Semiconductor devices. Mechanical and climatic test methods - Accelerated moisture resistance. Unbiased HAST1 Scope and object The unbiased highly accelerated stress testing (HAST) is performed for the purpose of evaluating the reliability of non hermetically packaged solid state devices in humid environments. It is a highly accelerated test which employs temperature and humidity under non condensing conditions to accelerate the penetration of moisture through the external protective material (encapsulant or seal) or along the interface between the external
