ABSTRACT:
The composite part is constituted by a plate of flexible material such as plastic which has electrical and/or thermal insulating properties, at least one face of the plate being provided with a metal cladding which is subjected to a photoetching process in order to form raised metallic portions corresponding to a printed circuit pattern, for example. Permanent deformation of the raised metallic portions can be produced by means of a mechanical cold-forming process without exceeding the range of elastic deformation of the flexible plate.
