Zusammenfassung:	A flat flexible-printed-circuit cable is provided that is designed to route high speed digital bus signals across various printed circuit boards without substantial signal attenuation. The flat flexible-printed-circuit cable can include a polyimide substrate; a first layer of copper being a solid ground plane over the polyimide substrate; a dielectric continuous layer; a second layer of copper being a routing layer for high speed digital bus signals across various printed circuit boards; and connectors at ends of the cable having ground terminals to which the first layer contacts.
