Abstract
Abstract A diamond heatsink assembly includes a multifaceted diamond mounted on a metal heatsink. The diamond may be partially embedded in the metal heatsink by pressing, soldering or clamping or the metal heatsink may comprise a split collet arrangement so that the diamond is removable. An electronic component such as a multimetric or a micrometric wave device can be mounted on one or several facets, and a faulty component can be removed and a new one secured to the same or another facet.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A diamond heatsink assembly comprising: a heatsink mounting, a multi-faceted diamond in thermal contact with the heatsink mounting, at least a number of the facets of the diamond being inclined to the surface of the mounting and being prepared and flat for each to support an electronic device, at least a portion of said multi-faceted diamond having a metallic layer, at least one electronic device being supported on the surface of one of the inclined facets of the diamond and connected to the metallic layer on the diamond, and said metallic layer including at least one discontinuity providing a dc break between at least one metallized facet of the diamond and said heatsink mounting and said at least one electronic device.
Claim 2
Dependent Claim
121 words
A diamond heatsink assembly comprising: a heatsink mounting, a multi-faceted diamond in thermal contact with the heatsink mounting, at least a number of the facets of the diamond being inclined to the surface of the mounting and being prepared and flat for each to support an electronic device, at least a portion of said multi-faceted diamond having a metallic layer, at least one electronic device being supported on the surface of one of the inclined facets of the diamond and connected to the metallic layer on the diamond, and said metallic layer including at least one discontinuity providing a dc break between at least one metallized facet of the diamond and said heatsink mounting and said at least one electronic device.
Claim 3
Dependent Claim
21 words
A diamond heatsink assembly as claimed in claim 1 in which the diamond is partially embedded in a metal heatsink mounting.
Claim 4
Dependent Claim
20 words
A diamond heatsink assembly as claimed in claim 1 in which the diamond is soldered to a metal heatsink mounting.
Claim 5
Dependent Claim
20 words
