Abstract
A method of applying discrete areas of a noble metal to individual pads on a flexible printed circuit board comprises the steps of forming a particular pattern of electrically conductive material on a flexible, electrically insulating substrate. The pattern includes individual pads. An aperture is formed through the electrically insulating substrate to expose a portion of the underside of at least one of the individual pads, and then contacting the underside with an electrode, contacting the upper surface of the individual pad with a wire comprised of the noble metal, applying a welding current between the electrode and the wire to weld the wire to the pad and severing the wire to leave a particular amount on the upper surface of the pad.
