[Kristyna Zakova]
Electronic assemblies often face extreme conditions like humidity, temperature fluctuations, and corrosive gases that can affect their performance. Conformal coating offers essential protection, but contamination on the board before coating can reduce its lifespan and adhesion. To ensure effective and long-lasting protection, it's crucial to clean PCBAs before applying conformal coatings.

Electronic assemblies (PCBAs) are frequently exposed to extreme conditions such as humidity, temperature fluctuations and corrosive gases which can impair their functionality. Conformal coating provides required protection against such external influences. The purpose of conformal coating is to preserve the functionality of the assembly under such adverse conditions. However the presence of contamination on the board before coating application can shorten the expected life of assemblies and impair the adhesion of coatings. To ensure reliability of application and to ensure a long-term effectiveness of coatings, it is generally recommended to clean PCBAs before applying conformal coatings.
