Verification requirements and importance of AEC-Q101 certification testing for automotive IGBT modules

Date:2024-05-31 11:45:09Views:34

With the continuous development of automotive electronic technology, electronic components inside cars have become increasingly important. Among them, the automotive IGBT module, as a key power electronic device, plays an important role in controlling electric motors, frequency converters, and other high-power applications. To ensure the stable and reliable operation of automotive IGBT modules in harsh automotive environments, AEC-Q101 certification testing and verification have become an essential step.

AEC-Q101 certification testing verification is a strict quality standard for automotive electronic components developed by the International Automotive Electronics Council (IAEC). The purpose of this certification test verification is to ensure that automotive electronic components can meet the requirements of the automotive industry under various extreme conditions, including high temperature, low temperature, humidity, vibration, etc. For automotive IGBT modules, passing AEC-Q101 certification testing verification can ensure their reliability and stability during vehicle use.

The AEC-Q101 certification testing verification requirements cover multiple aspects. Firstly, temperature cycling testing is one of them. This test requires the IGBT module to be cycled multiple times between high and low temperatures to simulate the working environment of the car under different climate conditions. This can verify the performance stability and reliability of the module under temperature changes.

Secondly, humidity cycle testing is also an essential test. The operation of automotive IGBT modules in humid environments may lead to issues such as moisture erosion and electrical short circuits. Through humidity cycle testing, the corrosion resistance and electrical performance of the module in humid environments can be verified.

In addition, vibration and impact testing are also important parts of AEC-Q101 certification testing verification. During the driving process of a car, it will be affected by various road conditions, including bumps, vibrations, and impacts. Therefore, automotive IGBT modules need to withstand these challenges to ensure reliability and stability in vibration and impact environments.

Summary, AEC-Q101 certification testing verification is crucial for ensuring the quality of automotive IGBT modules. Through these tests, the reliability and stability of the module under various extreme conditions can be ensured, and the performance and safety of the automotive system can be improved. Automobile manufacturers and suppliers should strictly follow the testing and verification requirements of AEC-Q101 certification to ensure that the IGBT modules used comply with automotive industry standards, thereby providing consumers with more reliable automotive products.
