Abstract
Abstract A contact bump is formed on a sheet of electrically-conductive material by plastically deforming the sheet so as to form a depression at one side of the sheet and a corresponding bump at the opposite side of the sheet. Solid material is placed in the depression, and the sheet of electrically-conductive material is secured at its one side to a support member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
65 words
A method of forming a contact bump on a sheet of electrically-conductive material, comprising: (a) plastically deforming the sheet of electrically-conductive material so as to form a depression on one side of the sheet and a corresponding protrusion on the opposite side thereof, (b) placing solid material in the depression, and (c) securing the sheet of electrically-conductive material to a support member of elastomeric material.
Claim 2
Independent Claim
65 words
A method of forming a contact bump on a sheet of electrically-conductive material, comprising: (a) plastically deforming the sheet of electrically-conductive material so as to form a depression on one side of the sheet and a corresponding protrusion on the opposite side thereof, (b) placing solid material in the depression, and (c) securing the sheet of electrically-conductive material to a support member of elastomeric material.
Claim 3
Dependent Claim
25 words
A method according to claim 1, further comprising: (d) selectively removing portions of the sheet of electrically-conductive material from the support member of elastomeric material.
Claim 4
Dependent Claim
20 words
A method according to claim 2, wherein step (d) comprises removing portions of the sheet of electrically-conductive material by etching.
Claim 5
Independent Claim
81 words
A method of forming a contact bump on a sheet of electrically-conductive material, comprising: (a) plastically deforming the sheet of electrically-conductive material so as to form a depression on one side of the sheet and a corresponding protrusion on the opposite side thereof, (b) placing solid material in the depression, (c) securing the sheet of electrically-conductive material to a sheet-form support member of flexible material, and (d) securing the sheet-form support member of flexible material to a body of elastomeric material.
Claim 6
Independent Claim
81 words
A method of forming a contact bump on a sheet of electrically-conductive material, comprising: (a) plastically deforming the sheet of electrically-conductive material so as to form a depression on one side of the sheet and a corresponding protrusion on the opposite side thereof, (b) placing solid material in the depression, (c) securing the sheet of electrically-conductive material to a sheet-form support member of flexible material, and (d) securing the sheet-form support member of flexible material to a body of elastomeric material.
