Environmental stress screening refers to the process of exposing a newly manufactured engineering product or component to stresses such as heat and vibration in order to force defective examples to fail and therefore weed them out of the population that is sold or delivered for use. It is widely used in military and aerospace applications, less so for commercial products. The tests need not be elaborate, for example, switching an electronic or electrical system on and off a few times may be enough to catch some simple defects that would otherwise be encountered by the end user very soon after the product was first used.
Electronic Stress Screening (ESS)
The stress screening from this process will help find infant mortality in the product. Finding these failures before the product reaches the customer yields better quality, lower warranty expenses, and happier customers. Tests may include the following:
- Temperature variations
- Vibration tests
- Pressure
- Flexibility tests
