Abstract
Abstract An integrated circuit package includes conductors (3) bonded between a cover (9) and a base (13) which has a cavity (14) in which a chip (12) is received. Each conductor (3) joins an attach pad (1) which protrudes into the cavity (14) with a contact (2) which projects (7, 8) through a window (10) in the cover (9). When bolted (20) to a printed circuit board (16), the contact projections (7, 8) make contact with contact areas (18) on the board.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
94 words
A carrier for an electrical integrated circuit chip comprising conductive strips of resilient material secured between a base of insulating material and a cover of insulating material, the base having a cavity in which a chip can be received, each conductive strip having an attach pad at one end of the strip and a contact at the other end of the strip, the attach pad protruding into the cavity and the contact risingclear-of the base by a distance exceeding the thickness of the cover, and the cover having windows through which the contacts project.
Claim 2
Dependent Claim
94 words
A carrier for an electrical integrated circuit chip comprising conductive strips of resilient material secured between a base of insulating material and a cover of insulating material, the base having a cavity in which a chip can be received, each conductive strip having an attach pad at one end of the strip and a contact at the other end of the strip, the attach pad protruding into the cavity and the contact risingclear-of the base by a distance exceeding the thickness of the cover, and the cover having windows through which the contacts project.
Claim 3
Dependent Claim
38 words
A carrier as claimed in claim 1 in which the conductive strips are bonded to the base and cover, and in which a contact comprises twin crests spaced from each other along the length of the conductive strip.
Claim 4
Dependent Claim
58 words
A carrier as claimed in claim 1 in which the cavity penetrates the thickness of the base to form a hole, in which the base has a surface depression forming a platform around the hole, and in which the conductive strips are sHanked to conform with the depression and to present attach pads which rest on the platform.
Claim 5
Dependent Claim
22 words
A carrier as claimed in claim 1 which includes studs by which the carrier may be bolted to a printed circuit board.
