Despite conformal coatings’ ability to dependably protect substrate surfaces of printed circuit boards (PCBs) and related electrical components, problems can sometimes occur which compel their removal. Chemical removal, which does the least damage to PCBs, is fine for wet coating substances like acrylic, epoxy, silicon and urethane. Chemical removal methods are far less successful for [&he
Due to its excellent ability to stop the passage of gases, liquids, or radiation onto circuit board components, parylene is often considered to be the ultimate conformal coating for the protection of devices, components, and surfaces in many industries.

Understanding the characteristics of various conformal coating types, and their interactions with the extreme range of products and materials to which they are applied, ensures optimal function, performance reliability and product-life. Designers and users of conformal coatings should be aware of the properties of various types of conformal coatings and their interactions with the parts/materi
