Abstract

1,131,165. Etching. STANDARD TELEPHONES & CABLES Ltd. 17 April, 1967, No. 17427/67. Heading B6J. [Also in Division B2] An etch-resist solution is applied by means of a stylus 32 to the upper surface of a substrate which has been previously coated with a layer of conductive material, e.g. platinum, gold or a platinum/gold alloy. After applying the etch resist solution to the discrete areas, the areas are exposed to a curing process, those areas not covered by the solution are then removed using a weak acid, and finally the etch-resist solution on the discrete areas is removed ultrasonically. The substrate may be quartz, glass or ceramic. The stylus 32 is fed with liquid from a reservoir 29 and is secured to a balanced head 5 which is pivoted about a supporting member and provided with electromagnetic lifting means 14 for moving the stylus into and out of contact with the substrate, the substrate support moving relative to the stylus in accordance with a predetermined pattern.
