Highly Accelerated Stress Test (HAST) Laboratory 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.

Humidity Testing
Humidity Testing is a suite of standardized environmental tests performed to evaluate the prolonged effect of humidity on a product or material.
Vibration Testing
Vibration testing is the process of evaluating the performance or degradation of a product, component, system, or structure when subjected to mechanical motion.
Accelerated Aging
Accelerated aging is the expedited aging process of a product by subjecting it to aggravated operational and environmental conditions like temperature, pressure, humidity, light, vibration, etc.
