Abstract
Abstract A carrier for an integrated circuit package is disclosed which comprises a base (30) suitable for receiving an integrated circuit package with unformed leads (20') or formed leads (20), a cover (60), flexible material (66), such as an elastomer, disposed between the cover (60) and base (30) surfaces, and pressure is maintained across the cover (60) and base (30) by way of finger (44) on a clip (40) on the base (30) engaging latching edges (68) of cover (60). The leads (22) of the integrated circuit package (20, 20') are thereby secured in position by the elastomeric material (66) which forms itself partially around each of the leads in response to pressure applied across the base (30) and cover (60) as hereinabove described. The disclosed invention eliminates the need for separate grooves or nests in the base (30) of the carrier for each lead of the integrated circuit package.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
An integrated circuit carrier comprising: a rectangular-shaped base with a supporting platform containing a rectangular-shaped indentation disposed in the platform and an elastomeric material permanently affixed in a recessed groove on a top portion of said base; a rectangular-shaped cover; and means for securing an integrated circuit having leads between said base and said cover, whereby the leads of an integrated circuit package suitably disposed between said base and said cover are secured in position by the flexible material which forms itself partially around each of the leads in response to pressure across said base and said cover imposed by said securing means.
Claim 2
Dependent Claim
103 words
An integrated circuit carrier comprising: a rectangular-shaped base with a supporting platform containing a rectangular-shaped indentation disposed in the platform and an elastomeric material permanently affixed in a recessed groove on a top portion of said base; a rectangular-shaped cover; and means for securing an integrated circuit having leads between said base and said cover, whereby the leads of an integrated circuit package suitably disposed between said base and said cover are secured in position by the flexible material which forms itself partially around each of the leads in response to pressure across said base and said cover imposed by said securing means.
Claim 3
Dependent Claim
146 words
A carrier for a high-lead density electronic integrated circuit package comprising: a rectangular-shaped base with a supporting platform containing a rectangular-shaped indentation in the platform; a rectangular-shaped cover containing a grooved recess along a bottom portion of said cover with a flexible material permanently affixed in said grooved recess; and means for securing said base to said cover consisting of clips disposed on said base and latching edges in said cover whereby said clips insert into said edges and said protruding clips contain a finger member perpendicularly disposed to a longitudinal clip axis at the top of said clip whereby said finger member has sloping faces, and whereby the leads of an integrated circuit package suitably disposed between said base and said cover are secured in position by said flexible material which forms itself partially around each of the leads in connection of said securing means.
Claim 4
Dependent Claim
146 words
