Environmental test chambers is used in the test of AEC-Q100 automotive electronic parts

The environmental test chambers is applied to the AEC-Q100 test standard for automotive electronic components testing. Automotive electronic components are divided into three categories, including IC, discrete semiconductors, and passive components. In order to ensure that these automotive electronic components meet automotive safety requirements The highest standard, the American Automotive Electronics Council (AEC, Automotive Electronics Council) is a set of standards designed for active parts [microcontrollers and integrated circuits.. etc.] [AEC-Q100], designed for passive components [[AEC-Q200], which regulates the product quality and reliability that must be achieved by passive components. AEC-Q100 is the automotive reliability test standard established by the AEC organization.
