Environmental Stress Screening (ESS)
Environmental Stress Screening (ESS) is a testing process for electronic products designed to expose weak components and process defects for correction. This testing typically involves applying environmental stresses, such as temperature cycling and random vibration, to induce latent defects, thereby weeding out early-failure products before they enter the market and improving the overall reliability of the product.
We have various models of high and low-temperature test chambers and vibration test systems, with the largest being a 25m³ three-in-one environmental test system equipped with a 40T (392 kN) shaker. For clients requiring larger systems, we can temporarily assemble up to a 40m³ system with a 60T (588 kN) shaker (internal dimensions 3,300mm×3,300mm×2,200mm). We are also equipped with high-power adjustable AC/DC power supplies and high-power resistive-inductive loads to meet the needs of applying electrical stress and operating under load during testing. Our stress screening equipment is characterized by its large quantity and large volume, which can meet the typical high-volume sample requirements of stress screening tests.
