Abstract
Abstract A carrier and test device 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 materials (66), such as an elastomeric, disposed between the cover (60) and base (30) surfaces, and a means (40, 44, 68) for maintaining pressure across the cover (60) and base (30). 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) by the securing means (40, 44, 68). The disclosed invention eliminates the need for separate grooves or nests in the base (30) of the carrier and test device (10) for each lead of the integrated circuit package while providing a means to test the IC package while in the carrier and test device (10).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
A carrier for an integrated circuit package having protruding leads, said carrier comprising: a base suitable for receiving the integrated circuit package such that the leads extend over base support surfaces having openings therethrough; a cover having surfaces in alignment with said base support surfaces; elastomeric connector material disposed in said openings in said base support surfaces and extending therethrough; and means for maintaining pressure across said cover and base; whereby the leads of an integrated circuit package suitably disposed between said base and said cover are secured in position by the elastomeric connector material which forms itself partially around each of the leads in response to the pressure across said base and said cover and the elastomeric material protruding from the bottom of said base is adapted for use in electrical testing of the integrated circuit.
Claim 2
Dependent Claim
137 words
A carrier for an integrated circuit package having protruding leads, said carrier comprising: a base suitable for receiving the integrated circuit package such that the leads extend over base support surfaces having openings therethrough; a cover having surfaces in alignment with said base support surfaces; elastomeric connector material disposed in said openings in said base support surfaces and extending therethrough; and means for maintaining pressure across said cover and base; whereby the leads of an integrated circuit package suitably disposed between said base and said cover are secured in position by the elastomeric connector material which forms itself partially around each of the leads in response to the pressure across said base and said cover and the elastomeric material protruding from the bottom of said base is adapted for use in electrical testing of the integrated circuit.
Claim 3
Dependent Claim
135 words
A carrier and test arrangement for an integrated circuit package having protruding leads, said carrier comprising: a base suitable for receiving the integrated circuit package such that the leads are supported on surfaces thereof with openings through said base at said base surfaces; a cover having surfaces in alignment with said base support surfaces; elastomeric connector material disposed in said openings in said base and extending therethrough; means for maintaining pressure across said cover and base; and a device under test board having circuitry to match the pattern and density of the integrated circuit package lead configuration, so that when the base is aligned on the device under test board the elastomeric connector electrical paths make contact with the circuitry on the device under test board creating a unique electrical circuit to each package lead.
Claim 4
Dependent Claim
135 words
A carrier and test arrangement for an integrated circuit package having protruding leads, said carrier comprising: a base suitable for receiving the integrated circuit package such that the leads are supported on surfaces thereof with openings through said base at said base surfaces; a cover having surfaces in alignment with said base support surfaces; elastomeric connector material disposed in said openings in said base and extending therethrough; means for maintaining pressure across said cover and base; and a device under test board having circuitry to match the pattern and density of the integrated circuit package lead configuration, so that when the base is aligned on the device under test board the elastomeric connector electrical paths make contact with the circuitry on the device under test board creating a unique electrical circuit to each package lead.
Claim 5
Dependent Claim
38 words
The carrier and test arrangement of claim 2 wherein the width of said connector segments are such relative to the lead density that several conductor segments contact each lead and there are several insulator segments between each lead.
Claim 6
Dependent Claim
182 words
A carrier and test arrangement for an integrated circuit package having protruding leads, said carrier comprising: a rectangular shaped base suitable for receiving the integrated circuit package such that the leads are supported on surfaces thereof with openings through said base at said base surfaces with notches at each of inner corners of said base to mate with corners of the integrated circuit package; clips at each corner of said base comprising vertical members; a cover with latching edges having surfaces in alignment with said base support surfaces; elastomeric connector material disposed in said openings in said base and extending therethrough; means for maintaining pressure across said cover base and by said clips of said base engaging said latching edges of said cover; and a device under test board having circuitry to match the pattern and density of the integrated circuit package lead configuration, so that when the base is aligned on the device under test board the elastomeric connector electrical paths make contact with the circuitry on the device under test board creating a unique electrical circuit to each package lead.
Claim 7
Dependent Claim
182 words
A carrier and test arrangement for an integrated circuit package having protruding leads, said carrier comprising: a rectangular shaped base suitable for receiving the integrated circuit package such that the leads are supported on surfaces thereof with openings through said base at said base surfaces with notches at each of inner corners of said base to mate with corners of the integrated circuit package; clips at each corner of said base comprising vertical members; a cover with latching edges having surfaces in alignment with said base support surfaces; elastomeric connector material disposed in said openings in said base and extending therethrough; means for maintaining pressure across said cover base and by said clips of said base engaging said latching edges of said cover; and a device under test board having circuitry to match the pattern and density of the integrated circuit package lead configuration, so that when the base is aligned on the device under test board the elastomeric connector electrical paths make contact with the circuitry on the device under test board creating a unique electrical circuit to each package lead.
Claim 8
Dependent Claim
25 words
