Ethernet solutions have been popular in industrial and computing applications for several decades but were not widely adopted in the automotive area. Automotive ethernet enables fast and robust data communication, with high flexibility in bus topologies for multiple electronic control units (ECUs).

Tin whiskers are small, hair-like structures that can form naturally from the surface of tin components. This article explores potential contributors to tin whisker growth, failure mechanisms that may be induced by whiskers, current testing standards and processes, and mitigation strategies, with a particular focus on the automotive industry.

Speed and determinism in design, made possible by time-sensitive networking (TSN) technology, is prompting the development of new TSN profiles for a multitude of applications across industry sectors. The IEEE 802.1™ Working Group of the IEEE Standards Association (IEEE SA) offers numerous TSN profiles for applications, including the automotive, manufacturing, and aviation industries.

The history and insight into how the EMC specifications and procedures evolved at one automotive original equipment manufacturer (OEM). Other present-day OEM specifications are more similar than different mostly due to the extensive reference to international standards which these OEMs have taken part in developing (e.g., EMC committees). Knowing this history should help today’s EMC practitioners, especially those new to the discipline, gain some insight into the implementation and limitations of test procedures and when to be flexible in analyzing test results.

EV batteries and battery packs are complex systems, requiring a comprehensive design and testing strategy to help ensure safe and efficient electrical power.

As they become more commonplace in today’s motor vehicles, advanced driver assist systems (ADAS) require a unique set of testing procedures that include repeatability of the trigger mechanism in a safe, controlled environment to accurately measure their effectiveness.

The U.S. Federal Communications Commission (FCC) has redesignated a portion of the 5.9 GHz...

This article presents the importance of defining product case and load simulator grounding in an automotive EMC test plan.
