CVD diamond wafers

Applications

The developing trend of electronic consumer products must be getting compact size. Due to this trend, the circuit components must be designed for high density. Therefore, the heat issue will be a problem to electronic components. Electronic components will be malfunction or damage when the temperature is too high or with rapidly excessive heat. Using Alumina to have heat dissipation can’t increase the power of devices. Using copper to have heat dissipation will absorb too much waste heat to endothermic reaction.

Now, electronic and optoelectronic components power is increased to close the limitation of existing cooling package technology. In order to have power upgrade again in the future, we must solve the heat problem first, so how to choose good heat dissipation material is the key for the IC industry. Today, FongsoTech’s CVD diamond wafer is the ultimate heat spreading material can break through the current heat problems and bottle necks. Trust it will become the mainstream of future cooling materials. There are many applications can be applied to other high-tech industries.
