Automotive electronics mainly take the International Automotive Electronics Committee (AEC) as the verification standard of vehicle regulations, including AEC-Q 100 (integrated circuit IC), AEC-Q10/(discrete components) and AEC-Q 102 (discrete photoelectric LED).
Chrysler, Ford and General Motors set up the Automotive Electronics Committee (AEC) to establish a set of universal parts qualification and quality system standards, which is a group established by major American automobile manufacturers and major parts manufacturers to standardize the reliability and certification standards of automotive electronic parts.
Because all the parts that meet AEC specifications can be adopted by the above three car factories at the same time, this promotes the willingness of parts manufacturers to exchange their product characteristic data, promotes the realization of universality of automobile parts, and lays the foundation for the rapid growth of automobile parts market.
The main automotive electronic members are Autoliv, Continental, Delphi, Johnson Controls and Visteon.
AEC-Q certification test content:
1, accelerate the environmental pressure test.
2. Accelerated life simulation test
3. Reliability testing
4, electrical characteristics confirmation test
5. Sealing test
6, screening monitoring test
7. Destructive physical analysis
Extended data
With the development of multi-function of on-board application equipment and the popularization of hybrid electric vehicles and electric vehicles, new uses such as power monitoring function are constantly expanding, and the requirements for miniaturization and high reliability of vehicle parts under high temperature environment conditions (-40 ~+ 125℃, -55℃~ 175℃) are getting higher and higher.
A car is made up of many parts, but all of them are closely related to the safety of driving, so every part should be required to achieve the highest quality and reliability, even the ideal state of zero defects. Therefore, in the automobile industry, the importance of quality control of automobile parts is often higher than the functionality of parts.
The stress in AEC-Q200 specification includes temperature stress, electrical pressure, mechanical force and so on, all in order to see whether these devices can withstand the severe test of vehicle environment. Only the equipment that has passed all inspections can be declared to meet the requirements of AEC-Q200.
There is no review mechanism in AEC specifications. Manufacturers need to manage the quality of their products according to AEC specifications and complete the experiments to get the experimental results, and then declare that their products have passed AEC certification by self-declaration. The end customer can conduct spot check or verification according to the contents of the report to see if it really meets the specifications.
If customers want, they can also buy your products without AEC certification and AEC restrictions, but in fact, such devices will be tested more strictly because the manufacturers' own standards will be stricter than AEC standards.
