Hi folks, I have a conformal coating application where I need the coating to be UV stable for a number of years without any crazing or cracking of the coating. I have looked for such a coating and have come up empty handed. Much of the circuit boar

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

I think it is useful just to see where varnish should not be (eg connection parts). it is necessary to use another method to measure the thickness.

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

I'm using urethane conformal coat and have fisheyes and dewetting after coating even though the PWAs have been through the wash cycle twice. I'm looking at using Ionox 13302 in an ultrasonic cleaner as a short term solution until root cause can be id

Tell them every action taken with the boards carries risk of damage. Process steps that don't do anything should be avoided because they carry the risk of causing defects. Even inspection causes the occasional defect, and board handling in general s
