Abstract: A method and an apparatus for coating printed circuit boards on both sides are described in which the printed circuit boards are transported through several consecutive processing stations of a coating installation. In a first coating station, one side of the printed circuit boards is wet-coated with preferably UV-hardenable plastics and the printed circuit boards are subjected to vapour-removal and drying in a first vapour-removal and drying station. The printed circuit boards are turned and, in a second coating station, their second side is wet-coated with preferably UV-hardenable plastics and then are subjected to vapour-removal and drying in a second vapour-removal and drying station. The boards are finally transferred from the coating installation to other processing apparatuses for further processing. In the coating operation, the printed circuit boards are transported in opposite directions through the two coating stations which are arranged side by side in two parallel lines of apparatus.
