Abstract
Abstract A resilient contact assembly for contacting a semiconductor device comprises a center segment and first and second side segments. The center segment has an open-ended pocket in the end thereof for receiving, positioning and supporting the semiconductor device. The ends of the side segment are bent out of the plane of the center segment and first and second contact arms extend therefrom towards said pocket to contact the semiconductor device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A resilient contact assembly for making contact through electrodes on the upper or lower surfaces of a semiconductor device, comprising: a center segment having an open-ended pocket at one end thereof for receiving, positioning and supporting said semiconductor device; first and second segments adjacent opposite sides of said central segment, the ends of said first and second segments approximate said pocket being bent out of the plane of said center segment; and first and second contact arms extending from the ends of said first and second segments toward said pocket.
Claim 2
Dependent Claim
90 words
A resilient contact assembly for making contact through electrodes on the upper or lower surfaces of a semiconductor device, comprising: a center segment having an open-ended pocket at one end thereof for receiving, positioning and supporting said semiconductor device; first and second segments adjacent opposite sides of said central segment, the ends of said first and second segments approximate said pocket being bent out of the plane of said center segment; and first and second contact arms extending from the ends of said first and second segments toward said pocket.
Claim 3
Dependent Claim
47 words
The resilient contact assembly according to claim 1 further comprising a plurality of groups of said center and side segments, each of said groups formed in a common elongated sheet of resilient metal, and laterally disposed with respect to one another and joined by a common connector.
Claim 4
Dependent Claim
38 words
A resilient contact assembly according to claim 1 wherein said first and second segments are longer than said center segment and the ends of said first and second segments are bent upward and generally back towards said pocket.
Claim 5
Dependent Claim
27 words
A resilient contact assembly according to claim 3 wherein said first and second contact arms terminate with a point for contacting the upper surface of said device.
Claim 6
Dependent Claim
26 words
A resilient contact assembly according to claim 4 wherein the tips of said points reside at a predetermined distance above the plane of said center segment.
