AlN Ceramic Disc

AlN Ceramic Disc's thermal conductivity ranges between 170 and 220 W/m.K. This thermal conductivity is significantly higher—5 to 8.5 times greater—than that of traditional alumina ceramics, making AlN Ceramic Discs ideal for applications where efficient heat removal is critical. This makes them particularly valuable in the electronics industry, where the dissipation of heat is paramount to maintaining the performance and longevity of electronic devices.

The coefficient of thermal expansion of AlN Ceramic Discs is similar to that of silicon (Si), which plays a crucial role in ensuring the reliability of silicon chips. This similarity helps minimize thermal stress during temperature fluctuations, thereby enhancing the durability and performance of Si-based electronic components. This property is particularly beneficial in high-precision applications where thermal expansion mismatch can lead to failure or reduced efficiency.

AlN Ceramic Discs are also known for their high insulation resistance and voltage resistance strength. Despite these high insulation properties, they maintain a low dielectric constant and dielectric loss, making them ideal for applications in the electronics field where electrical insulation and efficient signal transmission are required. These properties enable AlN Ceramic Discs to be used in high-frequency communication devices, ensuring optimal performance and minimal energy loss.

The mechanical strength of AlN Ceramic Discs is another key advantage. With a mechanical strength reaching up to 450 MPa, these discs feature a very dense ceramic body that is free of porosity, which enhances their structural integrity and resistance to mechanical stress. This robustness ensures that AlN Ceramic Discs can withstand the rigors of demanding applications without compromising their performance or reliability.

Another compelling feature of AlN Ceramic Discs is their purity, which can reach up to 99%. This high purity level ensures that the material is free from contaminants and meets stringent safety and environmental regulations such as RoHS and REACH. The non-toxic nature of AlN Ceramic Discs makes them suitable for a wide range of applications, including those where material safety is a critical concern.

In the context of semiconductor manufacturing, AlN Ceramic Discs exhibit excellent plasma resistance. During semiconductor processing, volatile precursor gases, plasma, and high temperatures are used to deposit high-quality thin films on wafers. The durability of AlN Ceramic Discs allows them to withstand these harsh environments, making them perfect for use in deposition chambers and wafer handling tools.

AlN Ceramic Discs find diverse applications across various industries. In the field of electronics, they serve as substrates for high-power electronic devices, where their thermal conductivity and electrical insulation properties are critical. They are also used as heat sinks for high-power LEDs, effectively managing heat dissipation to ensure optimal performance and longevity.

In addition to electronics, AlN Ceramic Discs are utilized in high-frequency communication devices due to their favorable thermal and electrical properties. Their application extends to laser systems and microwave components, where their ability to handle high power and maintain signal integrity is indispensable.

Moreover, AlN Ceramic Discs are employed as cutting tools, leveraging their excellent thermal and mechanical properties to withstand the high stress and temperatures involved in cutting operations. Their ability to maintain sharpness and durability under extreme conditions makes them a preferred choice for precision cutting applications.
