Synthetic Diamond Heat Sink

One of the first applications of synthetic diamond was as a heat sink for sensitive electronic components used in the telecommunications industry.

Synthetic diamond heat sink.

Composite materials such as synthetic diamond aisic dymalloy and copper tungsten pseudoalloy are occasionally used as chip substrates or submounts which double as heat sinks. Synthetic diamond is widely used in abrasives in cutting and polishing tools and in heat sinks. 460 pages report global synthetic diamond market to expand at a cagr of 7 2 during the period between 2019 and 2027 and the market estimates the global synthetic diamond to reach us 34 3 bn by 2027 from us 18 3 bn in 2018. Surprisingly although diamond is an electrical insulator it also has excellent thermal conductivity.

Jan 12 2006 37. Ic diamond 7 carat thermal compound maximizes thermal heat transfer between the cpu core and heat sink by taking advantage of diamond s superior thermal conductivity. Search by specification learn more screens 126 companies screens consist of a surface with openings of specific sizes. Efficient heat dissipation prolongs the lifetime of those electronic devices and the devices high replacement costs justify the use of efficient though relatively expensive diamond heat sinks.

Since then element six has developed a range of polycrystalline diamond and synthetic diamond composite materials that can be used in thermal management applications. Diamond films can be synthesized using chemical vapor deposition cvd. Synthetic diamond heat spreaders prevent silicon and other semiconducting materials from overheating. A synthetic diamond heat sink which can be easily shaped and which ensures a consistently high thermal conductivity in which the diamond is a type ib diamond containing 50 to 100 ppm nitrogen.

Sumicrystal type ib is a synthetic single crystal diamond containing evenly distribute nitrogen in quantities of several tens of ppm. Purified synthetic diamond has a thermal conductivity of 2 000 2 500 w mk compared to 406 429 w mk for pure silver. Electronic applications of synthetic diamond are being developed including high power switches at power stations high frequency field effect transistors and light emitting diodes. This property has promoted diamond thin film applications as a heat sink layer to help cool electronic and photonic devices.
