Abstract
A printed circuit board apparatus, configurations and methods are presented which provide for close spacing between the HUB and multiple processors as well as a common configuration for two or four processor boards. A printed circuit board is provided with conductive apertures and portions corresponding to an efficient Packaging allowing for the attachment of the processor-chip on one side of the printed circuit board, and the HUB and other supporting electronic components on the other side of the printed circuit board. This configuration allows for the close spacing of the electrical conductors of the HUB and the processors without the limitations imposed by the physical dimensions of the respective hardware. Additionally, a symmetric packaging of the conductive apertures and portions about a centerline of the printed circuit board allows for a simple design modification to allow for a two two-processor board to be manufactured from a similarly configured four-processor board.
