Tests, inspections or combination thereof, imposed on 100% of parts to remove unsatisfactory items or those likely to exhibit early failures. Using stress testing, defects are weeded out in a product where the root causes cannot be eliminated. Removing all the defective parts (infant mortality) brings the lot to the constant failure rate (working life) phase. The screening does not increase the reliability of the components but removes those showing weakness or defects. Tests, inspections or combination thereof, imposed on 100% of parts to remove unsatisfactory items or those likely to exhibit early failures.

The aim of the external inspection of coated PCA is to determine if all the surfaces and devices are adequately covered. In order to make easy such inspection, fluorescing agents can be added to the polymeric formulation, which shows a blue glow when the PCA is exposed to ultraviolet (UV) light.

Life test is an electrical stress test that typically employs voltage and/or temperature to accelerate the appearance of wear-out reliability failures in a device. The objective of life testing is to evaluate whether failures caused by wear-out are likely to occur during the product lifetime and thus to estimate compliance of the device with the long-term reliability requirements
