Hi We produce electronic pcboards for the aircraft industry. Some of our clients think that the thickness of the varnish left is proportional to the intensity of the blue color of uv's pigments in the varnish. Out off, we know that is not true. The

Contact the coating manufacturer to get their response. We use many different coatings every day and they all glow differently but that has no affect on the coating itself. As stated earlier, it's job is only as an inspection tool to identify where

We've had similar "disputes" with our quality department. A technical engineer from Nordson told me that the flourescents in the coating can look faint depending on the angle in which you look at the surface as well as how solder joints reflect the
