A method of manufacturing a circuit board which may include the steps of forming a circuit board with horizontal and vertical fiberglass fibers, rotating the circuit board, and cutting the circuit board so that the horizontal and vertical fiberglass fibers form a non-right angle with a cut line of the circuit board. The circuit board may have a plurality of conductive traces located thereon which pass by areas of higher fiberglass-to-resin material and lower fiberglass-to-resin material to assist in reducing differential to common mode conversion between signals in the plurality of conducive traces.
