| Abstract: | Environmental Stress Screening （ ESS ） has been widely used in avionics industry. ESS plays a key role in ensuring the reliability of products by reducing the number of infant mortality types of failures. With the development of the electronic industry, ESS is facing new challenges, so improvement should be made to enhance the ESS effectiveness. The paper presents the ESS stress mechanism and the way to improve ESS process to achieve higher reliability. |
