Abstract：In the development and production of electronic products，it is an effective and important measure to improve product quality and reliability to eliminate the early failure of products through environmental stress screening test. This paper introduces the concept of environmental stress screening for electronic products，analyzes and studies the test methods of conventional environmental stress screening and typical environmental stress screening. Meanwhile，by exploring the influence of temperature change rate on temperature cycle screening degree，an improved scheme of environmental stress screening is proposed，which can effectively improve the efficiency of environmental stress screening and has a high popularization value.
Keywords：environmental stress screening；temperature cycling；rate of temperature change
