A layout of a printed circuit board adaptive to be bonded to an integrated circuit device is introduced here. The layout includes a first metal layer, disposed in a first insulation layer and a second metal layer, disposed in a second insulation layer over the first insulation layer. The first metal layer and the second metal layer are connected to each other through a plurality of contact hole filled with conductive materials and are arranged to be substantially parallel to each other throughout a pad structure region and a line structure region of the printed circuit. The connected first metal layer and second metal layer are used for a signal path from the printed circuit board to the bonded integrated circuit device to improve driving ability of power supply.
