XTL sintyron aluminum nitride substrate led aluminium nitride ceramic chip

Brief introduction

Liling Xingtailong Special Ceramics use their own research and development of high quality aluminum nitride

powder as raw material, using casting method to produce aluminum nitride substrate.
This wafer type product can be metallized to make a part of a high thermal conductivity circuit board,

or can be directly used as an insulation sheet after laser cutting.

Class

Liling Xingtailong special ceramics provide different surface treatment options to meet the diversified needs of customers
instant burning substrate: the flatness and roughness of the substrate after sintering can meet the technical requirements,

and there is no need to do special treatment.
Abrasive substrate: The substrate is ground after sintering to achieve a higher level of flatness and roughness.
Polished substrate: The surface of the substrate after sintering is polished to achieve a mirror effect.

Product descritption:

One of the key advantages of using aluminum nitride as a substrate material is its high thermal conductivity.   

With a thermal conductivity of around 170 W/mK, AlN outperforms traditional substrate materials such as 

alumina and silicon carbide, making it an excellent choice for highpower electronic devices that generate a 

significant amount of heat.   This high thermal conductivity allows for efficient heat dissipation, which is 

crucial for the reliability and performance of electronic components.

Properties

1. High Thermal Conductivity:

   AlN ceramic sheets have a thermal conductivity of 170-200 W/m·K, making them ideal for heat dissipation in high-power applications.

2. Low Thermal Expansion:

   The thermal expansion coefficient of AlN (~4.5×10⁻⁶/K) is close to that of silicon (Si) and gallium arsenide (GaAs), reducing thermal stress in electronic assemblies.

3. Excellent Electrical Insulation:

   AlN is an electrical insulator with high dielectric strength, suitable for high-frequency and high-power electronic devices.

4. Mechanical Strength:

   AlN ceramic sheets exhibit high hardness, wear resistance, and mechanical durability.

5. Chemical Stability:

   AlN is chemically stable and resistant to most corrosive environments, making it suitable for harsh operating conditions.

Advantages of aluminum nitride ceramic parts

Aluminum nitride ceramic parts have high thermal conductivity and electrical insulation, so they can be used in a variety of electronic devices.

The thermal conductivity of aluminum nitride is 170W/(mk), which is 5-8 times that of alumina ceramics. Therefore, AlN ceramics have good thermal shock resistance and can be used in a high temperature environment of 2200 ° C.

Aluminum nitride ceramics is one of advanced precision ceramic materials, which is widely used in electronics industry because of its excellent thermal conductivity and electrical insulation properties. For example:

1. Power Electronics:

   Used as substrates for power modules, IGBTs (Insulated Gate Bipolar Transistors), and RF/microwave devices due to their excellent thermal management capabilities.

2. LED Lighting:

   Serve as heat sinks for high-power LEDs, improving thermal performance and extending LED lifespan.

3. Semiconductor Packaging:

   Used in semiconductor device packaging, especially where high thermal conductivity and low thermal expansion are required.

4. Laser Diodes and Optoelectronics:

   AlN ceramic sheets are used as substrates for laser diodes and optoelectronic devices due to their thermal and optical properties.

5. High-Temperature Applications:

   Suitable for use in high-temperature environments, such as sensors, heaters, and protective coatings.
