Abstract: 1410509 Printed circuits THOMSON-CSF 12 Oct 1972 [15 Oct 1971] 47204/72 Heading H1R A multilayer printed circuit structure (Fig. 1) comprises a polymer resin base 8 in which a conductor 1 overlies a layer 72 of insulant material spacing it from an embedded conductor 4 normal thereto, and underlies conductors 2, 3 at right angles thereto; the latter being spaced off from 1 by insulant block 71 and the former being spaced off from 1 by an interconnecting conductive eyelet 5 with bore 6 perpendicular to the conductors. In fabrication, a metallic sheet 21 of e.g. Cu, Sn-Pb, Zn or Ni is coated on each face with photosensitive resin 21, 22 in which aligned windows are formed by exposure, development and etch and a registering aperture in the metal is etched using, e.g. iron perchloride. Further exposure over a mask, development and etching produce openings 50, 51 of the resin defining the alignments of conductors 2, 3, and 52 on the other face defining the alignment of conductor 1 (Fig. 5). A second metal 2 of, e.g. Au, Ag, Cu is electrolytically deposited in the openings and in apertures 50, 51, 52, 40 (Fig. 6) and the residual resin is etched out; after which Cu, SnPb, Zn or Ni is electrolytically deposited at 80, and a resin coating 90 is deposited on the assembly (Fig. 9). An opening 100 is then formed to define the alignment of conductor 4 by mask exposure, development and etch, and the conductor is electrolytically deposited thereon (Fig. 11). After removal of residual resin, the assembly is bonded to a thermoplastic base, and further resin 130 is deposited on the upper face; in which an opening 131 is formed by mask exposure, development, and etch (Fig. 13). Further etching to attack Cu, SnPb, Zn or Ni without removing Au, Ag, Cu forms opening 140 penetrating between conductors 3, 4 and 1 to halve the width of conductors 3, 4; after which opening 140 is filled with photo-sensitive resin, which is exposed, developed, and removed leaving residues 150 (Fig. 15). The residual metal (Cu, SnPb, Zn or Ni) is etched out leaving the conductors 1, 2, 3, 4; resin residues 150, and base 8 (Fig. 16) after which resin is deposited on the assembly, mask exposed, developed, and removed to leave residues 170, 171 (Fig. 17).
