1. A printed circuit board, comprising:a central dielectric layer including at least one fiber that provides mechanical strength for the printed circuit board;
a top dielectric layer disposed above the central dielectric layer;
a top electrical trace layer positioned between the central dielectric layer and the top dielectric layer, top electrical trace layer being patterned to form a top electrical trace having longitudinal ends that electrically connect through the top dielectric layer by electrically conductive vias; and
a bottom electrical trace layer positioned below the central dielectric layer, the bottom electrical trace layer being patterned to form a bottom electrical trace having longitudinal ends that each electrically connect through the central and top dielectric layers by electrically conductive vias, at least a portion of the bottom electrical trace being parallel to and directly below at least a portion of the top electrical trace.
