ABSTRACT:
The present invention relates to a printed circuit board. In one embodiment, a printed circuit board includes a dielectric layer and a conductive trace formed on the dielectric layer. The conductive layer includes a first conductive portion, a connecting portion and a second conductive portion. The connecting portion includes a first end and a second end. The first end is connected to the first conductive portion; the second end is connected to the second conductive portion. A width of the connecting portion gradually decreases from the first end to the second end. Reflection and cross talk of signals transmitted in the presented printed circuit board can be reduced.
