Abstract: 1,030,925. Printed circuits. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. April 3, 1963 [April 10, 1962], No. 13194/63. Heading H1R. [Also in Division H2] A printed circuit is made by shaping at least one conductive layer on a mould surface to form a pattern having peaks or ridges, uniting such layer(s) on the mould with an insulating base, and removing the peaks or ridges to produce the desired circuit pattern. In one embodiment, a conductive sheet 1 is placed between a mould 2 and a hard rubber plate, and pressure is applied to produce peaks 6, Fig. 3a, in the sheet 1 without substantially reducing the thickness thereof. A sheet thus shaped is placed on either side of a base 8 of fibres impregnated with uncured resin and heat and pressure are applied simultaneously to embed the plane portions of the sheets in the base and to cure the resin. The moulds are then removed and the peaks 6 removed by abrasion or pumicing to produce a two-sided printed circuit. Unwanted plane areas of the conductive plates may be removed by an etching process, which may also be applied to peaks 6 as an alternative to abrading. Where large areas of the conductive plates are to be removed, a mould 2 having large recesses may be used, the unwanted material being deformed into the large recesses and subsequently removed. In another embodiment (Fig. 8, not shown), conductive layers 21, 31 are electrolytically deposited on profiled stainless steel plates 22, 32 having surface layers 23, 34 of or containing chromium, and are then united to a base 28 and subsequently treated as described above. In an alternative method of uniting the conductive plates with the base, the latter is rigid and the plates are bonded thereto by adhesive. The printed circuits may be plated with nickel or nickel alloy. Circuits on either side of the base may be interconnected by soldering or welding together tabs extending beyond the periphery of the base, by electrolytic metallization of holes in the base following electroless sensitization thereof, or by distorting conductors on either side of the base into an enlarged hole in the base to form portions which make contact and may be soldered or brazed together; such portions may be formed during the moulding operation. Interconnection by riveting and edge groove metallization is also mentioned. The windings of rotor and/or stator members of electrical rotating machines of the annular air-gap type may be made according to the invention.
