ABSTRACT:
This invention relates to a process for making electrically conductive lines on a non-developable surface of an insulating substrate, to a tool for carrying out the process and to a device obtained thereby. The process consists in uniformly coating the surface of a layer of an electrically conductive matter, which is in turn coated with a layer of a protective matter. The contour of the lines is then traced mechanically on the layers by means of a tool hollowing out grooves, then the layers are subjected to the action of a chemical agent capable of attacking the layer of conductive matter without attacking the protective layer, after which those parts of the electrically conductive layer outside the lines are separated from the substrate by peeling. The invention is applicable, for example, to the making of electrically conductive lines on antenna reflectors.
