Conformal coatings are designed to protect electronic components without significantly impacting their electrical performance. The coatings provide insulation against environmental factors but must maintain a high dielectric strength. While some coatings may introduce a minimal capacitance effect, proper selection and application ensure these effects remain within acceptable limits. Issues like coating thickness and uniformity are crucial to prevent interference. Overall, when applied correctly, conformal coatings maintain or even enhance electrical performance by shielding components from moisture, dust, and other contaminants, contributing to increased reliability and longevity in diverse operating conditions.
