Environment is the primary factor affecting product reliability index,and the environmental factor that has the greatest impact on electronic products is high temperature.The high temperature environment will first make the temperature appreciation of electronic products reach a higher level,so that the product will fail in a shorter period of time,and then the end of life.To ensure that any electronic product can be used normally under its specified high temperature conditions,it is necessary to carry out the corresponding high temperature environment test to determine the suitability of the product for storage and use in a high temperature environment.This paper first introduces the effect of high temperature environment on products and what failure modes will be caused.Then,the corresponding standards and the test items and index requirements specified in the standards are introduced to ensure that the products meet the application in the high temperature environment.At the same time,the general design method to ensure the high temperature conformity of the product is introduced.Through the influence analysis of high temperature environment,standard requirements and general design methods,the applicability and testing of products in high temperature environment are provided.
