Automotive-Grade AEC-Q Certification
The AEC-Q series of certifications
is the recognized universal testing standard for automotive-grade components.
For IC design companies seeking to enter the automotive electronics sector,
and to join the automotive electronics component supply chain,
the AEC-Q series is one of the certifications that must be obtained.
Automotive electronics primarily rely on the Automotive Electronics Council (AEC) as the standard for automotive-grade validation, including AEC-Q100 (integrated circuits, ICs), AEC-Q101 (discrete components), AEC-Q102 (discrete optoelectronic devices, such as LEDs), AEC-Q103 (sensors), AEC-Q104 (multi-chip modules), and AEC-Q200 (passive components). The testing requirements for these standards are more stringent than those for consumer-grade chips.
I. The Necessary Path to Entering the Automotive Industry
Recognized Automotive-Grade Components
Universal Testing Standards
Chrysler, Ford, and General Motors established the Automotive Electronics Council (AEC) to create a set of universal standards for component qualification and quality systems. Although the AEC-Q series certification is not a mandatory certification system, it has now become the universally recognized testing standard for automotive-grade components and is the essential path to entering the automotive sector.
To enter the automotive sector and gain access to the supply chains of Tier 1 automotive electronics manufacturers, two “tickets” must be obtained. The first is the AEC-Q100 (integrated circuits, ICs), AEC-Q101 (discrete components), AEC-Q102 (discrete optoelectronic LEDs), AEC-Q103 (sensors), AEC-Q104 (multi-chip modules), and AEC-Q200 (passive components) reliability standards promoted by the North American automotive industry; the second is compliance with the ISO/IATF 16949 standard (Quality Management System) for supply chain quality management, which mandates “Zero Defect.”
II. Different Semiconductors Have Different AEC-Q Standards
Chip design companies must select the appropriate standard based on product classification, such as AEC-Q100 (IC chips), AEC-Q101 (discrete semiconductor devices), AEC-Q102 (optoelectronic devices), AEC-Q103 (sensors), AEC-Q104 (multi-chip modules), and AEC-Q200 (passive components).
To enter the automotive sector, companies must obtain the AEC-Q reliability standards from the Automotive Electronics Council, as well as the IATF 16949 specification for supply chain quality management, which mandates a “Zero Defect” policy.
III. AEC-Q Standards Are Stringent, and Certification Is Challenging
Automotive-grade electronic components are subject to strict requirements regarding environmental conditions, vibration and shock resistance, reliability, and consistency; therefore, more advanced technologies and more rigorous testing procedures must be employed.
Taking AEC-Q100 as an example, it specifies seven major test categories:
1) Test Group A (Accelerated Environmental Stress Testing)
2) Test Group B (Lifetime Simulation Testing)
3) Test Group C (Package Assembly Integration Testing)
4) Test Group D (Chip and Wafer Reliability Testing)
5) Test Group E (Electrical Characterization Testing)
6) Test Group F (Defect Screening and Monitoring Test)
7) Test Group G (Package Dents Integration Test)
AEC-Q100 certification is granted only after successfully passing all 41 tests across these seven major categories. On average, it takes approximately six months to complete all tests required for AEC-Q series certification.
IV. The Evolving AEC-Q Standards
AEC-Q100, AEC-Q101, and AEC-Q200 are the three most commonly cited AEC-Q standards.
The “Documents” page on the AEC website lists 37 standards and sub-standards, seven of which are marked as “New” or “Initial release.” Therefore, AEC-Q standards are constantly evolving. Particularly with the development of new technologies such as Advanced Driver Assistance Systems (ADAS) and autonomous driving, these standards will continue to be updated to meet the demands of new technologies and applications.
For example, standards specifically developed for optoelectronics, MEMS sensors, and multichip modules (MCMs):
-
AEC-Q102: Stress testing standards for optoelectronics in automotive applications
-
AEC-Q103: Stress Testing Standard for MEMS Pressure Sensors
AEC-Q104: Stress Testing Standard for Multichip Modules (MCMs) in Automotive Applications
