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. The first vapour-removal and drying station is so arranged between the first and the second coating stations that its longitudinal extent is transverse to the transport directions of the printed circuit boards in the coating stations. Holding devices for the printed circuit boards, which devices are secured to the ascending section of a circulating conveyor, preferably a chain conveyor, extend transversely to the first apparatus line while holding devices that are secured to the descending section of the circulating conveyor extend transversely to the second apparatus line.
