certain materials, such as diamond, provide substantially higher heat spreading capabilities compared with others. however, issues that include cost, availability and application make most of these materials unsuitable for conventional electronic cooling needs.
one substance with excellent heat spreading properties is carbon. improvements in carbon materials are increasing industry interest as cooling needs mount for components and pcbs. carbon-based heat sink materials have included graphite strands, carbon nano-fibers and metal-graphite matrices.
