RM 105: Conformal Coating Material Selection Best Practices

Today we’re diving into conformal coating best practices. With the explosion of IoT, the electrification of vehicles, and the miniaturization of circuit assemblies and associated components, many of which are operating in harsh environments, the need for conformal coating has never been greater. Coating your assemblies? Where does one start? What material should one choose? Should it be applied in-house or through a contract-coating house? What are the best practices in materials selection, application, inspection, and thickness? So many questions! To answer these and other questions, Mike Konrad invited a conformal coating expert to shed light on this subject. David Greenman began his career in the conformal coating business at Concoat distributing Humiseal products and eventually manufacturing them under license for Europe, the Middle East, India and Africa. After 25 years of distributing and manufacturing Humiseal products, Chase Corp, which owns Humiseal purchased Concoat. David now serves as director of Humiseal UK, Europe and India, responsible for corporate responsibility as well as supporting HumiSeal sales and technical teams. He is qualified as a radio, TV/electronics engineer and a member of The Society of Radio and Electronics Technicians, now the Institution of Engineering and Technology.
