Abstract

811,044. Etching. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Sept. 30, 1957 [Jan. 18, 1957], No. 1924/57. Drawings to Specification. Class 100(2) A method of manufacturing a predetermined design in metal foil on an insulating backing member from an insulating sheet having a layer of metal foil adherent to at least one face thereof includes the steps of covering the foil with a layer of etchant resistant paint, superimposing on the paint a layer, shaped to the required design, of a material insoluble in a predetermined solvent for the paint, applying said solvent to remove the paint except where protected by said insoluble material, and etching to remove the foil where the paint has been removed. The design and backing may constitute a printed electrical circuit or a name plate. The foil may be copper. The paint is a cellulose or alkyd based paint, applied by dipping. The insoluble material is shellac dissovled in alchol, applied through a silk screen after drying the paint. The solvent is polyethylene glycol, applied by dipping or spraying after drying the insoluble material. After etching the remaining paint and insoluble material is washed off.
