data sheet for ceramic substrates

Q：What materials are commonly used for manufacturing ceramic substrates?

A：Ceramic substrates are typically made from materials such as Alumina (Al₂O₃), Aluminum Nitride (AlN), and Silicon Nitride (Si₃N₄). These materials offer excellent thermal conductivity, electrical insulation, and mechanical stability, making them suitable for electronic applications.

Q：What are the typical applications of ceramic substrates?

A：Ceramic substrates are commonly used in electronics for mounting and packaging semiconductor devices, LED modules, power electronics, and microwave circuits. Their excellent thermal and electrical properties make them ideal for these high-performance applications.

Q：How does the thermal conductivity of ceramic substrates compare among different materials?

A：The thermal conductivity of ceramic substrates varies by material. For example, Aluminum Nitride (AlN) offers high thermal conductivity, typically around 170-220 W/m·K, making it superior to Alumina, which has a thermal conductivity of about 20-30 W/m·K. This makes AlN substrates ideal for applications requiring efficient heat dissipation.

Q：Can ceramic substrates be customized for specific applications?

A：Yes, ceramic substrates can be customized in terms of size, thickness, metallization patterns, and hole configurations to meet specific application requirements. Customization ensures that the substrate fits perfectly within the electronic assembly and meets performance standards.

Q：What are the electrical insulation properties of ceramic substrates?

A：Ceramic substrates provide excellent electrical insulation, with high dielectric strength and low dielectric loss. This makes them suitable for use in high-voltage and high-frequency electronic applications, ensuring reliable performance and safety.
