Abstract
Process for manufacturing printed circuits, characterized in that it comprises the steps of evaporating a first layer of electrically resistive material on an electrically insulating substrate to form resistors, evaporating a second layer of material that is highly conductive of electricity in relation to the resistive material on the first layer of resistive material, and electroplating a third layer of conductive material on the second layer to form conductors comprising the second layer.
