HAST Chambers

Compressing standard 1,000-hour damp heat evaluations into a precise 96-hour window, Sanwood HAST systems utilize unsaturated steam pressure to isolate latent moisture-resistance vulnerabilities across advanced IC packages and wide-bandgap substrates.

This specialized environmental simulation platform operates at severe thermodynamic limits—maintaining precise control up to 142℃, 85% RH, and 0.41 MPa non-condensing vapor pressure—to force moisture penetration through protective passivation layers without causing artificial surface pooling. By rapidly triggering localized electrochemical migration, galvanic corrosion, and micro-leakage failures on an accelerated timeline, this instrumentation delivers definitive reliability data in absolute alignment with JEDEC JESD22-A110, A118, and IEC certification standards.

Highly Accelerated Stress Test System (HAST Chamber)

Evaluating the long-term moisture resistance of non-hermetic semiconductor packagings via traditional Temperature Humidity Bias (THB) testing demands an inefficient 1000-hour operational cycle, severely bottlenecking product time-to-market. S

anwood's Highly Accelerated Stress Test System (HAST Chamber) shatters this validation latency. By jacking up ambient pressure up to 4 atmospheres and raising temperatures to 145℃ within a certified containment shell, it accelerates water vapor penetration exponentially. Functioning as a highly specialized environmental test chamber and precise climatic test chamber, the system enforces strict, dynamic ...
