Alumina Ceramic Heat Sink

Alumina ceramic heat sinks, also known as ceramic substrates or chips, are an efficient thermal management solution, particularly suitable for high-performance electronic devices. The key features of these heat sinks include:

High Thermal Conductivity

With a thermal conductivity of up to 27.5 W/(m.K), alumina ceramic can quickly absorb and dissipate heat from electronic components, effectively reducing overheating issues.

Excellent Electrical Insulation

Featuring a high dielectric breakdown strength of over 10 KV/mm and low dielectric loss, ensuring efficient heat conduction while providing electrical insulation.

Mechanical Stability

With a compressive strength of up to 2000 MPa and a Vickers hardness of 15.7 GPa, ensuring durability and stability under physical stress.

Thermal Stability and Thermal Shock Resistance

Capable of withstanding temperatures up to 1650°C with good thermal shock resistance, making it suitable for use in high-temperature environments.

Custom Design

Heat sinks are typically rectangular or square and can be customized in size and thickness to meet specific assembly and performance requirements.

Alumina ceramic heat sinks have widespread applications in the electronics manufacturing industry, including key applications such as:

LED Lighting Systems
