D330 Aluminum Nitride Ceramic Disc
Alias: Aluminum nitride (AlN) ceramic circular substrate

Description：

Ceramic discs made of aluminum nitride (AlN) material, also known as AlN ceramic circular substrates, can effectively improve the operational efficiency and stability of 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 high-performance computing equipment, power semiconductors and LED lighting equipment.

Features:

Aluminum nitride ceramic discs, also known as AlN ceramic circular substrates, take full advantage of the high thermal conductivity and electrical insulation properties of aluminum nitride (AlN) to provide efficient heat dissipation solutions for electronic devices:

1. High thermal conductivity
Aluminum nitride has a thermal conductivity of up to 170 W/m·K, which is close to the thermal conductivity of some metals, which allows it to quickly absorb and conduct heat from heat sources such as semiconductor devices and dissipate heat into the environment.

2. Excellent electrical insulation
With an electrical breakdown strength of up to 17-19 KV/mm and low dielectric losses, aluminum nitride ceramic parts provide excellent thermal management without compromising their electrical insulation, without degrading insulation properties due to heat build-up as some materials do.

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, reduce the stress caused by the difference in thermal expansion, and avoid damage caused by thermal stress.

4. Good thermal stability
It can be used in aerobic environments up to 1000℃, and has good thermal shock stability (ΔT400℃), and can still maintain good mechanical properties at high temperatures, suitable for operating environments at high temperatures.

5. Chemical stability
It has excellent chemical stability, can resist chemical corrosion such as acid and alkali solutions, corrosive media, etc., and maintains long-term stable service performance.

6. Extremely high mechanical strength
Aluminum nitride ceramics have high hardness and mechanical strength, compared with alumina ceramic materials, aluminum nitride has higher bending strength, can resist mechanical stress, is not easy to deform, is wear-resistant, and is suitable for complex applications. Its flexural strength reaches 466-496MPa, ensuring the stability and durability of ceramic structural parts under high loads.

Applications:

Aluminum nitride ceramic parts play a crucial role in many high-tech sectors, especially in applications requiring efficient heat dissipation:

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 ceramic parts can extend the lifespan of LEDs and maintain light efficiency.

4. Electronic packaging
Aluminum nitride ceramics are also widely used in semiconductor packaging to help reduce heat buildup inside the package and improve overall device performance and reliability.

Aluminum nitride ceramics play a pivotal role in modern electronics manufacturing through their exceptional thermal conductivity and electrical insulation, particularly in high-temperature, high-power applications. These ceramic parts 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 ceramic parts ideal for cooling electronic devices, meeting the growing heat dissipation needs of high-performance electronic devices.
