    Highly Accelerated Stress Test – HAST Testing Services

    A highly accelerated stress test (HAST) is an essential part of environmental testing that combines high-temperature, high-humidity, pressure, and time to test a component’s reliability under harsh environments. It is an efficient and faster alternative to traditional temperature-humidity testing for testing moisture penetration in semiconductors, thin-film resistors, solar panels, pharmaceutical products, etc. to reveal corrosion failures due to packaging, materials, seals, and joints. The higher stressors and pressure better simulate the effects of humidity and temperature and help predict component failures within days. HAST testing is also used in transportation, packaging, and shelf-life studies of products. HAST tests under the same temperature, humidity, and pressure variables are performed with voltage bias (BHAST) to accelerate moisture penetration and related induced failures within the device or product.
