What is AEC-Q103 Certification?

What is AEC-Q103?  

AEC-Q103 is a certification standard for stress testing of automotive sensors based on failure mechanisms. Microelectromechanical systems (MEMS) involve a variety of disciplines and technologies, including electronics, mechanics, materials science, physics, chemistry, biology, and medicine, with broad application prospects. MEMS enables sensors to become smaller and smarter, making MEMS sensors highly promising in the era of smart industry.  

AEC-Q103-002 targets MEMS pressure sensors, while AEC-Q103-003 focuses on MEMS microphone devices. The release of these two standards provides more specific requirements for the industry, making automotive-grade certification for MEMS more reasonable.  

China's JJR Laboratory is qualified and equipped to perform AEC-Q103 Certification testing. It offers services for automotive-grade MEMS sensor AEC-Q103 certification and AEC-Q103 testing.
