    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.

    Abstract: An exemplary method for manufacturing a printed circuit board is provided. In the method, firstly, a circuit substrate having a substrate and a number of soldering pads is provided. Secondly, a protective layer is formed onto the circuit substrate in a manner such that the soldering pads are entirely covered by the protective layer. Fourthly, a laser beam is applied onto portions of the protective layer spatially corresponding to the soldering pads in a manner such that the portions of the protective layer is removed, thereby exposing the soldering pads to an exterior. A printed circuit board having a protective layer with high precision of resolution is also provided.
