Abstract

A method of forming a flexible conductive strip includes: molding a continuous, flexible base of an electrically insulating thermoplastic resin, while forming channels in a surface of the base; at least partially filling the formed channels with a flowable, electrically conductive composition; and then stabilizing the flowable composition in the channels to form a pattern of stable, electrically conductive traces within the channels. A method of forming a flexible circuit board having loop-engageable touch fastener elements includes: molding a continuous, flexible base from an electrically insulating thermoplastic resin, while forming a field of stems integrally molded with and extending from a first side of the base; applying a conductive material to the base to form a pattern of electrically conductive traces in accordance with a circuit design; and forming loop-engageable heads on the stems.
