Environmental Stress Screening (ESS)

Reliable testing to guarantee safety

High product reliability is a basic requirement for today’s competitive market and is often the only difference between the various manufacturers. The reliability of electronic prod ucts can be substantially improved by the use of environmental stress screening (ESS) techniques to minimize the risk of errors and failures of products and simultaneously im prove the reputation of a company.

The ESS test

During the ESS test, the products are subject to precisely defined stress so that defects in components and PCBs can be detected before leaving the manufacturer’s plant. Detecting weak points considerably improves the robustness of the products. Unreliable systems are filtered out before they reach the customers. Each product requires a specially adapted ESS technique.
