Environmental Stress Screen is a means of screening electronic assemblies at the most cost-effective point of manufacture to expose defects that can't be detected by visual inspection or electricaltesting. These defects are typically related to defective parts or workmanship and are normally found as early field failures.
ESS works by subjecting 100% of a group of products to an environmental stimulus or a set of stimuli for a predetermined time for the purpose of forcing failures to occur before shipment, in fact, at the board level.
Failures are normal and expected when ESS is applied. This makes ESS radically different than more conventional certification testing which requires failure free operation as proof of reliability.
ESS is not a test, it is a process.
Expected benefits of a properly applied ESS program are:
1. Reduced field repair expense
2. Fewer defects and waste
3. Elimination of less effective screening-procedures
4. Lower unit cost
5. Increased product value
6. Improved customer satisfaction
7. Better return on investment
