Abstract
Apparatus and process for curing conformal coatings on circuit boards being conveyed through a curing chamber within a UV oven. Warm air, exhausted from a lamp housing containing UV lamps for curing the coatings, is directed into a flash zone chamber through which the coated circuit boards are conveyed prior to entering the UV oven for flashing volatile constituents from the coatings and raising the temperature of the circuit boards.
