ABSTRACT:
A method of forming conductive end portions on a flexible circuit member having a dielectric layer (e.g., polyimide) with at least one conductive element (e.g., copper) thereon. The method comprises the steps of forming (e.g., punching) an opening through both dielectric and conductive element, providing (e.g., additive plating) an electrically conducting layer on the opening's internal surface, providing (e.g., electroplating) a plurality of dendritic elements on the conducting layer's surface, and thereafter removing (e.g., punching) a portion of the dielectric and conductive element such that the formed dendritic elements (e.g., palladium) project from the flexible circuit's conductive ends.
