Patent ID: 7399705

Claim:
A method for producing at least one local coating on a substrate, comprising: arranging a removable mask on the substrate, the mask being removable in a non-destructive manner, and the mask having at least one perforation; at least partially filling the perforation with a reactive solution; and inducing a coating reaction of the reactive solution with a surface of the substrate to form the local coating; wherein: the substrate is provided with a first electrically conductive layer and a second electrically conductive layer; an electrode, embodied as a moveable contact pin, electrically contacts the first and second electrically conductive layers one after another to induce the coating reaction; a galvanic voltage is applied to the electrode; and the galvanic voltage is applied between at least one of: i) the electrically conductive layers and the substrate, and ii) the electrically conductive layers and an additional electrode.
