Abstract
In a method of manufacturing foils of plastic material which are electrically conductive in a transverse direction, but not in the plane of the foil wherein micropassages are formed in the foil by etching nucleus traces which are generated by exposure to a heavy ion beam, conductive layers are deposited on one side of the foil and the micropassages are filled by electrolytic metal ion depositions from the other side until caps are formed on the passages. After dissolving the two conductive layers, the steps are repeated to form caps also on the passages at the other side of the foil so as to provide for good contacting capabilities at both sides of the foil.
