Optimizing Conformal Coating Coverage for Improved Environmental Corrosion Protection - Free Webinar

Conformal coating is widely used to provide environmental protection for electronics in challenging environments with high relative humidity, corrosive gas and dust concentration as well as in coastal environments. Although the physical and chemical properties of conformal coatings are often characterized and studied, very little research has been done to understand the effectiveness of conformal coating in protecting electronics in various harsh environments. This work examines the effect of conformal coating coverage, especially the coating thickness, on the environmental protection of the conformal coating. Results of optimizing coating coverage and quality control will also be presented.
