Highly Accelerated Stress Screening (HASS), a quality assurance procedure based on HALT (Highly Accelerated Life Testing) principles, is a universally applicable technology. It detects defects in manufacturing and process variations that can cause early failures in the field. Highly Accelerated Stress Screening is widely used in diverse industries, including military, medical devices, and aerospace. MaTestLab, a leading testing service provider with a vast network of testing laboratories in the USA, is well-equipped to conduct HASS tests for our clients.
Principle and Methodology of HASS
HASS, a proactive technology, applies stress beyond normal operating conditions for the identification of potential weaknesses by accelerating the time-to-failure. Its methodology involves the application of stress, stress profile, monitoring, failure analysis, and corrective actions. The procedure involves the application of mechanical, thermal, and electrical stresses. Pre-defined stress profiles are used for continuous monitoring of product performance, failure modes and root causes are detected, and processes are designed to address found flaws.
Instrumentation
Environmental chambers for rapid thermal cycling, vibration tables for real-world mechanical stresses, electrical test equipment for monitoring parameters, and data acquisition systems for recording and analyzing stress-induced performance metrics are instruments used in Highly Accelerated Stress Screening.

Applications of HASS
HASS is widely used to ensure the reliability of critical components, test electronic control units, verify the durability of life-supporting equipment, and enhance the robustness of gadgets in different fields, such as automotive, aerospace, consumer electronics, medical devices, and military.
