Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
A mounting arrangement for integrated circuits which include a substrate having a cooling pin protruding from one surface thereof, comprising a printed circuit board having a plurality of holes therein at predetermined positions, said integrated circuits being mounted on said circuit board with the cooling pins thereof protruding through said holes, a plurality of metal studs affixed on the surface of said circuit board opposite the side on which said integrated circuits are mounted and electrically connected to at least one of said protruding cooling pins, and a conductive plate removably fastened to the free extremities of said metal studs.
Claim 2
Dependent Claim
100 words
A mounting arrangement for integrated circuits which include a substrate having a cooling pin protruding from one surface thereof, comprising a printed circuit board having a plurality of holes therein at predetermined positions, said integrated circuits being mounted on said circuit board with the cooling pins thereof protruding through said holes, a plurality of metal studs affixed on the surface of said circuit board opposite the side on which said integrated circuits are mounted and electrically connected to at least one of said protruding cooling pins, and a conductive plate removably fastened to the free extremities of said metal studs.
Claim 3
Dependent Claim
38 words
A mounting arrangement as defined in claim 1 wherein said cooling pins also serve as means for connecting direct current power to said integrated circuits and further including a direct current power source connected to said conductive plate.
Claim 4
Dependent Claim
21 words
A mounting arrangement as defined in claim 2 wherein said conductive plate is secured to said metal studs by threaded connection.
Claim 5
Dependent Claim
29 words
A mounting arrangement as defined in claim 1 wherein said metal studs are soldered to said board, the solder connection forming a connecting neck surrounding at least one pin.
Claim 6
Dependent Claim
38 words
A mounting arrangement as defined in claim 4 wherein said cooling pins also serve as means for connecting direct current power to said integrated circuits and further including a direct current power source connected to said conductive plate.
Claim 7
Dependent Claim
36 words
A mounting arrangement as defined in claim 5 wherein said metal studs each have threaded holes in the ends thereof and said conductive plate is fastened to said studs by screws engaging in said threaded holes.
