Abstract

A method for producing thin film circuits in which a layer of oxidizable material is produced in a base of insulating material according to a scheme and the entire surface, or part of the surface, is anodically oxidized in an electrolyte, characterized therein because on a common basis there are arranged at least two thin-film circuits, which have to undergo electrolytic oxidation, and because additional connecting conductors have been arranged between the individual thin-film circuits so that all the parts of each circuit which they have to be oxidized they are electrically connected with contact points arranged at one edge of the base and because this base is then separated into two parts each of which contains a thin film circuit.
