Abstract
A method for the manufacture of screened or shielded interconnecting conductors (1) begins with semifinished foil products (H1, H2, H3), a first semifinished foil product (H1) having at least one layer of conductors (10, 10′, 12, 12′, 13, 13′) including signal conductors (10, 10′) and shielding conductors (12, 12′, 13, 13′). Another semifinished foil product (H2, H3) has shielding material (23, 33), which is joined by a dielectric (15, 25, 35) to at least one layer of conductors (10, 10′, 12, 12′, 13, 13′), in which the shielding material (23, 33) is provided by photochemical structuring near the shielding conductors (12, 12′, 13, 13′) with openings (22, 22′, 32, 32′) extending to the dielectric (15, 25, 35). The dielectric (15, 25, 35) is removed in accordance with the openings (22, 22, 32, 32) extending to the shielding conductors (12, 12′, 13, 13′) and by means of the openings (22, 22′, 32, 32′) the shielding material (22, 33) is electrically contacted with the shielding conductors (12, 12′, 13, 13′) so that signal conductors (10, 10′) are insulated by dielectr…
