AEC Q200 test conditions
Mar 28, 2018

Note: The environmental test conditions of the AEC-Q200 are mainly based on the MIL-STD-202 and JEDEC22A-104 specifications. The test temperatures of different parts are not only the same, but also the power supply (voltage, current, and load) requirements. It will be different, high temperature storage is not applied bias and load, but in the high temperature working life needs, temperature cycle and temperature impact, the test purpose and method is not the same, in the temperature cycle, high temperature changes need to control the temperature change rate, Temperature shock is not used, high humidity is commonly known as high temperature and humidity test, and humidity resistance is wet freeze test.
