Abstract:
A printed circuit board, comprising:first, second and third sets of connection points operable to be electrically connected to first, second and third integrated circuits, respectively;wherein the connection points in said first set of connection points are arranged in a first grid pattern, said first grid pattern having a generally rectangular shape, defining a first plane and having a first center at which first orthogonal axes intersect, said first orthogonal axes coplanar with said plane orthogonal to at least one edge of said first grid pattern;wherein the connection points in said second set of connection points are arranged in a second grid pattern, said second grid pattern having a generally rectangular shape, defining a second plane and having a second center at which second orthogonal axes intersect, said second orthogonal axes coplanar with said second plane and orthogonal to at least one edge of said grid pattern;wherein the connection points in said third connection points are arranged in a third grid pattern, said third grid pattern having a generally rectangular shape, defining a third plane and having a third center at which third orthogonal axes intersect, said third orthogonal axes coplanar with said third plane and orthogonal to at least one edge of said third grid pattern;wherein said first, second and third planes are parallel to one another; andwherein said second orthogonal axes are rotated counterclockwise relative to said first orthogonal axes by at least 5 degrees but not more than 25 degrees.
