Category Archives: Conformal Coating
The pervasiveness of electronics in every manufacturing industry has provided unique challenges. Manufacturers are tasked with protecting these components
in environments that make
electronics vulnerable to even minute amounts of moisture, debris and environmental contamination.
A useful solution to this problem is conformal coating. Conformal coating is a thin (usually 25-75µm thick) chemical or polymer film (parylene and acrylic are popularly used, depending on the application) that covers an electronic component to act as a barrier against contamination and a defense against moisture. While, this capability massively enhances the protection of, and therefore the reliability of, electronics, manufacturers have been overlooking a key element to dependability in this system: surface condition.
Here are four major factors that could lead to poor adhesion which manufacturers are often unaware of the impact they have:
