High Accelerated Stress Test (HAST)

Equipment: HAST Chamber

Working Principle

  • Stress the DUT by increasing the amount of water vapor, pressure and temperature
  • Simulates the conditions inside the chamber
  • An alternative of damp heat and Pressure Coker Test (PCT)
  • Standard: IEC 60068-2-67

Technical Information

  • Effectiveness of qualification test
  • Plastic-sealed components test
  • Module connection failures
  • Understand the degradation of DUT
