Abstract:
1. A printed circuit board, comprising: a substrate material; and a plurality of conductive features on a first side of the printed circuit board, said conductive features including a plurality of conductive pads arranged in an array of rows and columns configured to receive mounting thereon of an integrated circuit device, wherein at least one edge of a perimeter of said array is not fully populated with conductive pads, whereby spaces created in said at least one edge by missing conductive pads create additional routing channels for signals from conductive pads within said array to be routed external to said array through said at least one edge; wherein a first edge of said at least one edge includes a repeating pattern of a first conductive pad, a space, and a second conductive pad, positioned in series; and wherein a row or column of said array parallel and adjacent to said first edge is substantially fully populated with conductive pads.
