Some UV cure coatings do not have the correct rheology for sticking to small sharp corners. 984 is one of them. MicroCoat Technologies, Allen, TX makes one that works every time.

I use conformal coating DYMAX #984-LVUF and I don't know if it's a problem of viscosity but 0805 components are not covered properly. We use a dispensor to applied it and we cured it by UV. Even if I apply a thicker layer, the coating seems to have

Normally, some conformal coatings do not have very good wetting properties, that should be basic function of a good coating material (the same reqirement as avoid bubbles during coating process)! For UV curing conformal coatings, you can try Lackwe

Hopefully the coating does contain a UV tracer. We used a silicone years ago that did not, but UV did make it fluoresce to a degree, you just couldn't ensure 100% coverage. One time we did have a problem with the coating getting on connector pins,

We use a Luxo handheld magnifier that has both UV and white light built in. You can get one from Techni-Tool (p/n 516IN401) or HMC Electronics (p/n 16401).

You can buy bulbs for any T8 T10 fixure. You can buy black light bulbs or white uv bulbs and just pop them in. There should be a bulb supplier in your city that has them.

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.

Does anybody run conformal coating process using UV cure varnish? We have a long experience on solvented urethane coating material but switching to solventless is unknown for us. Could you recommand vendors for UV curing oven? Thanks

We use one quite often. Our machine is a Uvitron Conveyor 40 as we are a large coating house and this allows us to process many boards. Dymax also maufactures and sells machines as well. Humiseal and Dymax both manufacture UV coatings. Emerson Cuming
