Abstract: An application device for applying at least a solder resist onto both surfaces of a printed circuit board that are in particular provided with structurized printed conductors comprises at least two application bodies that can be assigned to the corresponding surface of the board and are rotatably supported. To simplify the structure of the application device while allowing a more rapid and well-reproducible application at both sides of a printed circuit board at the same time, the application bodies are two screen printing drums arranged at both sides of an essentially horizontal transport path of the printed circuit board, wherein a transport means comprises conveyor belts along the transport path for transporting the printed circuit board, and the transport means further comprises pressing means that can be pressed onto a surface of the board for holding the board on the conveyor belts.
