Abstract
Provided is a printed circuit board having coplanar LC balance, comprising: an insulation layer, printed circuit patterns formed on the insulation layer, power source wirings supplying power in the printed circuit patterns, and at least three signal wirings formed between the power source wirings, wherein widths of signal wirings far from the power source wirings are wider than widths of signal wirings adjacent to the power source wirings to achieve LC balance, thereby reducing the skew between signal wirings and improving the quality of signal transfer.
