Hi Everyone, I have a few questions about conformal coating. Specifically acrylics. For reference, we apply the coating manually. What are the average coating thicknesses that you see after 1 coat? After 2 coats? Are you getting more than 0.001" of coverage in 1 or 2 coats? Given that soldermask is very lossy when it comes to SI, I would assume the coating has similar properties (still waiting for vendor data). Have you had any odd failures (from an RF stand point) with a 0.001" coating thickness versus say 0.002" or 0.003"? The data sheet specs a Dk and Df @ 1 MHz, but I am extremely interested in these at RF frequencies. Has anyone done any studies about this that can share the findings?
