High Ramp Rate ESS Test Chamber For Environmental Stress Screening Test
What is an ESS CHAMBER ?
Environmental Stress Screening (ESS), also known as AST (Accelerated Stress Testing), HALT (Highly Accelerated Stress Test), HASS (Highly Accelerated Stress Screening) or Burn-in test.
Developed to help electronics manufacturers detect product defects and production flaws, ESS test is widely used in military and aerospace applications, and also for commercial products. ESS can be performed as part of the manufacturing process or it can be used in new product qualification testing. Tests typically include the following:
- Temperature variations
- Vibration tests
- Pressure
- Flexibility tests
