Automotive Electronics
At a first glance, it appears that automobile electronics are being verified more strictly than general car-parts. But by further verification, the frequently used standards such as AEC-Q100, AEC-Q101, and AEC-Q200 set forth by the Automotive Electronics Council (AEC) are mostly based on test conditions of JEDEC and MIL-STD, added with separate new test methods, the conceptual structure of which is more complete than traditional ICs.

Automobile Electronics consist of three categories namely IC components, discrete semiconductors and passive components. For devices such as connectors, PCBs and mechanisms, the brand companies normally design in-house test specifications for suppliers’ reference. AEC recommends that car parts to be classified for the engine area and parts for the passenger area based on the intended location of use. The intrinsic heat resistance requirements of these parts are different, therefore different test temperatures are recommended. Due to variety of car part types, AEC recommends test conditions based on categorized part attributes. These recommendations significantly differ from most traditional specifications, and they cause less disputes.
Tests of automobile electronics are keen on lifespan concerns. More importantly, product structure and assembly quality are being considered in these tests, e.g., ;push and pull tests, solder joint strength tests, bending tests, etc., expanding the test scope from conventional electrical and environmental conditions (i.e. temperature and humidity) to stress and mechanism considerations. This is part of preliminary verification tests.

Another feature of test specifications is to suggest the consideration of EMC. The concept is that EMC of end products are mostly attributed to ICs, it is therefore necessary to conduct preliminary tests on ICs in the design stage, so as to eliminate potential risks of the finished goods. Furthermore, in the verification of automobile electronics, a rather particular point is to review sampling tests of both upstream and downstream production lines, differing from the design of regular parts where emphases are given to assemblies or product life tests.

It is extremely difficult for electronic parts to get in the supply chain of car parts, and the approval takes a long, long period of time. Taiwan, being the major operator of IC design, has taken only 3-5% market share of global automobile electronics. A great deal of room still exists for future expansions in automotive video entertainment ICs, discrete semiconductors and passive components.
