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.
Claims19
A printed circuit board having coplanar LC balance, comprising:
- an insulation layer;
- printed circuit patterns disposed on the insulation layer;
- power source wirings supplying power in the printed circuit patterns;
- at least three signal wirings disposed on the same plane as and between the power source wirings,
- wherein widths of the signal wirings farther from the power source wirings are larger than widths of the signal wirings closer to the power source wirings to achieve LC balance.
A printed circuit board having LC balance, comprising:
- an insulation layer;
- printed circuit patterns disposed on the insulation layer;
- power source wirings supplying power in the printed circuit patterns;
- at least three signal wirings disposed on the same plane as and between the power source wirings in the printed circuit patterns;
- and
- a plurality of external connection terminal lands connected to the power source wirings and signal wirings in the printed circuit patterns,
- wherein an additional tail wiring is disposed on one end of the external connection terminal land that is connected to a shorter wiring of the at least three signal wirings, and
- wherein widths of signal wirings far from the power source wirings are greater than widths of signal wirings adjacent to the power source wirings.
