    摘要: A printed circuit board and a method of making same in which the board includes a common power plane having dielectric layers on opposing sides thereof and a signal layer on each of said dielectric layers, each signal layer comprising a plurality of substantially parallel signal lines running in substantially similar directions across said signal layers. Predetermined portions of the signal lines in one signal layer are aligned relative to and also parallel to corresponding signal lines in the other signal layer, with the power plane being located between these portions. Through hole connections are provided between selected signal lines in the two layers, these occurring through clearance holes in the power plane so as to be isolated therefrom.
