The present invention relates to a process for the fabrication for multilayer articles having electrical connections between conductor patterns on at least two layers, of the multilayer article. The process comprises at least the steps of: a) using an initial set of image data describing a first article or layer having a conductor pattern thereon, forming the first article or layer having a pattern of conductive material thereon; b) taking data of an image of the pattern of conductive material on the first article or layer; c) determining from the image of the pattern of conductive material on said first article or layer that are to be connected to sites on a pattern of conductive material on at least a second layer having conductor patterns thereon; and thereafter performing steps selected from the group consisting. |
