ABSTRACT:
In a flat flex cable, signal lines are surrounded by logic ground planes above and below which are viaed together left and right. The ground planes coupled with the flex cable dielectric determine characteristic the impedance and attenuation of the cable and provide differential signal EMI shielding. All signal layers and logic ground planes are enclosed within the two outermost shield layers which are viaed together left and right and around the connectors to enclose both signal layers and logic ground planes to provide common mode EMI shielding.
