Hermetic Solutions Group Releases DiaCool Material

Hermetic Solutions Group (HSG) has released DiaCool, a diamond based composite material. With the constant evolution of semiconductor device technology, the materials used, and their respective applications, are driving engineers to deliver more functionality in increasingly smaller spaces. Combined with the need to deliver more power, higher frequencies, etc., these applications require new and enhanced thermal management techniques and technologies.

While the use of new semiconductor materials such as SiC, GaN and even diamond is on the rise, until now, the design engineer has been left with tried and true legacy material technologies that are rapidly reaching the limits of their capabilities. To help engineers improve thermal management efficacy, HSG is releasing a new diamond based metal matrix composite material that provides a highly efficient solution.


These new DiaCool materials from HSG use diamond powders that, when combined with different base metals such as aluminum, copper and silver, provide a superior thermal management solution for nearly any product need. These new materials offer an effective solution for spreading and dissipating the high levels of thermal energy generated by semiconductors utilizing the latest materials.


According to Dave DeWire, HSG's VP of Business Development, "This DiaCool product solution is ideal for high power density applications where the designer needs a thermal material that can effectively operate in demanding applications where dissipating heat from sensitive electronics to maintain robust long term functionality is crucial. The tailored and device-friendly low coefficient of thermal expansion (CTE) of this DiaCool material coupled with thermal conductivity that is 3 to 4x higher than legacy metal matrix materials and alloy's delivers our significant customer benefits when building products that take advantage of new wide bandgap devices that use GaN, SiC or diamond. This new material is another great example of how our customers have come to rely on Hermetic Solutions Group for driving continuous innovation and providing long standing, robust, value added solutions."
