Conformal coatings protect electronic circuits from harsh environments via a chemical film that “conforms” to a circuit board’s topography. These coatings protect against moisture, chemicals, contamination, vibration, corrosion, and thermal stress while improving product reliability by reducing failures. The benefits conformal coating can provide often vary in importance by industry. In aerospace electronics there is an emphasis on benefits of protection from corrosive gasses, outgassing, tin whiskers, and radiation. For the purpose of this article, we will focus on liquid coating materials.
