Design engineers need both a basic understanding of why problems arise with excessive waste energy and greater knowledge about EMI mitigation techniques. Sometimes even an experienced staff can fail to spot an EMI issue early enough, potentially leading to production delays. All benefit from refreshing their knowledge about EMI suppression. In this basic overview, Laird outlines the issues and summarizes Laird™ brand solutions to countering stray EMI including surface mount shields, grounding contacts, gaskets, and form-in-place products.
