Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
A heat sink assembly for an integrated circuit, comprising: a substantially square base plate defining an opening and formed with a plurality of downwardly extending integrated circuit fastening members on three sides thereof, said integrated circuit fastening members and a top portion of the base plate cooperatively defining an integrated circuit receiving slot; a fin plate formed with a downwardly extending protrusion, said downwardly extending protrusion extending through the opening of the base plate and having a substantially square configuration and a size slightly smaller than the opening of the base plate; and means for threadedly connecting the fin plate and the base plate together.
Claim 2
Dependent Claim
105 words
A heat sink assembly for an integrated circuit, comprising: a substantially square base plate defining an opening and formed with a plurality of downwardly extending integrated circuit fastening members on three sides thereof, said integrated circuit fastening members and a top portion of the base plate cooperatively defining an integrated circuit receiving slot; a fin plate formed with a downwardly extending protrusion, said downwardly extending protrusion extending through the opening of the base plate and having a substantially square configuration and a size slightly smaller than the opening of the base plate; and means for threadedly connecting the fin plate and the base plate together.
