As the requirements for lighter, thinner and more efficient terminal products increase, the development direction of semiconductor solutions is not only to improve performance, heat generation and heat dissipation performance have also become very important factors in semiconductor design. The heat generation is mainly related to the chip manufacturing process and the temperature control algorithm, and the heat dissipation performance can be worked hard on the material and product structure.

Here I want to introduce to you the use of chemical vapor, phase deposition (CVD) diamond, as a new advanced thermal management solution, it is especially suitable for RF power amplifiers. The CVD diamond heat sink has been proven to reduce the overall package thermal resistance, and its performance far exceeds other commonly used materials. How is CVD diamond better than traditional heat dissipation materials?

As a direct relative of diamonds, diamonds with "carbon element" characteristics are not small, including the highest known thermal conductivity, stiffness and hardness ,and at the same time have high optical transmission characteristics, low expansion coefficient and low density in a large wavelength range. Attributes.  These characteristics make diamond a material for thermal management applications that can significantly reduce thermal resistance.

To synthesize diamonds for thermal management applications, the first step is to select the most appropriate deposition technology.  Microwave-assisted CVD can better control the grain size and grain interface, so as to produce high-quality and reproducible polycrystalline diamond that meets the thermal conductivity level of specific applications. At present, CVD diamond has been commercialized, and there are 1000-2000 W/m.K different grades of thermal conductivity to choose from. CVD diamond also has completely isotropic characteristics, strengthening all directions

Saw-cut diamond is an industrial diamond synthesized by the press. It has the highest purity and strength of completely regular crystal shape, excellent thermal stability, and compactness. And sawn diamond can be used to process synthetic diamond powder with different particle sizes and shapes. Saw diamond is an important raw material for synthesizing diamond powder. In addition, the dust produced by sawing grade diamond is very small and can be recycled many times, which greatly reduces the cost of processing synthetic diamond powder. Therefore, compared with other types of cutting diamonds, it is a more efficient and cost-effective choice.

Application of sawing grit diamonds :

Sawing diamond is suitable for sawing and drilling applications with high power and very high impact, and the obtained products can be widely used in diamond tools, such as grinding bricks, grinding heads, cutting tools, drill bits, resin-based binders, electroplating metal bond grinding wheels and other grinding tools after the sawing diamond is processed into a diamond powder.

How to distinguish the grade of saw-cut diamond :

The sawing grade diamond also has many different grades, which are determined by the size of powder particles. The largest particles are called ' grit diamond ', while the smaller particles are called ' powder diamond '. According to the particle size classification, the saw-grained diamond is classified according to the Mold hardness. Saw-grained diamond with large particle size and high hardness is generally used for sawing stone, while a saw-grained diamond with a small particle size and low hardness is generally used for grinding ceramics, glass, and concrete.

There are many grades of saw-grained diamonds on the market, and prices vary according to grade. In general, the higher the grade of saw diamond, the higher the price. However, the grade of serrated diamonds does not always represent quality. Sometimes, low-grade saw diamonds may have better quality than high-grade diamonds. This depends entirely on the manufacturing process and materials used. It is very important to check the grade and quality before purchasing saw diamonds.

Our Boreas sawing diamond series models are BRD100, BRD200, BRD300, BRD400, BRD600, BRD800, and BRD900. Users familiar with our products can clearly identify the products corresponding to our models, but there are also some users who may have previously used diamond powder products from other companies but want to change a better choice but do not know what types of products are corresponding to our products. In the following, I will list the particle size corresponding data of BRD diamond particles and ZND, HHD, ELEMENT SIX, DI, and other companies.
