Highly Accelerated Stress Screening Optimization

Highly Accelerated Stress Screening Optimization

Highly Accelerated Stress Screening (HASS) a popular method used by many manufacturing facilities to screen process defects. HASS testing comprises of two phases – (i) precipitation and (ii) detection. The detection includes a functional test at various temperature values and vibration test at 6-deg...
