Abstract:
1. A method for providing electrical connections for an area array device, the method comprising: forming a plurality of holes within a circuit board, each hole comprising a conductor within the hole and an opening on a side of the circuit board; forming a plurality of electrically conductive contact posts; forming a compliant portion on an end of each contact post, the compliant portion sized for compressible insertion within one of the holes; forming a spring portion on an opposite end of each contact post, the spring portion compressible toward the compliant portion; inserting the compliant portion of the plurality of contact posts into the openings of at least a portion of the plurality of holes in a pattern corresponding to contact pads disposed on an area array device such that the conductors within the holes compress the compliant portions to removably secure the contact posts within the holes and provide electrical connections between the contact posts and the conductors, the spring portions extending away from the circuit board and compressible toward the circuit board in response to contact with the contact pads of the area array device, the spring portions providing electrical connections between the contact posts and the contact pads in response to the contact with the contact pad; and inserting a second plurality of electrically conductive contact posts into opposite openings of at least a portion of the plurality of holes, the opposite openings disposed in an opposite side of the circuit board, the second plurality of contact posts disposed in a pattern corresponding to contact pads disposed on a second area array device, electrically connecting one or more of the plurality of electrically conductive contact posts to one or more of the second plurality of electrically conductive contact posts extending from different holes of the plurality of holes, the circuit board comprising an interposer between the area array device and the second area array device.
