ABSTRACT:
A method, system, and apparatus for optimizing routing layers and board space requirements for a ball grid array package is described. The ball grid array package includes a substrate material having a first side configured to receive a semiconductor chip and a second side having a plurality of conductive pads arranged in an array of rows and columns. The array of pads has at least one edge not fully populated with pads.
