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 makes it as well. Understand that they all have different properties and cures. The Emerson has an great secondary cure for shadowed areas.

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.
