Recently, BJWE, a leading single crystal diamond technology provider in China, announced:
The single crystal diamond heat sink product developed by the company is used for heat dissipation in 5G microwave RF power amplifiers, and has completed customer verification testing, achieving large-scale mass production.
The rapid development of electronic and optoelectronic technology has put forward the demand for SWaP (Size, Weight and Power) in radar systems, which is to increase radar power while further reducing system size and weight.
Small volume high-power devices inevitably increase heat generation, and the heating of the chip not only increases energy consumption, but also affects the safe and efficient working state of the chip.
Therefore, there is an urgent need to find a new generation of small-sized and high-efficiency heat dissipation materials and methods.
The BJWE project focuses on researching reliable machining methods that combine high-quality single crystal diamond materials with microchannel heat dissipation structures, preparing single crystal diamond microchannel heat sink substrates for high-power device heat dissipation, and improving heat dissipation efficiency by optimizing heat dissipation methods and structures.
Single crystal diamond microchannel heat sink substrate is not only an ideal heat dissipation material and method for power devices, but also can solve the heat dissipation problem of devices in harsh environments such as high temperature and high corrosion.
