What is AEC-Q Certification Testing?

The Automotive Electronics Council (AEC), initiated by Chrysler, Ford, and GM in 1994, has grown to include members from major automotive and semiconductor companies worldwide.

AEC-Q is a reliability testing standard for automotive electronic components established by the AEC. Meeting AEC-Q certification testing requirements is crucial for enhancing product competitiveness and swiftly entering supply chains, making it a threshold for entry into the automotive sector.

AEC-Q Certification Standards

The AEC-Q product standards have strict control requirements. Only by passing all the test items specified by the corresponding product standards can a product be claimed to have met the respective AEC-Q product standard requirements.

Although AEC-Q is not a mandatory product standard, it has become a widely recognized general standard for automotive-grade components.

- AEC-Q100: Applicable to various integrated circuit chips.

- AEC-Q101: Applicable to discrete devices such as BJTs, FETs, IGBTs, diodes, varactors, Zener diodes, etc.

- AEC-Q102: Applicable to optoelectronic devices such as LEDs, lasers, photodiodes, and phototransistors.

- AEC-Q103: Applicable to MEMS devices like pressure sensors and microphones.

- AEC-Q104: Applicable to various multi-chip modules (MCM).

- AEC-Q200: Applicable to components such as tantalum and ceramic capacitors, aluminum electrolytic capacitors, resistors, inductive devices (inductors/transformers), networks (R-C/C/R), film capacitors, thermistors, adjustable capacitors/resistors, varistors, polymer PTC resettable fuses, quartz crystals, ceramic resonators, ferrite EMI suppressors/filters, etc.

Testing Items

- Parameter Testing: Functional verification, electrical performance parameters, optical parameters, thermal resistance, physical dimensions, avalanche endurance, short circuit reliability, etc.

- Environmental Stress Tests: High-temperature operation, high-temperature reverse bias, high-temperature gate bias, temperature cycling, high-temperature storage, low-temperature storage, high-pressure cooking, HAST, high-temperature high-humidity reverse bias, high-temperature high-humidity operation, low-temperature operation, pulse operation, intermittent operation life, power temperature cycling, constant acceleration, vibration, shock, drop, gross/fine leak testing, hermeticity, salt spray, condensation, hydrogen sulfide gas corrosion, mixed gas corrosion, etc.

- Process Quality Evaluation: DPA, terminal strength, solvent resistance test, solder heat resistance, solderability, shear force, lead-free testing, flammability, flame retardancy, board bending, shooting speed load, etc.

- ESD: HBM, CDM, LU.

Current Status and Issues with Automotive Grade Component Testing

- Reports not fully compliant with AEC-Q standards, incomplete testing items, or reports lacking specific testing items.

- Incomplete evaluation or incorrect selection of product standards when dealing with new products involving AEC-Q103 and AEC-Q104.

- Confusion in family categorization and misuse of general data in AEC-Q101/AEC-Q102 and AEC-Q200 due to the wide range of applicable product series.

- With the advancement of automotive electrification and intelligence in China, many new highly integrated products have emerged, but existing AEC-Q standards cannot cover all products comprehensively.

- Consistency in batch product quality cannot be maintained by manufacturers despite AEC-Q test sample qualification. The JJR Laboratory in China offers testing services, potentially saving you 30% on testing costs; request a quote.
