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

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.

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

Fusion makes UV ovens. Most conformal coating suppliers have a UV line. Great for quick cures, but the ovens interfered with our automated guided vehicles, so we had to abandon the UV.

Hi sforman1, The chemical that i'm using is a solvent based coating humiseal 1B73. From my understanding,the UV curing is mainly for UV curable coating like the UV40. And the main advantage of using UV curing is for fast throughput and environment

Hi, Option 3 is quite often used, while it is better to glue with uv glue using uv lamps for curing. For this process, two inverters are needed in the line, a dispenser for UV glue and a UV lamp (eg metronelec UV CURE OVEN). It is better to use prefo

Also be sure you know your material, as UV wave length will play a factor in your curing.

Shadow cure effects are dealt with by post cure mechanisims. New UV Coatings should have one, either heat or moisture cure. Basically UV primary cure starts off cure process, allows handling of the products. But UV is not suitable for all products
