UV curable conformal coatings: meeting the demands of the electronics industry

UV (ultraviolet) curable conformal coatings that provide superior moisture protection, good electrical insulating properties, and excellent adhesion to a variety of surface board substrates have been developed. The quick cure cycle of the UV coatings allows for inline processing and reduces the manufacturing cycle time. The author presents an overview of the performance properties and the processing advantages that UV curable conformal coatings provide to meet the demands of the electronics industry today. It is concluded that the use of UV curable material allows for a decreased production cycle with improved reliability and consistency of the finished products. Thus, a system using UV curable materials can be a cost-effective way to improve processing and reliability in printed circuit assembly
