Question: What is the definition and purpose of AEC-Q100?


Answer: AEC-Q100 is a set of qualification test sequences for integrated circuits developed by the Automotive Electronics Council (AEC). AEC-Q100 establishes common part-qualification and quality-system standards for automotive electronics and is the industry-standard specification that outlines the recommended new product and major change qualification requirements and procedures for packaged integrated circuits embedded into automotive applications.
