METHOD AND APPARATUS FOR APPLYING AND CURING A COATING ON A CIRCUIT BOARD

摘要

An automatic vertical dip coater provides for simultaneous ultraviolet curing of a conformal coating on both sides of a circuit board (18). A circuit board (18) to be coated on both sides with a conformal coating is placed on a tool (12) which is advanced towards a dip-coating tank (20) containing a ultraviolet radiation curable conformal coating (48) so that both sides of the circuit board (18) are immersed in said conformal coating to a predetermined position. The coating is then dried by means of opposed ultraviolet lamps (34,36).
