Abstract

A micro-coil prodn. process involves (a) winding a filament of non-conductive material about a wire of first metal so that the filament forms a spiral with interspaces; (b) connecting the filament-wound wire as cathode in an electroplating bath; (c) electroplating a second metal in the inter-spaces; (d) removing the filament; and (e) selectively dissolving the wire with an etchant which does not attack the second metal.
