Abstract
A printed circuit board includes signal layers, ground layers, and a power layer, which are superposed. A closed trace is set along edges of each of the signal layers and the power layers. A number of vias are defined in each trace at intervals. Each via extends through the signal layers, the ground layers, and the power layer. Each via is electrically connected to the traces of the signal layers and the power layer, and electrically connected to the ground layers.
