CDM Test for Low Humidity Environment Compatibility

Achieving humidity below 30% with dry air! Introducing the humidity requirements and specifications of key standards in CDM testing.

In ANSI/ESDA/JEDEC JS-002-2014, it is required that the relative humidity near the device during testing be kept below 30%. The verification method involves installing temperature and humidity sensors in two locations near the sample to continuously monitor the temperature and humidity, and the test begins when the relative humidity falls below 30%. The AEC standards also explicitly state in the 2019 revision that they comply with ANSI/ESDA/JEDEC JS-002, and it is expected that the demand for low humidity environments will continue to increase in the future. 【Humidity Requirements for Major CDM Test Standards】 ■ ANSI/ESDA/JEDEC JS-002-2018: Relative humidity below 30% ■ AEC-Q100-011 Rev-D・AEC-Q101-005 Rev-A: Relative humidity below 30% ■ JEITA ED-4701/302A (Test Method 305D): Ambient temperature 25°C ± 5°C *For more details, please refer to the PDF document or feel free to contact us.
