Abstract

Abstract An electrical connector (30) includes a body (34) of elastomeric material having cavities (38) containing a conductive gel (42) operable upon deformation of the body of said connector to interconnect conductive pads (14, 22) between components such as a printed circuit board (12) and a chip carrier (18). An alternative embodiment uses a connector body (34') comprised of a sheet (48) of a low thermal coefficient of expansion material with separate inserts (50) of a higher thermal coefficient of expansion fitted in sheet perforations (49).

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 165 words
An electrical connector adapted to interconnect first and second planar elements each having contact surfaces arrayed in a pattern extending over a given planar area, the said connector including a connector body formed of a planar sheet of material coextensive with the said given area and including an array of perforations in a pattern corresponding to the pattern of contact surfaces, an insert fitted in each perforation and extending out from the surface of the said sheet, each insert having a cavity containing a conductive gel of a volume less than the volume of the cavity, and further characterized in that the said insert is of an elastomeric material readily deformable to cause the said gel to flow axially to interconnect the first and second contact surfaces, the sheet being comprised of a material having a thermal coefficient of expansion comparable to the thermal coefficient of expansion of the said first and second planar elements whereby to minimize misalignment of element contact surfaces and inserts.
Claim 2
Dependent Claim 165 words
An electrical connector adapted to interconnect first and second planar elements each having contact surfaces arrayed in a pattern extending over a given planar area, the said connector including a connector body formed of a planar sheet of material coextensive with the said given area and including an array of perforations in a pattern corresponding to the pattern of contact surfaces, an insert fitted in each perforation and extending out from the surface of the said sheet, each insert having a cavity containing a conductive gel of a volume less than the volume of the cavity, and further characterized in that the said insert is of an elastomeric material readily deformable to cause the said gel to flow axially to interconnect the first and second contact surfaces, the sheet being comprised of a material having a thermal coefficient of expansion comparable to the thermal coefficient of expansion of the said first and second planar elements whereby to minimize misalignment of element contact surfaces and inserts.
Claim 3
Dependent Claim 30 words
The connector of claim 1 wherein the said sheet is an insulating material having a thermal coefficient of expansion on the order of less than 50 ppm per degree Centigrade.
Claim 4
Dependent Claim 26 words
The connector of claim 1 wherein the said sheet is of a material having a thermal coefficient on the order of 20 ppm per degree Centigrade.
Claim 5
Dependent Claim 38 words
The connector of claim 1 wherein the said insert is of a material having physical characteristics comparable to liquid silicon rubber and the sheet is of a material having physical characteristics comparable to a liquid crystal polymer material.
