Patent ID: 8325459

Claim:
A circuit board comprising: a layer; a first via passing through the layer; a second via passing through the layer: a first set of electrical transmission line segments at a first area of the layer, wherein the first area is between the first and second vias and wherein at least one of the first set of electrical transmission line segments has a first thickness; and a second set of electrical transmission line segments on a second area of the layer, wherein the second area is offset to the first area and to the first and second vias, wherein, at least one of the second, set of electrical transmission line segments has a second thickness that is greater than the first thickness wherein the first set of electrical transmission line segment is connected to the second set of electrical transmission line segment to form an electrical transmission line, wherein an anti-pad area surrounds the first via, wherein circuitry is prohibited within the anti-pad area wherein the first and second thicknesses cause the electrical transmission line to have an average impedance that matches a line impedance of a uniform thickness line, and a connector line connected to the electrical transmission line, wherein the connector line has the line impedance of the uniform thickness line.
