A modular board to board mezzanine ball grid array BGA connector includes a plug, a receptacle and if needed an adapter. The plug and the receptacle can be made form the same base pieces to accommodate different stack heights. If a greater stack height is needed, spacers can be used in the plug and the receptacle to accommodates a greater selected stack height. The plug and the receptacle both include a base having an interstitial diamond recesses in which the solder balls are disposed and in which one end of a contact is inserted. The plug may further include a plug cover that can be connected to the base, and the receptacle may include a receptacle cover that fits over its base. The plug can have a plug contact assembly, and the receptacle can have a receptacle contact assembly. The plug and the receptacle can be mated by mating the plug cover to the receptacle cover and the receptacle contacts to the plug contacts. If a larger stack height is desired, a spacer can be attached to the base of either or both the plug or the receptacle to achieve a larger stack height.

What is claimed is: 1. An electrical connector, comprising: a base having a plurality of recesses formed therein; a contact assembly comprising a plurality of electrical contacts and a carrier molded onto the plurality of electrical contacts, the carrier being mounted on the base so that the each of the plurality of electrical contacts extends through one of the plurality of recesses; and a plurality of fusible elements, each of the plurality of fusible elements being attached to an end of each of the plurality of contacts, wherein each of the plurality of fusible elements is positioned on one side of the base, and the carrier is positioned on an opposite side of the base, so that a portion of the base is positioned between the carrier and the ends of each of the plurality of contacts where the fusible elements are attached. 2. The electrical connector of claim 1, wherein each of the plurality of fusible elements is positioned adjacent the base. 3. The electrical connector of claim 1, wherein each of the plurality of recesses is formed by two pairs of opposing angled walls. 4. The electrical connector of claim 1, wherein the base has a plurality of pockets formed in a bottom thereof, each of the plurality of pockets adjoining one of the plurality of recesses, each of the plurality of fusible elements being positioned at least partly within one of the plurality of pockets. 5. The electrical connector of claim 1, wherein the plurality of electrical contacts arranged in a linear array, and the electrical connector comprises a plurality of the contact assemblies. 6. The electrical connector of claim 1, further comprising a cover for mating with the base and receiving at least a portion of each of the plurality of electrical contacts. 7. The electrical connector of claim 1, wherein the plurality of fusible elements are solder balls. 8. The electrical connector of claim 1, farther comprising a spacer for mating with the base and receiving at least a portion of each of the plurality of electrical contacts. 9. The electrical connector of claim 8, farther comprising a cover for mating with the spacer and receiving another portion of each of the plurality of electrical contacts. 10. The electrical connector of claim 1, wherein the base has slots formed therein for receiving ends of the contact assembly. 11. The electrical connector of claim 10, further comprising a spacer for mating with the base, the spacer having grooves formed therein for receiving the ends of the electrical contact assembly. 12. An electrical connector, comprising: a base having a through hole formed therein; a contact assembly comprising an electrical contact and a carrier molded onto the electrical contact; a spacer for mating with the base, the spacer having a groove adapted to receive the contact assembly; wherein the contact assembly is mounted on at least one of the spacer and the base so that a portion of the electrical contact extends through the through hole; a fusible element attached to the electrical contact adjacent the base so that the fusible element is positioned on one side of the base, the carrier is positioned on an opposite side of the base, and a portion of the base is positioned between the fusible element and the carner. 13. The electrical connector of claim 12, further comprising a cover for mating with the spacer. 14. The electrical connector of claim 12, wherein the contact assembly comprises a plurality of the electrical contacts arranged in a linear array, and the electrical connector comprises a plurality of the contact assemblies. 15. The electrical connector of claim 12, wherein the through hole is a recess is formed by two pairs of opposing angled walls. 16. The electrical connector of claim 15, wherein the base has a pocket formed in a bottom thereof and adjoining the recess, and the fusible element is positioned at least in part within the pocket. 17. An electrical connector, comprising: a contact assembly comprising an electrical contact and a carrier molded over at least a portion of the electrical contact; a base having a recess extending between a first and a second surface of the base for receiving a first portion of the electrical contact; at least one of a spacer and a cover mechanically coupled to the base the spacer having a groove formed therein for receiving a contact assembly, the cover having a slot formed therein for receiving a second portion of the contact; and a fusible element attached to an end of the electrical contact adjacent the second surface of the base, wherein the fusible element is positioned on one side of the base and the carrier is positioned on an opposite side of the base so that a portion of the base is positioned between the fusible element and the carrier. 18. The electrical connector of claim 17, wherein the carrier is positioned adjacent the first surface of the base.
