95%~99.99% Alumina ceramic sheets High purity alumina zirconia insulation ceramic sheets High temperature resistant ceramic substrates
Ceramic sheet/substrate is a special process board made by directly bonding copper foil to the surface (single or double sides) of ceramic substrates such as alumina (Al₂O₃) or aluminum nitride (AlN), silicon carbide (SiC) and silicon nitride (Si3N4) at high temperature. This ultra-thin composite substrate has many superior properties. The following is a detailed introduction to ceramic substrates:
1. Performance advantages of ceramic substrates
Excellent electrical insulation performance: Ceramic substrates have high insulation properties and can ensure electrical isolation between electronic components.
High thermal conductivity: Ceramic materials such as alumina and aluminum nitride have high thermal conductivity, which helps to quickly dissipate heat from electronic components.
Excellent soft solderability and high adhesion strength: The copper foil has a strong bond with the ceramic substrate and can withstand large mechanical and thermal stresses.
Strong mechanical stress and stable shape: Ceramic substrates have high hardness and bending strength and are not easy to deform.
Good thermal cycling performance: The number of cycles can reach 50,000 times, with high reliability.
Wide operating temperature range: generally between -55℃~850℃, suitable for various harsh environments.
Thermal expansion coefficient is close to that of silicon chips: helps to simplify the production process of power modules and improve product reliability.
2. Types of ceramic substrates
There are many types of ceramic substrates, mainly including alumina substrates, aluminum nitride substrates, silicon carbide substrates, silicon nitride substrates, etc. Among them, alumina substrates have become the most commonly used substrate materials in the electronics industry due to their superior mechanical, thermal and electrical properties, as well as abundant raw material sources and relatively low manufacturing costs.
3. Manufacturing process of ceramic substrates
The manufacturing of ceramic substrates requires multiple processes, including cutting, grinding, polishing, laser drilling, etc. These process steps have an important impact on the quality and performance of the final product. For example, laser drilling technology can drill high-precision small holes on ceramic substrates for installing electronic components and connecting circuits.
4. Application fields of ceramic substrates
Ceramic substrates are widely used in many industries due to their unique combination of properties, mainly including:
PCB: used as the base material of PCB, providing excellent thermal management and electrical insulation properties.
Semiconductor packaging: Provides a thermally conductive and electrically insulating platform for integrated circuits.
Automotive components: Used in components such as engine control modules in automotive electronics to help dissipate heat generated by electronic components.
LED substrates: Serves as the basis for light-emitting diode (LED) chips, improving the performance and life of LEDs.
Power modules: Used in power electronics modules such as inverters and converters to help dissipate heat effectively.
Radar systems: Used in radar systems and other electronic components in aerospace and defense applications because they can withstand high temperatures and harsh environmental conditions.
Implantable medical devices: Used in some medical devices and implants because of their biocompatibility and corrosion resistance.
Solar cells: Can be used as substrates for thin-film solar cells, providing durability and resistance to environmental factors.
