Abstract

1,104,100. Flat cables; printed circuits. ROGERS CORPORATION. 16 March, 1963 [16 March, 1964], No. 11123/65. Headings H1A and H1R. A flat flexible multiple conductor cable is produced continuously by etching metal foil supported on an insulating resin film to form a plurality of parallel conductors and superimposing on the exposed conductors another insulating film. As shown in Fig. 1, copper foil 15 is kiss-coated on one side by contact with drum 17 which is partially submerged in resin solution in tank 10 and the coated foil heated in tower 19 to evaporate solvent and to cure the resin. Parallel strips of etch resist are deposited at 20 by e.g. silk screening or photoprinting and the unmasked metal removed in etching bath 20 containing, e.g. hot ferric chloride. The resist is removed by trichloroethylene in tank 13 and the foil, water-washed in tank 14, is passed through resin solution in tank 11, solvent is removed and the resin cured in heated tower 23. Alternatively, as illustrated by Fig. 3 (not shown), the foil is coated on both sides with resin solution and the cured resin stripped from one side which has been initially treated with a release agent. After etching, a preformed film, which may be that removed previously, is coated on one side with an adhesive such as a phenolic nitrile and contacted with the exposed conductor surfaces between heated pressure rolls. The flexible resinous material is preferably an aromatic polyimide, particularly a polyamide-imide as described in Specification 935,388, in which case the resin solution may be a polyamic acid precurser. Films of polyester, polyethylene, polyvinylidene fluoride, polyvinylidene chloride, PVC, polycarbonate, P.T.F.E. and P.C.T.F.E. may be used. Other suitable etchants are ammonium persulphate and nitric acid or, in the case of an aluminium foil, 50% H 2 SO 4 or concentrated HCl.
