Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A circuit board assembly CHARACTERIZED BY: first and second circuit board substrates each CHARACTERIZED BY one or more exterior-mounted chip modules each chip having connections to symmetrically located discrete pad clusters disposed on the interior side of said substrates; and cross-over connections between the corresponding said pad clusters, CHARACTERIZED BY: a two-sided frame for receiving on opposite sides thereof said respective substrates; cross-over cell cavities through said frame and aligned with said corresponding pad clusters; and an elastomeric one-directional conductive material slug disposed in each said cell cavity, the volume of each slug when compressed approximating the volume of said cell cavity.
Claim 2
Dependent Claim
71 words
Apparatus in accordance with claim 1, wherein said substrates further comprise two or more alignment holes at the substrate corners, and wherein said frame further comprises alignment pins for engaging said alignment holes, thereby to assure that said cross-over cell pad arrays appearing on the top surface of said first substrate and the corresponding cross-over cell pad arrays on the bottom surface of said second substrate are in close vertical register.
Claim 3
Dependent Claim
41 words
Apparatus in accordance with claim 2, wherein each said slug comprises a plurality of vertical conductive paths the ends thereof terminating at the exterior opposite vertical surfaces of each slug to make electrical contact with the pads of said pad clusters.
Claim 4
Dependent Claim
32 words
Apparatus in accordance with claim 3, wherein the cross-section of the vertically conductive paths of said slugs is substantially less than the lateral spacing between adjacent contact pads of said pad arrays.
Claim 5
Dependent Claim
17 words
Apparatus in accordance with claim 4, wherein said slug-receiving cavities are formed from hollow open-ended square blocks.
Claim 6
Dependent Claim
21 words
Apparatus in accordance with claim 5, further CHARACTERIZED BY bonding means to adhere said frame to said first and second substrates.
Claim 7
Dependent Claim
33 words
Apparatus in accordance with claim 6, wherein said elastomeric slugs are compressed to a degree which places the resulting slug conductivity within substantially the maximum conductivity range of which the material is capable.
Claim 8
Dependent Claim
29 words
Apparatus in accordance with claim 7, wherein the interior of said frame is hollow, said apparatus further CHARACTERIZED BY means for flowing coolant into and out of said interior.
Claim 9
Dependent Claim
22 words
Apparatus in accordance with claim 8, wherein the volume of each slug when compressed substantially equals the volume of said slug-receiving cavity.
Claim 10
Dependent Claim
67 words
Apparatus in accordance with claims 1, 2, 3, 4, 5, 6, 7, 8, and 9, further CHARACTERIZED BY enclosure means for housing one or more said assemblies, said means CHARACTERIZED BY a backplane including a pin array, dual rail means slidably mounting individual said assemblies and female gang connectors connecting said assembly to said pin array when said assembly is positioned on said slides onto said backplane.
