1. AEC-Q100 – Failure Mechanism Based Stress Test Qualification for Integrated Circuits, formulated by the AEC. It serves as a comprehensive reliability test and certification standard for automotive IC chips and the basic threshold for chips to be applied in automotive scenarios.

First released in 1995, the standard has been continuously updated up to Revision H issued in 2014, which remains the currently applicable version. AEC-Q100 specifies mandatory test items that chip products must complete and pass in accordance with requirements on product types, package forms and sample quantities.

2. AEC-Q101 – Failure Mechanism Based Stress Test Qualification for Discrete Semiconductors, formulated by the AEC. It is a comprehensive reliability test and certification standard for automotive discrete semiconductor devices and the basic entry requirement for discrete semiconductors used in automobiles.

First published in 1996, the standard has been updated to Revision E released in 2021, the latest version in use today. AEC-Q101 defines essential test items that discrete semiconductors must conduct and pass subject to rules for product categories, package styles and sampling volumes.

3. AEC-Q102 – The Automotive Electronics Council (AEC) officially released AEC-Q102 Rev standard in March 2017. This specification establishes evaluation criteria for discrete optoelectronic components entering the automotive market and is currently the universal international standard for automotive LEDs.

Its verification items include redefined sample quantities, revised LED Tj (Junction Temperature) control methods, and newly added gas corrosion testing. All items are designed targeting various environments that automotive LEDs may encounter to guarantee driving safety.

LED light sources are widely adopted in automobiles for applications such as vehicle lighting, LiDAR, intelligent systems and blind-spot detection, driving numerous LED component suppliers to expand into the automotive LED sector. Passing AEC-Q102 verification is one of the most critical credentials for LED manufacturers to gain market share in automotive electronics.

4. AEC-Q103 – A testing standard developed by the Automotive Electronics Council (AEC) tailored to the characteristics of vehicle-mounted MEMS. Previously, automotive qualification for MEMS micro-electro-mechanical systems was conducted with reference to AEC-Q100. This dedicated standard delivers more targeted industry requirements and enables more reasonable automotive-grade certification for MEMS components. AEC-Q103 lays out mandatory test items that vehicle MEMS devices must fulfill and pass based on product types, package forms and sampling rules, and zero failures are required to obtain qualification approval.

5. AEC-Q104 – The specification is divided into eight series from A to H. One core rule states that if all components integrated into an MCM (including passive components such as resistors, capacitors and inductors, discrete diodes and IC chips) have previously passed AEC-Q100, AEC-Q101 or AEC-Q200, the MCM product only needs to complete 7 tests specified in AEC-Q104H: 4 reliability tests including TCT (Temperature Cycle Test), Drop Test, Low Temperature Storage Life (LTSL), Start Up & Temperature Steps (STEP); plus 3 destructive and non-destructive inspection tests: X-Ray, Acoustic Microscopy (AM) and Destructive Physical Analysis (DPA). If the components on the MCM have not obtained prior qualification under AEC-Q100, AEC-Q101 or AEC-Q200, manufacturers shall select applicable verification items from the full set of 49 tests covering Series A to H of AEC-Q104 based on product applications, resulting in a much larger scope of testing.

6. AEC-Q200 – On March 20, 2023, the AEC issued the latest test and qualification standard for passive components: AEC-Q200 Rev E: STRESS TEST QUALIFICATION FOR PASSIVE COMPONENTS.

Two major revisions are introduced in the new standard:

1. The scope of applicable products is expanded from the original 14 categories to 16, adding niobium capacitors, fuses, supercapacitors, trimmer resistors and other product types.

2. The number of test samples is redefined according to product volume, split into three tiers: <10cm³, 10cm³ ≤ x ≤ 330cm³, and ＞330cm³. Larger devices require fewer test samples. Taking temperature cycle testing as an example, products with volume <10cm³ require 77 samples, those between 10cm³ and 330cm³ require 26 samples, and units larger than 330cm³ only need 10 samples.
