US 7,906,734 B2 · Electrical terminal footprints for a printed circuit board

Abstract

In one implementation, a PCB having an array of vias and electrical terminals disposed on the side of the PCB opposite the side configured to receive a grid array package are disclosed herein. The array of vias have pads and forms a pattern of repetitive rows and columns. A substantially consistent intervia distance is defined along an intervia axis between each adjacent via in each of the rows and columns. A pair of electrical terminals are positioned adjacent one another along an electrical terminal axis between at least two of the vias and the electrical terminal axis intersects the intervia axis. In another implementation, a group of four adjacent vias form a substantially rectangular shape having one of four vias positioned at each of four corners of the rectangular shape. One electrical terminal is positioned within the four vias without contacting any of the four vias.

Dependent claims

A printed circuit board (PCB), comprising:

an array of vias, wherein the array of vias forms a pattern of repetitive rows and columns of vias, wherein intervia distance between each of a plurality of pairs of adjacent vias is substantially constant along all columns and rows;
and
a pair of electrical terminals disposed on a first side of the PCB opposite a second side of the PCB configured to receive a grid array package, wherein the pair of electrical terminals are positioned adjacent one another along an electrical terminal axis between two of the adjacent vias, wherein the electrical terminal axis intersects the intervia axis between the pair of electrical terminals;
wherein each of the pair of electrical terminals are spaced apart from each of the intervia axes.
