Abstract
Abstract @ A method of making a diamond heatsink comprises securing a number of spaced diamonds to a sacrificial plate and then metallising them with, for example, a thin layer of gold, silver, copper or aluminium. The plate and the diamonds are subsequently metal plated with a similar metal to the metallisation until the diamonds are completely covered. The sacrificial plate is removed and the exposed surface cleaned and polished. Finally the assembly is diced to produce a number of individual heatsink assemblies.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
85 words
A method of making a diamond heatsink assembly comprising the steps-of securing a plurality of diamonds to a sacrificial plate, metallising the exposed portions of the diamonds with a relatively thin layer of metal, metal plating the sacrificial plate and the exposed portions of the diamond with a relatively thick layer of metal, removing the sacrificial plate and dividing the layer of metal plating into a plurality of parts, each part including at least one diamond to produce a plurality of individual diamond heatsink assemblies.
Claim 2
Independent Claim
85 words
A method of making a diamond heatsink assembly comprising the steps-of securing a plurality of diamonds to a sacrificial plate, metallising the exposed portions of the diamonds with a relatively thin layer of metal, metal plating the sacrificial plate and the exposed portions of the diamond with a relatively thick layer of metal, removing the sacrificial plate and dividing the layer of metal plating into a plurality of parts, each part including at least one diamond to produce a plurality of individual diamond heatsink assemblies.
Claim 3
Dependent Claim
17 words
A method as claimed in claim 1 in which the sacrificial plate comprises any relatively cheap metal.
Claim 4
Dependent Claim
41 words
3 . A method as claimed in claim 1 or claim 2 in which the relatively thin layer of metallisation on the exposed portions of the diamonds comprises a metal selected from the group comprising gold, silver, copper, aluminium and chromium.
Claim 5
Independent Claim
31 words
A method as claimed in any preceding claim in which the relatively thick layer of metal plating comprises a metal selected from the group comprising platinum, gold, silver, copper and aluminium.
