HAST Highly Accelerated Stress Test Chamber

Short Description:

The HAST Highly Accelerated Stress Test Chamber is designed to accelerate the exposure of potential reliability weaknesses in electronic and industrial products by combining elevated temperature, humidity, and pressure.

The chamber is suitable for testing electronic components, PCBs, multilayer PCBs, ICs, LCDs, automotive components, plastics, magnets, lighting products, and other sealed or moisture-sensitive products.

With a temperature range of 105–155°C, adjustable humidity from 65–100% RH, and pressure from approximately 0.2–3.5 kg/cm² gauge pressure, the system provides an accelerated environmental stress condition for reliability evaluation.
