Patent ID: 7423885

Claim:
A circuit module comprising: a flexible circuit having a first major side and a second major side, the flexible circuit exhibiting along the first major side, first-side first and second sets of contact site arrays between which is located at least one row of connector contacts, the second major side of the flexible circuit exhibiting second-side first and second sets of contact site arrays which correspond to the first-side first and second sets of contact site arrays, each of the first-side and second-side first and second sets of contact site arrays comprising at least two surface mount arrays, the flexible circuit providing connections between the at least two surface mount arrays of each of the first-side first and second sets of contact site arrays and the at least two surface mount arrays of each of the second-side first and second sets of contact site arrays; first and second pluralities of flip-chip CSPs that populate the at least two surface mount arrays of each of the first-side first and second sets of contact site arrays and the at least two surface mount arrays of each of the second-side first and second sets of contact site arrays, respectively; a substrate comprised from metallic material and having an end about which the flexible circuit is disposed to place the second plurality of flip-chip CSPs closer to the substrate than are disposed the first plurality of flip-chip CSPs.
