Patent ID: 7196908

Claim:
An electronic device, comprising: a substrate having an interior region having first, second, third, and fourth sides and a peripheral region having corresponding first, second, third and fourth edges, said first side opposite said second side, said third side opposite said fourth side each edge parallel to a corresponding side, and a center equidistant from said first and second sides and equidistant from said third and fourth sides, a first region of said interior region of said substrate defined by said first side and first and second diagonal lines from opposite ends of said first side to said center; a plurality of contacts pads arranged in rows and columns of contact pads on a surface of said interior region of said substrate, said rows of contact pads parallel to said first side, said columns of contact pads perpendicular to said rows; all adjacent columns of said columns of contacts pads spaced apart a same first predetermined distance; each of said rows of contact pads spaced apart a second predetermined distance, said first predetermined distance greater than said second predetermined distance; and except for contact pads immediately adjacent to said first side of said interior region of said substrate, each contact pad in each column of contact pads that is electrically connected to any wire is electrically connected to a wire that passes between contact pads of a column of contact pads that includes the contact pad to which said wire is connected and an adjacent column of said columns of contact pads and that crosses said first side of said interior region of said substrate.
