HAST (Highly Accelerated Stress Testing) chamber ETSP- HAST series
ETSP-HAST series are “Highly Accelerated Temperature/Humidity Stress Test”. It was developed as a shorter alternative to Temperature Humidity Bias (THB) testing.
If THB testing takes 1000 hours to complete, HAST results are available within 96~ 100 hours.
HAST accelerates corrosion, particularly that of the die metal lines and thin film resistors. HAST requires preconditioning and is conducted with electrical bias at 130℃ and 85%RH for 96~100 hours.
- Unsaturated or saturated humidity control
