For more than 50 years, the automotive industry has experienced pressures from increasing consumer demand for better safety, reliability and performance in vehicles. While a glance under the hood presents all the familiar mechanical workings of an automobile, today’s vehicles actually have over 60 electronic components to keep things running smoothly, while offering consumers the comfort and convenience they’ve come to expect. Several of these processors and components require varying degrees of timing accuracy, which results in the need for multiple different timing solutions. This is where ECS Inc.’s AEC-Q200 qualified crystals come in.

The AEC-Q200: A Brief History

As the electronic industry began its surge in the 1990s, automotive manufacturers continued to be bumped lower on the priority list for electronic component manufacturers. This decline meant that it became more difficult for companies to manufacture components that adhered to the strict requirements necessary for the manufacturing of automobiles.

The idea of a standard was eventually proposed, and thus birthed the Automotive Electronics Council, or AEC. This council was composed of automotive tycoons of the day, along with experts in multiple passive component manufacturing companies, and ultimately crafted the standards that are still used to this day.

Changing the Face of Automotive Fabrication with AEC-Q200 Qualifications

The purpose of the AEC-Q200 is to standardize specific levels of performance in passive electronic components used in a vehicle. This includes temperature and pressure resistance, as well as consistency and safety. The testing and qualification process a component must go through to be deemed AEC-Q200 qualified is one of the most rigorous in the industry. The AEC-Q200 qualification process includes a significant number of stringent testing procedures, including:

  • An initial round of electrical testing, followed by layering on stress and an additional round of electrical testing to determine component integrity
  • Exposure of the part to the maximum temperature within that product’s range for a prolonged period of time to test the part’s temperature resistance; this is followed by temperature cycling through the entire range, plus an additional round of measurement
  • Testing the component’s moisture resistance by exposing it to a significant degree of humidity for a prolonged period
  • Checking the operational life of the component
  • Testing the component’s resistance to solvents
  • Exposing the component to high levels of g-force for prolonged periods of time to test mechanical shock and vibration resistance; parts are also cycled through periods of vibration
  • Testing the solderability of the component, as well as their resistance to soldering heat
  • Verifying the board flex and terminal strength of the component to ensure compliance
  • Strict visual inspection and a final check of physical characteristics
