efficiency and reduce the time, the latest is adopted.
