AlN ceramic shallow groove plates
Alias: Insulating aluminum nitride (AlN) ceramic heat-preservation substrates
Description：
Shallow groove plates made of aluminum nitride (AlN) ceramics, also known as insulating aluminum nitride ceramic heat-preservation substrates. It can effectively retain heat and continuously conduct heat, thereby improving the operational efficiency and stability of the equipment. This material is mainly used as: insulating substrates for high-power semiconductor devices, heat dissipation substrates for large-scale and ultra-large-scale integrated circuits, separator materials inside lithium batteries, cutting tools, packaging materials and heat dissipation plates, etc., especially suitable for aerospace, high-performance computing equipment, power semiconductors and LED lighting equipment, among which thermal insulation needs are particularly critical.
Features:
Aluminum nitride shallow groove plates, also known as insulating aluminum nitride ceramic heat-preservation substrates, leverage the high thermal conductivity and electrical insulation properties of aluminum nitride (AlN) to provide efficient thermal insulation solutions for electronic devices:
1. High thermal conductivity
The thermal conductivity of aluminum nitride is as high as 170 W/m·K, which allows it to quickly absorb and conduct heat from heat sources (such as semiconductor devices), thereby ensuring the operational efficiency and stability of the equipment.
2. Excellent electrical insulation
With an electrical breakdown strength of up to 17-19 KV/mm and low dielectric losses, aluminum nitride shallow groove plates provide excellent thermal management capabilities without compromising their electrical insulation.
3. Low coefficient of thermal expansion
Its coefficient of thermal expansion is 3.2-3.4×10-6/℃, which is close to silicon, which makes it have excellent compatibility with semiconductor materials when the temperature changes, and reduces the stress caused by the difference in thermal expansion.
4. Good thermal stability
It can be used in aerobic environments up to 1000℃ and has good thermal shock stability (ΔT400℃), making it suitable for operating environments with high temperatures or large temperature changes.
5. Smooth surface and Uniform thickness
This helps improve thermal contact efficiency and reduce thermal resistance, thereby enhancing heat dissipation performance.
Applications:
Aluminum nitride shallow groove plates play a crucial role in many high-tech sectors, especially in applications that require efficient heat dissipation or heat-preservation:
1. High-performance computing equipment
Such as servers and workstations, these devices generate a lot of heat and need to dissipate heat efficiently to maintain stable and efficient operation.
2. Power semiconductors and power electronics
Including drive systems for frequency converters and electric vehicles, the heat generated by power elements in these systems needs to be controlled through efficient thermal management.
3. LED lighting equipment
LED components generate higher heat, and using aluminum nitride substrates can extend the lifespan of LEDs and maintain light efficiency.
4. Electronic packaging
Aluminum nitride substrates are also widely used in semiconductor packaging to help reduce heat buildup inside the package and improve overall device performance and reliability.
Aluminum nitride substrates play a pivotal role in modern electronics manufacturing through their exceptional thermal conductivity and electrical insulation, particularly in high-temperature, high-power applications. These substrates not only effectively improve the operational efficiency and stability of the equipment, but also greatly extend the service life of the equipment through optimized thermal management. Its high performance and reliability make aluminum nitride substrates ideal for cooling electronic devices, meeting the growing heat dissipation needs of high-performance electronic devices.
