Patent ID: 7530167

Claim:
A method of making a printed circuit board, said method comprising: providing a substantially solid power plane having first and second opposing sides; positioning first and second dielectric layers on said first and second opposing sides of said substantially solid power plane, respectively; forming a first signal layer on said first dielectric layer substantially parallel to said substantially solid power plane and including a plurality of substantially parallel signal lines running in a single direction across said first signal layer from a first side of said printed circuit board to a second side of said printed circuit board; and forming a second signal layer on said second dielectric layer also substantially parallel to said substantially solid power plane and including a plurality of substantially parallel signal lines running in the same direction as said signal lines of said first signal layer across said second signal layer from said first side of said printed circuit board to said second side of said printed circuit board and of a substantially similar pattern as said signal lines of said first signal layer such that at least a predetermined large portion of the number of signal lines in said first signal layer are aligned with and substantially parallel to a corresponding large portion of said signal lines in said second signal layer and said power plane is located substantially between said predetermined portions of said aligned and substantially parallel signal lines in order to substantially reduce crosstalk between said first and second signal layers.
