HAST (Highly Accelerated Stress Test) chambers reduce the time it takes to complete humidity testing for semiconductors. By elevating temperatures above 100°C and increasing the pressure, simulation of normal humidity tests can be made while maintaining the same failure mechanisms. Tests can be completed in days, not weeks. Our HAST systems have a modern design that's easier to use:

• Automatic humidity filling
• Automatic door lock
• A round workspace, allowing wider sample boards to be loaded
• Convenient, hermetic power-pin system for bias testing

We now offer an "Air HAST" modification for faster testing of lead-free solder whisker resistance to humidity.

Ideal for an array of industries including: 

• • • Automotive Electronics & EV Systems
      Modern vehicles are data centers-on-wheels- ECUs, sensors, battery management systems (BMS), and power modules all demand bulletproof reliability under extreme humidity, heat, and vibration. HAST can validate sealing, detect moisture intrusion, and accelerate aging to ensure safety and durability.
    • Aerospace & Defense
      Avionics, satellite hardware, and rugged aerospace components operate under intense pressure, humidity, and thermal stress. HAST testing provides rapid reliability insights, mitigating costly failures and enabling rapid design iteration.
    • Medical Devices & Sterile Equipment
      Devices exposed to autoclaving, steam sterilization, or high humidity environments, like surgical instruments, implants, and diagnostic sensors- must withstand repeated cycles without degradation. HAST offers quick, predictive validation of materials and seals.
    • Consumer Electronics & Wearables
      Think smartphones, laptops, IoT wearables. These gadgets face moisture, sweat, carry-case condensation, or even accidental immersion. Testing enclosure integrity and PCB resilience in rapid time is a competitive edge.
    • Adhesives, Coatings & Materials (Construction, Marine)
      HAST accelerates degradation of coatings, adhesives, and polymer systems- perfect for validating outdoor materials used in construction, marine, and industrial environments prone to moisture ingress, corrosion, or delamination.
    • Battery & Energy Storage Testing

With the rise of EVs and renewable infrastructure, batteries are under extreme scrutiny. Customized HAST chambers- even with explosion-proof features- can simulate thermal abuse, humidity cycles, and pressure stress for cell and pack reliability testing.
