Abstract
A ribbon cable with improved skew control has a plurality of substantially parallel longitudinal conductors lying in a single plane, with insulation encasing the plurality of conductors. The insulation defines first and second outer surfaces which are substantially parallel to the plane of the plurality of conductors. A first sheet of extensible metallic foil is positioned adjacent the first outer surface of the insulation, and a second sheet of extensible metallic foil is positioned adjacent the second outer surface of the insulation. A third sheet of metallic foil is wrapped around substantially all cross-sectional sides of the plurality of conductors, insulation, and first and second sheets of metallic foil to provide a continuous electromagnetic shield around the conductors. A flexible jacket may be provided on the cable to protect the assembly.
