Abstract

Abstract An environmentally sealed chip carrier housing for mounting on a printed circuit board. The housing is formed of a dielectric material and comprises a base and an upstanding circular side wall, one surface of which is threadably configured for receipt of a cover member. The base is further provided with plural slots for receiving a like plurality of elongated elastomeric compressive type connectors, and support means for receiving a chip carrier thereon. A cover member is provided for threadably engaging the housing. The cover member is characterized by a top having a peripheral wall thereabout, where the top has a uniformly convex configuration such that the center portion is thicker than the outer portions thereof. By this arrangement, when the cover member is positioned over the housing containing a chip carrier to threadably engage the cover member with said housing, a uniform pressure is applied to said chip carrier, which in turn will exert a uniform pressure against the elastomeric compressive type connectors. Further, the chip carrier is environmentally sealed.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 162 words
An environmentally sealed chip carrier housing for mounting on a printed circuit board, comprising: a. a chip carrier housing formed of a dielectric material and comprising a base and an upstanding circular side wall, one surface of which is threadably configured for receipt of a cover member, said base being provided with plural slots for receiving a like plurality of elongated elastomeric compressive type connectors and shoulder means for supporting a chip carrier thereon, and b. a cover member for threadably engaging said housing, said cover member being defined by a top with a peripheral wall thereabout, where said top has a uniformly convex configuration such that the center portion is thicker than the outer portions thereof, whereby when said cover member is positioned over said housing containing a chip carrier, threadably engaging said cover member with said housing will provide a unifore pressure to said chip carrier which in turn will exert a uniform pressure against said elastomeric compressive type connectors.
Claim 2
Dependent Claim 162 words
An environmentally sealed chip carrier housing for mounting on a printed circuit board, comprising: a. a chip carrier housing formed of a dielectric material and comprising a base and an upstanding circular side wall, one surface of which is threadably configured for receipt of a cover member, said base being provided with plural slots for receiving a like plurality of elongated elastomeric compressive type connectors and shoulder means for supporting a chip carrier thereon, and b. a cover member for threadably engaging said housing, said cover member being defined by a top with a peripheral wall thereabout, where said top has a uniformly convex configuration such that the center portion is thicker than the outer portions thereof, whereby when said cover member is positioned over said housing containing a chip carrier, threadably engaging said cover member with said housing will provide a unifore pressure to said chip carrier which in turn will exert a uniform pressure against said elastomeric compressive type connectors.
Claim 3
Dependent Claim 23 words
The sealed chip carrier housing according to claim 1 wherein the outer surface of the circular side wall of said housing is threaded.
Claim 4
Dependent Claim 23 words
The sealed chip carrier housing according to claim 1, wherein the inside surface of the circular side wall of said housing is threaded.
Claim 5
Dependent Claim 32 words
The sealed chip carrier housing according to claim 1, wherein the vertical dimersion of said elongated elastomeric compressive type connectors is from 5 to 20% greater than the depth of said slots.
Claim 6
Dependent Claim 20 words
The sealed chip carrier housing according to claim 1, wherein said housing is provided with means for receiving a substrate.
Claim 7
Dependent Claim 19 words
The sealed chip carrier housing according to claim 1, wherein said cover is fabricated from a heat conductive material.
