Electrical connectors capable of being mounted on circuit substrates by BGA techniques are disclosed. Also, disclosed is a method of manufacturing such connectors. There is at least one recess on the exterior side of the connector elements. A conductive contact extends from adjacent the interior side into the recess on the exterior side of the housing. A controlled volume of solder paste is introduced into the recess. A fusible conductive element, in the form of solder balls is positioned in the recess. The connector is subjected to a reflow process to fuse the solder ball to the portions of the contact extending into said recess. Contacts are secured in the insulative housing of the connector by deformable sections that minimize stress imposed on the central portions of the contacts to promote uniformity of solder volume.
What is claimed is: 1. An electrical connector comprising: an insulative housing that defines a recess and an exterior surface adjacent to the recess; an electrical contact on the insulative housing, wherein the electrical contact defines a tab with a free end and the tab is positioned in the reces
What is claimed is: 1. An electrical connector comprising: an insulative housing that defines a recess and an exterior surface adjacent to the recess; an electrical contact on the insulative housing, wherein the electrical contact defines a tab with a free end and the tab is positioned in the recess; and a body of reflowable, electrically conductive material positioned at least partially within the recess, wherein the recess is defined by the housing and not by a solder resist layer on the exterior surface of the insulative housing. 2. The electrical connector as claimed in claim 1 wherein the body of reflowable, electrically conductive material is a solder ball. 3. The electrical connector as claimed in claim 1, wherein the electrical contact has a medial portion and the medial portion has an ant-wicking material thereon. 4. A method of making an electrical connector adapted to be mounted to a substrate and having a substrate mounting side and a mating side comprising: providing an insulative member that defines a first surface that corresponds to the mating side of the connector and a second surface that corresponds to the substrate mounting side of the connector; providing an electrically conductive contact on the insulative member, wherein a section of the contact extends into the insulative member and a portion of the contact is positioned adjacent to the second surface; providing a recess at the substrate mounting side of the connector on the portion of the contact that is positioned adjacent to the second surface; positioning a substantially spherical electrically conductive element in the recess in the absence of a solder resist layer on the second surface of the insulative member; and reflowing the electrically conductive element to the portion of the contact that is positioned adjacent to the second surface. 5. The method of claim 4, further comprising the step of placing an anti-wicking material on a medial portion of the contact, adjacent to the portion of the contact that is positioned adjacent to the second surface. 6. The method of claim 4, further comprising the step of bending the portion of the contact to define a tab with a free end. 7. The method of claim 5, further comprising the step of bending the portion of the contact to define a tab with a free end. 8. The electrical connector of claim 7, wherein the tab is a bent end of the electrical contact. 9. A method of making an electrical connector adapted to be mounted to a substrate and having a substrate mounting side and a mating side comprising: providing an insulative member that defines a first surface that corresponds to the mating side of the connector and a second surface that corresponds to the substrate mounting side of the connector; providing an electrically conductive contact on the insulative member, wherein a section of the contact extends into the insulative member, a portion of the contact defines a tab with a free end, and the tab is positioned adjacent to the second surface; providing a recess at the substrate mounting side of the connector; positioning a substantially spherical electrically conductive element in the recess in the absence of a solder resist layer on the second surface of the insulative member; and reflowing the electrically conductive element onto the tab. 10. The method of claim 9, further comprising the step of placing an anti-wicking material on a medial portion of the contact, adjacent to the tab. 11. The method of claim 9, further comprising the step of bending the portion of the contact to define the tab. 12. The method of claim 9, wherein the step of providing a recess at the substrate mounting side of the connector comprises the step of defining the recess on the tab. 13. The method of claim 9, wherein the step of providing a recess at the substrate mounting side of the connector comprises the step of defining the recess on the second side of the insulative member. 14. The method of claim 10, wherein the step of providing a recess at the substrate mounting side of the connector comprises the step of defining the recess on the tab. 15. The method of claim 10, wherein the step of providing a recess at the substrate mounting side of the connector comprises the step of defining the recess on the second side of the insulative member.
