HAST Chamber

KOMEG Highly Accelerated Stress Test (HAST) Chambers are engineered to accelerate moisture-resistance and long-term reliability testing for semiconductors, integrated circuits (ICs), microelectronic devices, electronic components, advanced packaging materials, and other moisture-sensitive products.

By combining high temperature, high humidity, and elevated pressure in a precisely controlled saturated steam environment, the chamber rapidly accelerates moisture penetration, corrosion, insulation degradation, delamination, and other failure mechanisms that may occur during a product’s service life. This enables manufacturers to identify hidden defects, validate product reliability, and significantly shorten development and qualification cycles.

The KOMEG HAST Chamber supports standard saturated HAST (PCT) and unsaturated HAST (UHAST) testing modes. The standard operating temperature ranges from +105°C to +135°C, with optional configurations up to +145°C and customizable solutions reaching +162.5°C. Relative humidity can be controlled from 65%RH to 100%RH in unsaturated mode or maintained at 100%RH in saturated mode, while the pressure range extends from 100 kPa to 300 kPa (absolute pressure), providing stable and repeatable accelerated aging conditions for a wide variety of reliability tests.

Designed for long-term laboratory operation, the chamber features a double-layer cylindrical pressure vessel manufactured from SUS316 stainless steel, a high-efficiency vacuum system for generating pure saturated steam, and an optimized chamber structure that minimizes condensation droplets from directly contacting test specimens, ensuring more accurate and repeatable test results.

To ensure safe operation under high-temperature and high-pressure conditions, the chamber is equipped with comprehensive protection systems, including over-temperature protection, over-pressure protection, door interlock protection, water shortage detection, leakage protection, overload protection, and automatic alarm functions.

Widely used in semiconductor manufacturing, automotive electronics, consumer electronics, telecommunications, aerospace, medical devices, and research laboratories, KOMEG HAST Chambers comply with internationally recognized reliability testing standards such as JESD22-A102, providing engineers with accurate, repeatable, and efficient accelerated reliability testing solutions.
