A method and apparatus for electrically connecting two substrates using resilient wire bundles captured in apertures of an interposer by a retention film. The interposer comprises an electrically non-conductive carrier having two surfaces and apertures extending from surface to surface. A resilient wire bundle is disposed in each aperture. An electrically non-conductive retention film is associated with one or both surfaces of the carrier and has an orifice overlying each aperture. The width of each orifice is smaller than that of the underlying aperture to thereby enhance retention of the resilient wire bundle within the aperture. Pin contacts of one or both of the substrates make electrical contact with the resilient wire bundles by extending through the orifices of the retention film and partially through the apertures. In one embodiment, the interposer is a land grid array (LGA) connector that connects an electronic module and a printed circuit board (PCB).

What is claimed is: 1. An interposer, comprising: an electrically non-conductive carrier having a first surface and a second surface, and an aperture extending from the first surface to the second surface; an electrically non-conductive first retention member mounted on the first surface of the carrier and having an orifice overlying the aperture of the carrier, wherein the orifice of the first retention member has a width smaller than that of the aperture of the carrier: a resilient wire bundle disposed in the aperture of the carrier; wherein the first retention member comprises a polyimide film. 2. An interposer, comprising: an electrically non-conductive carrier having a first surface and a second surface, and an aperture extending from the first surface to the second surface; an electrically non-conductive first retention member mounted on the first surface of the carrier and having an orifice overlying the aperture of the carrier, wherein the orifice of the first retention member has a width smaller than that of the aperture of the carrier; an electrically non-conductive second retention member mounted on the second surface of the carrier and having an orifice underlying the aperture of the carrier, wherein the orifice of the second retention member has a width smaller than that of the aperture of the carrier; a resilient wire bundle disposed in the aperture of the carrier; wherein the first and second retention members each comprises a polyimide film. 3. An interposer comprising: an electrically non-conductive carrier having a first surface and a second surface, and a plurality of apertures arranged in an array and extending from the first surface to the second surface; an electrically non-conductive first retention member mounted on the first surface of the carrier and having a plurality of orifices overlying the apertures of the carrier, wherein each orifice of the first retention member has a width smaller than that of the underlying aperture of the carrier; an electrically non-conductive second retention member mounted on the second surface of the carrier and having a plurality of orifices underlying the apertures of the carrier, wherein each orifice of the second retention member has a width smaller than that of the overlying aperture of the carrier; a plurality of resilient wire bundles disposed in the apertures of the carrier; wherein the first and second retention members each comprises a polyimide film. 4. The interposer as recited in claim 3, wherein the polyimide film has a thickness of about 0.006 inch. 5. A connector assembly, comprising: a first substrate having a pin contact on a surface thereof; a second substrate having a contact on a surface thereof; an interposer disposed between the first and second substrates, wherein the interposer includes an electrically non-conductive carrier having a first surface and a second surface, and an aperture extending from the first surface to the second surface, an electrically non-conductive first retention member associated with the first surface of the carrier and having an orifice overlying the aperture of the carrier, wherein the orifice of the first retention member has a width smaller than that of the aperture of the carrier, and a resilient wire bundle disposed in the aperture of the carrier; a clamping mechanism that applies a force that urges the first and second substrates toward each other; wherein the pin contact of the first substrate makes electrical contact with the resilient wire bundle by extending through the orifice of the first retention member and partially through the aperture of the carrier; wherein the contact of the second substrate makes electrical contact with the resilient wire bundle. 6. The connector assembly as recited in claim 5, wherein the first retention member comprises a polyimide film. 7. The connector assembly as recited in claim 5, wherein the interposer further includes an electrically non-conductive second retention member associated with the second surface of the carrier and having an orifice underlying the aperture of the carrier, wherein the orifice of the second retention member has a width smaller than that of the aperture of the carrier. 8. The connector assembly as recited in claim 7, wherein the first and second retention members each comprises a polyimide film. 9. The connector assembly as recited in claim 5, wherein a stop member extends between the interposer and the first substrate. 10. The connector assembly as recited in claim 5, wherein the first substrate is an electronic module and the second substrate is a printed circuit board (PCB), the carrier includes a plurality of the apertures arranged in an array, the first retention member has a plurality of the orifices, and a plurality of the resilient wire bundles are disposed in the apertures of the carrier. 11. The connector assembly as recited in claim 10, wherein the interposer further includes an electrically non-conductive second retention member associated with the second surface of the carrier and having a plurality of orifices underlying the apertures of the carrier, wherein the each orifice of the second retention member has a width smaller than that of the overlying aperture of the carrier. 12. The connector assembly as recited in claim 11, wherein the first and second retention members each comprises a polyimide film. 13. The connector assembly as recited in claim 5, wherein the pin contact and the orifice of the first retention member are dimensioned for a slight interference fit.
