Copper Diamond Heat Sink

As heat spreaders and heat sink 1 6.

Copper diamond heat sink.

Since its reorganization in 2001 sumitomo electric u s a. Most fundamental necessities in the development of semiconductor devices is the need to dissipate the large amounts of heat that is generated during operation of such devices. Sumitomo electric has successfully developed a variety of heat sink materials with high thermal conductivity and a unique. Applied diamond can build heat spreaders for the most extreme possibilities.

Additive manufacturing am can overcome this issue because of its high. Also the conductivity of diamond doesn t mean that it will release its heat faster than say copper it would be like aluminum and just soak up the heat without doing much to dissipate it. The unsurpassed thermal conductivity of diamond and its high electrical resistivity allow for better performance across virtually. Cvd diamond heat spreaders and cu heat sinks are crucial components for efficient heat dissipation in high power electronics and photonics.

The two components were bonded by a multi layer ag in. A 2000 w m k diamond heat spreader can dissipate 110w heating power hotspot heat flux of 10 2kw cm 2 while maintaining the maximum hotspot temperature. The ideal material working as heat sink and heat spreader should have a low coefficient of thermal expansion cte and a high thermal conductivity. It is known from former experiments that there is a very weak bonding between as received diamonds and pure copper matrix in the consolidated composite.

Diamond in any cooling application would be best used as an interface between the source and the dissipation medium this case the heatsink not. 0 1000 to 0 5000 mm. The ideal material working as heat sink and heat spreader should have a coefficient of thermal expansion cte. As a material diamond has no peer as a semiconductor medium.

Has been a sales and marketing company serving various industries and markets in north america and responsible for new products of sei group companies as well as the following products already in the market. Copper cu diamond d composites have excellent thermal property but are hard to manufacture with conventional methods. Aluminum silicon carbide. Copper diamond composites were produced by the powder metallurgical method.
