Patent ID: 7602615

Claim:
An electronic circuit board (ECB) comprising: a ball grid array (BGA) of BGA pads on one side of the ECB, arranged in a grid pattern of rows and columns; through hole vias extending from said one side of the ECB to an opposite side of the ECB, and wherein at least one contiguous pair of said through hole vias are filled with a conductor, and wherein each of said though hole vias of said contiguous pair is offset from a corresponding one of said BGA pads and connected to said corresponding BGA pad by a conductor on said one side; a contiguous pair of octagonal conductive pads on the opposite side of the ECB, each pad of said pair of octagonal conductive pads arranged above, aligned with and connected to a corresponding one of said contiguous pair of through hole vias; and a two-port device mounted directly on said pair of octagonal conductive pads, in a given alignment with the grid pattern, wherein said contiguous pair octagonal conductive pads have respective sides aligned in a given alignment with the grid pattern.
