A semiconductor device has a semiconductor die with a die pad layout. Signal pads in the die pad layout are located primarily near a perimeter of the semiconductor die, and power pads and ground pads are located primarily inboard from the signal pads. The signal pads are arranged in a peripheral row or in a peripheral array generally parallel to an edge of the semiconductor die. Bumps are formed over the signal pads, power pads, and ground pads. The bumps can have a fusible portion and non-fusible portion. Conductive traces with interconnect sites are formed over a substrate. The bumps are wider than the interconnect sites.
