What is claimed is: 1. An electrical connector, comprising: a first circuit board having a face and having a plurality of signal conductors disposed on the face of the first circuit board; a second circuit board having a face and having a plurality of signal conductors disposed on the face of the second circuit board; a spacer having a first face and a second face opposite the first space, wherein the spacer is disposed directly between the first circuit board and the second circuit board such that the first face of the spacer abuts the face of the first circuit board and the second face of the spacer abuts the face of the second circuit board, the number of signal conductors disposed on the face of the first circuit board is equal to M; the first face of the spacer has a set of at least M grooves formed thereon, each one of the M grooves mirroring a different one of the M signal conductors disposed on the face of the first circuit board, the number of signal conductors disposed on the face of the second circuit board is equal to N; the second face of the spacer having a set of at least N grooves disposed thereon, each one of the N grooves mirroring a different one of the N signal conductors, and none of the at least N grooves mirror any one of the at least M grooves. 2. The electrical connector of claim 1, wherein each of the M grooves extends from a first edge of the first face to a second edge of the first face, and each of the N grooves extends from a first edge of the second face to a second edge of the second face. 3. The electrical connector of claim 1, wherein each of the M signal conductors extends from a first edge of the face of the first circuit board to a second edge of the face of the first circuit board, and each of the N signal conductors extends from a first edge of the face of the second circuit board to a second edge of the face of the second circuit board. 4. The electrical connector of claim 1, further comprising an interposer. 5. The electrical connector of claim 4, wherein the spacer has an elongate finger projecting outwardly from a side of the spacer for attaching the spacer to the interposer. 6. The electrical connector of claim 5, further comprising a second interposer. 7. The electrical connector of claim 6, wherein the spacer has a second elongate finger projecting outwardly from a second side of the spacer for attaching the spacer to the second interposer. 8. The electrical connector of claim 7, wherein the first interposer has a recess for receiving an end of the first elongate finger and the second interposer has a recess for receiving an end of the second elongate finger, the first finger has protrusion located at said end of the first finger, and the second finger has protrusion located at said end of the second finger. 9. The electrical connector of claim 1, wherein N is less than M. 10. The electrical connector of claim 1, wherein N is equal to M. 11. A method for assembling an electrical connector, comprising: obtaining a first circuit board having a face and having a plurality of signal conductors disposed on the face of the first circuit board, wherein the number of signal conductors disposed on the face of the first circuit board is equal to M; obtaining a second circuit board having a face and having a plurality of signal conductors disposed on the face of the second circuit board, wherein the number of signal conductors disposed on the face of the second circuit board is equal to N; obtaining a spacer having a first face and a second face opposite the first space, wherein the first face of the spacer has a set of at least M grooves formed thereon, the second face of the spacer has a set of at least N grooves disposed thereon, and none of the at least N grooves mirror any one of the at least M grooves; and disposing the spacer directly between the first circuit board and the second circuit board such that: the first face of the spacer abuts the face of the first circuit board and the second face of the spacer abuts the face of the second circuit board, each one of the M grooves receives a different one of the M signal conductors, each one of the N grooves receives a different one of the N signal conductors. 12. The method of claim 11, wherein each of the M grooves extends from a first edge of the first face to a second edge of the first face, and each of the N grooves extends from a first edge of the second face to a second edge of the second face. 13. The method of claim 11, wherein each of the M signal conductors extends from a first edge of the face of the first circuit board to a second edge of the face of the first circuit board, and each of the N signal conductors extends from a first edge of the face of the second circuit board to a second edge of the face of the second circuit board. 14. The method of claim 11, further comprising obtaining an interposer. 15. The method of claim 14, wherein the spacer has an elongate finger projecting outwardly from a side of the spacer for attaching the spacer to the interposer. 16. The method of claim 15, further comprising obtaining a second interposer. 17. The method of claim 16, wherein the spacer has a second elongate finger projecting outwardly from a second side of the spacer for attaching the spacer to the second interposer. 18. The method of claim 17, wherein the first interposer has a recess for receiving an end of the first elongate finger and the second interposer has a recess for receiving an end of the second elongate finger, the first finger has protrusion located at said end of the first finger, and the second finger has protrusion located at said end of the second finger. 19. The method of claim 11, wherein N is less than M. 20. The method of claim 11, wherein N is equal to M.
