For manufacturing printed circuit boards and films 7 with little variations in the layer thickness of the circuit structures without damaging the surfaces of the boards and films, a rotatory element 9, 10, more specifically a contact roll, is used for placing the printed circuit boards and films in electric contact, an elastic, electrically conductive material 2, 5, 6 being at least partially applied on the running tread unreeling on the printed circuit boards and films.
