It is suitable for cold resistance testing, adaptability testing under rapid or gradual temperature changes of electrical and electronic products and their components, especially for conducting Environmental Stress Screening (ESS) tests on electrical and electronic products.

The use of temperature acceleration techniques (cycle testing within the upper and lower limits of machine temperature, alternating expansion and contraction of the product) generates thermal stress and strain. By accelerating the stress, potential defects in the product (material defects, process defects, process defects) are exposed to prevent the product from being tested by environmental stress during use and causing failure. This has a significant effect on improving product delivery yield and reducing the number of repairs.
