Abstract
A multi-layered cable consisting of three or more conductive layers separated by layers of dielectric and/or adhesive material. The bottom layer and the top layer may act as return path for the transmitted signals and as a shield to prevent interference between these and external electrical signals. Located between the bottom layer and the top layer, the middle layer may transmit desired signals through the flexible cable. The material selection and specifics of each of the layers should be selected so as to achieve a balance in which the desired electrical impedance and mechanical flexibility requirements are met. The cable may also include one or more vias connecting the bottom layer to the top layer, providing shielding all the way around the flex cable. An additional conductive sock may be used to improve shielding effectiveness of the top and bottom layer and to connect to I/O connector shells and the system Faraday cage.
