An interposer assembly includes a dielectric plate having a plurality of contact passages extending through the plate with a contact in each passage. Each contact includes a pair of laterally spaced contact points at the top and bottom of the plate. Sandwiching of the interposer assembly between two substrates brings the contact points on each spring arm into engagement with a pad, elastically bends the contacts and forms redundant high pressure wiped electrical connections between the contact points and pads.

1. An interposer assembly for forming redundant electrical connections with contact pads on substrates positioned above and below the assembly, said assembly comprising:a) an insulating plate having top and bottom sides and a plurality of passages extending through the thickness of the plate; and b) a plurality of metal contacts, each contact disposed in one of said passages, each contact including a first pair of spaced contact points at the top side of the plate, a second pair of spaced contact points at the bottom side of the plate, and a spring portion extending between said first pair of contact points and said second pair of contact points, said spring portion spacing said pairs of contact points apart a distance greater than the thickness of the plate when the spring portion is unstressed; each contact formed from uniform thickness strip stock having a first sheared edge, and at least one contact point comprises a shear-rounded corner of said edge located above the adjacent surface of the metal contact; wherein the shear rounded corner forms an electrical connection with a pad. 2. The assembly as in claim 1 wherein each spring portion includes a central portion and a pair of beams, each beam located between the central portion and a pair of contact points, said beams elastically bendable into said passages.3. The assembly as in claim 2 wherein each contact point is bent to one side of a beam.4. The assembly as in claim 3 wherein each contact point is rounded along the length of a beam.5. The assembly as in claim 4 wherein said strip stock has a thickness of about 0.0017 inches.6. The assembly as in claim 4 wherein each contact point comprises a shear-rounded corner and said rounded corners have a radius of curvature of about 0.0006 to 0.0010 inches.7. The assembly as in claim 4 wherein each contact is symmetrical to either side of the central portion.8. The assembly as in claim 7 wherein the plate includes a projection extending into each passage, and each contact includes two retention portions located on opposite sides of a projection to retain the contact in the passage.9. The assembly as in claim 1 wherein each contact includes a second sheared edge, each contact point comprising a shear-rounded edge corner.10. The assembly as in claim 9 wherein each contact point comprises a bent projection.11. An assembly adapted to be interposed between pairs of spaced metallic pads on substrates for forming electrical connections between the pads, said assembly comprising:a) a dielectric plate having a top and a bottom, a plurality of spaced passages extending through the thickness of the plate from said top to said bottom thereof, said passages each including opposed interior walls, b) a projection in each passage, each projection extending outwardly from one of said interior walls toward an opposed interior wall and including a first surface facing said plate top and a second surface facing said plate bottom; c) a plurality of metal contacts, each contact disposed in one of said passages, each contact formed from thin sheet metal stock and including a central portion, a pair of beams extending to either side of the central portion, a nose located on the end of each beam, and a retention leg extending inwardly from each nose to an end located away from the central portion, said noses spaced apart a distance greater than the thickness of the plate when the contact is unstressed, each contact being located in a passage with the central portion adjacent an interior wall away from the passage projection and the ends of the retention legs located on opposite sides of the projection so that the projection retains the contact in the passage; and d) each contact including a pair of laterally spaced contact points adjacent each contact nose; e) wherein upon compression of the contacts into the passages by opposed contact pads, the beams are stressed, and the contact points on each nose engage and wipe along a pad to form redundant wiped pressure connections with the pad. 12. The assembly as in claim 11 wherein said beams are curved.13. The assembly as in claim 12 wherein each contact point is located on an edge of a beam adjacent a nose.14. The assembly as in claim 13 wherein each contact point is located at a corner of a beam edge.15. The assembly as in claim 11 wherein at least one contact point comprises a shear-wiped corner of a beam edge.16. The assembly as in claim 14 wherein said strip stock has a thickness of about 0.0017 inch.17. The assembly as in claim 16 wherein said contact points are rounded and have a radius of curvature of about 0.006 inches.18. The assembly as in claim 11 wherein each contact point comprises a portion of a contact bent to one side of the remainder of the contact.19. The assembly as in claim 11 wherein said beams are tapered.20. The assembly as in claim 11 wherein said retention legs are tapered.21. An interposer assembly comprising:a) an insulating plate having top and bottom sides and a plurality of passages extending through the thickness of the plate; b) a plurality of elongate metal contacts, each contact formed from thin sheet metal having opposed longitudinally extending sheared edges and including a pair of spaced apart curved noses, and a spring located between the noses, each nose extending across the width of the contact between such sheared edges and including a shear-rounded edge corner at each sheared edge, the edge corners facing outwardly of the assembly and located above the surface of the nose between said edge corners, said edge corners being rounded along the length of the contacts; and c) each contact located in a passage in the plate with said noses adjacent the top and bottom sides of the plate and spaced apart a distance greater than the thickness of the plate when the contacts are unstressed; wherein the shear-rounded edge corners at each hose form redundant electrical connections with contact pads on substrates overlying and underlying the plate. 22. An interposer assembly as in claim 21 wherein said beams are curved.23. An interposer assembly as in claim 21 wherein each contact point is bent up from one side of a contact end.
