The invention relates to a method for producing electric trigger elements for pyrotechnic articles such as fuses or igniters, wherein, in a first stage, a) a lacquer is applied by photolithography to an electrically non-conductive substrate, b) a conductive material having a specific resistance of 0.1 Ω*mm to 5.0 Ω*mm is applied to the lacquer and substrate by means of a PVD process in a layer thickness of 0.02 μm to 8.0 μm, and c) the lacquer is removed from the substrate, and possibly, in a second stage, d) a photolithographic process is again carried out in which a precisely defined region of the resistor strip is covered with photoresist, e) the entire substrate surface is covered with a layer of a metal having a specific resistance of 0.01 Ω*mm to 0.1 Ω*mm in a thickness of 0.1 μm to 20 μm, wherein the application of the metal is configured such that in regions which have a bare substrate from the first photolithographic process, no metal adheres, and f) the lacquer from the second photolithographic process is again removed. |
