The invention claimed is: 1. A method of electrically connecting an electronic device to a substrate, said method comprising: passing free ends of a plurality of elongate spring contacts attached to said electronic device into a plurality of rigid, conductive recesses in a first surface of said substrate, each said recess comprising a bottom portion disposed within said substrate that prevents said free ends from passing through said substrate, conductive elements providing electrical paths from said recesses to a second surface of said substrate; and applying a force to said electronic device and thereby pressing said free ends against said bottom portions of said rigid, conductive recesses, wherein electrical connections between said elongate spring contacts and said rigid, conductive recesses are established and maintained substantially entirely due to said pressing, wherein for each said conductive recess, each portion of said conductive recess is electrically connected to every other portion of said conductive recess. 2. The method of claim 1, wherein said electronic device comprises a semiconductor device. 3. The method of claim 2, wherein said semiconductor device comprises a semiconductor die comprising an integrated electronic circuit. 4. The method of claim 1, wherein each of said recesses is V shaped. 5. The method of claim 1, wherein each of said recesses is U shaped. 6. The method of claim 1, wherein each of said recesses is trapezoidal shaped. 7. The method of claim 1, wherein each of said recesses is wider near a surface of said substrate than within said substrate. 8. The method of claim 1, wherein each of said recesses extends into said substrate and is tapered inwardly. 9. The method of claim 1 further comprising removing said force, wherein said electrical connections are substantially eliminated. 10. The method of claim 1, wherein each said recess comprises a cavity in said substrate, wherein said cavity comprises said bottom portion of each said recess. 11. The method of claim 1, wherein each said recess comprises: a cavity in said substrate, and a metallic plating disposed on a surface of said cavity, wherein said bottom portion of each said recess comprises said plating. 12. The method of claim 1, wherein said substrate comprises a second electronic device to which said electronic device is electrically connected by said electrical connections between said elongate spring contact and said recesses. 13. The method of claim 1, wherein said bottom portion of said recess comprises a plated portion of said substrate. 14. The method of claim 1, wherein: said elongate spring contacts are electrically conductive; said recesses are electrically conductive; and said bottoms of said recesses are electrically conductive. 15. The method of claim 1, wherein each said recess comprises side walls extending from a surface of said substrate to said bottom portion, wherein said side walls are electrically conductive and electrically connected to said bottom portion. 16. The method of claim 1, wherein each of said conductive elements extends from one of said bottom portions of said recesses to said second surface, and said second surface is opposite said first surface. 17. A method of electrically connecting an electronic device to a substrate, said method comprising: providing an electronic device having a plurality of elongate, spring contact elements for providing signal inputs to and/or outputs from said electronic device; and pressing tips of ones of said spring contact elements against rigid conductive terminals disposed adjacent a first surface of said substrate, conductive elements providing electrical paths from said terminals to a second surface of said substrate, said pressing compressing said spring contact elements and generating in said spring contact elements spring reaction forces that are perpendicular with respect to said first surface of said substrate, wherein electrical connections between said elongate spring contacts and said rigid terminals are established and maintained substantially entirely due to said pressing, wherein each said terminal comprises a recess that comprises electrically conductive side walls and an electrically conductive bottom portion, said side walls extending from a surface of said substrate to said bottom portion, wherein said side walls are electrically connected to said bottom portion. 18. The method of claim 17, wherein said electrical connections are substantially eliminated by ceasing said pressing step. 19. The method claim 17, wherein said electronic device comprises a semiconductor device. 20. The method of claim 19, wherein said semiconductor device comprises a semiconductor die comprising an integrated electronic circuit. 21. The method of claim 17, wherein: said spring contacts are electrically conductive; and said terminals are electrically conductive. 22. The method of claim 17, wherein: said step of pressing comprises passing said tips through said recesses. 23. The method of claim 22, wherein said pressing comprises pressing said tips against said bottom portions of said recesses. 24. The method of claim 23, wherein each of said conductive elements extends from one of said bottoms of said recesses to said second surface, and said second surface is opposite said first surface. 25. The method of claim 1, wherein the passing step comprises passing each one of said free ends of said spring contacts into a different one of said recesses. 26. The method of claim 23, wherein said bottom prevents said tips from passing through said substrate. 27. The method of claim 26, wherein said recesses are cone shaped. 28. The method of claim 26, wherein said recesses are concave. 29. The method of claim 26, wherein each of said recesses is V shaped. 30. The method of claim 26, wherein each of said recesses is U shaped. 31. The method of claim 26, wherein each of said recesses is trapezoidal shaped. 32. The method of claim 26, wherein each of said recesses is wider near a surface of said substrate than within said substrate. 33. The method of claim 26, wherein each of said recesses extends into said substrate and is tapered inwardly. 34. The method of claim 26, wherein each said recess comprises a cavity in said substrate, wherein said cavity comprises said bottom portion of each said recess. 35. The method of claim 26, wherein each said recess comprises: a cavity in said substrate, and a metallic plating disposed on a surface of said cavity, wherein said bottom portion of each said recess comprises said plating. 36. The method of claim 26, wherein said substrate comprises a second electronic device to which said electronic device is electrically connected by said electrical connections between said elongate spring contact and said terminals. 37. The method of claim 26, wherein said bottom portion of said recess comprises a plated portion of said substrate. 38. The method of claim 26, wherein: said elongate spring contact elements are electrically conductive; said recesses are electrically conductive; and said bottoms of said recesses are electrically conductive.
