Paper Abstract

This paper reports the progress attained in reducing electromagnetic interference (EMI) using UV-cured conformal coatings. A glass-epoxy PC board with two signal traces on one side and a ground plane on the other was used to measure the reduction in crosstalk. Measurements were made for several ordinary conformal coatings and several new EMI reducing coatings. The effectiveness of the EMI reducing coatings was also tested on commercial walkie-talkies.
