A method and apparatus for reducing timing skew between conductor traces. A dielectric medium made of a resin reinforced with a fabric is provided. The fabric includes a first plurality of yarns running parallel to a first axis and a second plurality of yarns running parallel to a second axis. The first plurality of yarns are separated by a first weave pitch and the second plurality of yarns separated by a second weave pitch. At least two conductor traces are formed on the dielectric medium. The conductor traces are positioned on the dielectric medium such that the conductor traces each have substantially similar effective dielectric constants.
