Detailed explanation of the definition domain standards of automotive grade

The formulation organization and main standards of automotive grade standards

The international Automotive Electronics Council (AEC) plays a central role in the development of automotive-grade standards. AEC was co-founded by leading companies such as Chrysler, Ford, and General Motors to establish universal automotive parts certification and quality system standards. It has developed the AEC-Q series of standards, including AEC-Q100, AEC-Q101, etc., which detail the reliability testing requirements for automotive electronic components to ensure that they can work stably in harsh automotive environments. AEC's standardization work has not only improved the performance of automotive electronic components, but also promoted the versatility of automotive parts, laying a solid foundation for the healthy development of the automotive industry.

The AEC-Q series of standards is a set of automotive component and product verification standards developed by the International Automotive Electronics Council (AEC) to ensure the reliability and consistency of automotive electronic components to meet the high requirements of the automotive industry. This series of standards covers several major categories. The following is a detailed introduction to AEC-Q100, AEC-Q101 and AEC-Q102:

1. AEC-Q100: This is one of the most basic and important standards in the AEC-Q series, mainly for components such as integrated circuits ( ICs ) and microcontrollers . The AEC-Q100 standard focuses on the temperature characteristics and electrical characteristics of components, requiring components to work normally in extremely high and low temperature environments and withstand various electrical performance tests. In addition, AEC-Q100 also specifies the voltage tolerance of components in human body discharge mode (HBM) and charged device mode (CDM).

2. AEC-Q101: This is a test standard for automotive discrete devices, mainly applicable to the standard specifications of automotive discrete devices and components. AEC-Q101 requires components to pass stress testing to provide a certain level of quality and reliability. The standard defines the lower stress test requirements for discrete semiconductor components (such as transistors , diodes , etc.) and provides corresponding reference test conditions. AEC-Q101 also establishes three levels of judgment standards based on different components to ensure the stable performance of components in various environments.

3. AEC-Q102: This is a comprehensive reliability test certification standard for automotive optoelectronic devices . The AEC-Q102 standard defines the minimum stress test requirements and test conditions for all discrete optoelectronic semiconductor components (currently mainly LEDs ) used inside and outside automotive electronics. Each test is designed for the harsh environment that automotive optoelectronic devices may be subjected to in order to protect safety during driving. The AEC-Q102 standard is mainly applicable to a variety of optoelectronic devices such as LEDs, laser components, and photodiodes.

The AEC-Q100 standard plays an important role in the field of automotive electronic components. It is divided into four levels (0, 1, 2, 3) according to the operating temperature. Among them, the highest level 0 product can operate stably at extreme temperatures of -40℃ to 150℃, ensuring the reliability of automotive electronic systems. This standard not only strictly stipulates the testing requirements, but also promotes the quality improvement of the automotive electronics industry, and is an important cornerstone for ensuring the safety of automobile driving.

Certification and testing of automotive-grade standards

In the automotive industry, being a Tier 1 supplier in the supply chain is a role that is both honorable and challenging. To ensure that products can meet the stringent requirements of automakers, Tier 1 suppliers must meet two basic requirements: comply with AEC's AEC-Q series standards and pass IATF 16949 quality management system certification.

First of all, following AEC's AEC-Q series of standards is one of the key conditions for becoming a Tier 1 supplier. The AEC-Q series of standards, especially AEC-Q100, set clear standards for the performance and reliability of automotive electronic components. These standards not only require suppliers' products to withstand the test of extreme environments, but also emphasize strict control of the entire process of product design, production, and testing. Following the AEC-Q series of standards means that Tier 1 suppliers must continuously invest in technology research and development to improve product performance and reliability to meet the stringent requirements of the automotive industry.

Secondly, passing the quality management system certification of IATF 16949 standard is another basic requirement for becoming a first-tier supplier. IATF 16949 is a quality management system standard developed by the International Automotive Task Force (IATF) for the automotive industry. It requires companies to use process methods in the quality management system to continuously improve product quality, enhance customer satisfaction, and ensure compliance with technical specifications and legal and regulatory requirements of the automotive industry. Through IATF 16949 certification, first-tier suppliers can prove that they have a sound quality management system that can ensure the consistency and stability of product quality, thereby winning the trust and cooperation of automakers.

Automotive-grade standards play a key role in the field of automotive electronics. They not only ensure that automotive electronic components have excellent performance and withstand the test of extreme environments, but also ensure the stability and reliability of automotive systems through strict quality requirements. The formulation and implementation of these standards provide solid technical support for the automotive industry, enabling cars to operate safely and stably in various complex environments, providing passengers with a more comfortable and safe travel experience.
