Abstract:
1. A method for producing electrically conductive patterns on a non developable three dimensional surface of an electrically insulating substrate, which method starts by uniformly covering said non developable surface with a layer of an electrically conductive material, which is in turn covered with a layer of a protective material, after which the portions of said protective material layer which do not cover zones of said electrically conductive material layer intended to form said patterns are removed, then the portions of said electrically conductive material layer uncovered by removing said portions of said protective material layer are removed, wherein the removal of the portions of the protective material layer which do not cover said zones of said electrically conductive material layer intended to form said patterns is carried out by laser ablation with the aid of a mobile laser head which is moved, relative to said non developable surface covered with said electrically conductive material layer and with said protective material layer, in order to cover all the portions of said protective material layer which do not cover said zones of said electrically conductive material layer intended to form said electrically conductive patterns.
