CA 2402805

A rotation element (9,10), especially a contact cylinder is used to electrically contact printed circuit boards and conductor films in order to produce printed circuit boards and conductor films (7) wherein there is only a low amount of fluctuation in the layer thickness of the conductor structures without damaging the surfaces of said circuit boards and films, whereby an elastic, electrically conductive material (2, 5, 6) is at least partially applied to the bearing surface thereof rolling away from the printed circuit boards and conductor films.

Un élément de rotation (9, 10), notamment un cylindre de contact, est utilisé pour établir le contact électrique de cartes de circuits imprimés et de films conducteurs (7), afin de fabriquer des cartes de circuits imprimés et des films conducteurs à faible variation d'épaisseur de couche des structures conductrices sans endommager les surfaces desdites cartes et desdits films. L'invention est caractérisée en ce que, sur la bande de roulement dudit élément en contact avec les cartes de circuits imprimés et les films conducteurs, un matériau (2, 5, 6) conducteur élastique est appliqué au moins partiellement.
