AEC (Automotive Electronics Council)
The body, originally formed by US automakers and their suppliers, that publishes the Q-series qualification and part approval specifications for automotive electronic components.
It is a component qualification standards group rather than a broad trade association.

Notes
Established in the early 1990s by Chrysler, Ford and General Motors to create a common component qualification baseline.
Overview
The AEC (Automotive Electronics Council) is the automotive industry body that publishes the Q-series stress test qualification documents for electronic components, notably AEC-Q100 for integrated circuits, AEC-Q101 for discrete semiconductors and AEC-Q200 for passive components. It was set up in the 1990s by Chrysler, Ford and General Motors to create common part-qualification and quality-system standards. It works as a component standards group rather than a broad trade association.
How it works
The AEC's Component Technical Committee writes and maintains the documents. Each qualification specification is built around failure-mechanism-based stress tests, covering factors such as temperature, humidity, voltage variation and ESD susceptibility, and the requirements are graded by the temperature range a part must survive; Semiconductor Engineering cites minus 40 to 150 degrees Celsius as an example. The intent is that a component meeting the specification can be used in the harsh automotive environment without further component-level qualification by each customer.
The main documents are backed by detailed test methods. The ESD Association reported, for example, that an AEC sub-team was updating the charged device model methods in AEC-Q100 and AEC-Q101 to incorporate the joint JEDEC and ESDA JS-002 standard, with AEC-specific test conditions. The documents are distributed from the council's own website.
Qualification is a baseline rather than the whole story. Automotive customers keep pushing defect rates down, from a long-standing target of around 10 defective parts per million towards 10 per billion, which drives extra screening such as outlier detection and inline defect inspection. The AEC's reliability workshops are one forum where component makers and carmakers share such methods.
Examples
- A microcontroller maker qualifying a new automotive part to AEC-Q100 before releasing it to tier-one suppliers.
- A component maker certifying its plants to AEC-Q100, Q101 and Q200 alongside aerospace and medical standards.
- Aligning the AEC charged device model test methods with the joint JS-002 standard.
- Engineers presenting inline defect screening results for automotive chips at an AEC reliability workshop.
Why it matters
Chips sold into cars are generally expected to be qualified to the relevant AEC document, so the council's specifications shape qualification plans, test flows and datasheets for automotive suppliers. Automotive qualification engineers, reliability engineers, customer quality engineers and quality programme managers work with them most.
