Under the design strength limit, the product uses the temperature acceleration technique (the product produces alternating expansion and contraction when circulating in the upper and lower extreme temperatures) to change the external environmental stress, causing thermal stress and strain in the product, and through the accelerated stress. In order to make the potential parts of the product appear in the product, process defects, process defects, to avoid the product in the process of use, due to environmental stress test failure, resulting in unnecessary losses, improve product shipments The rate has a significant effect on reducing the number of repairs. In addition, the stress screen itself is a process stage process, not a reliability test, so stress screening is a 100% procedure for the product.
