Thermal Properties

1. High Thermal Conductivity:

Ceramic PCBs offer high thermal conductivity, typically in the range of 20-200 W/m·K, depending on the specific ceramic material used. This high thermal conductivity ensures efficient heat transfer away from heat-generating components, maintaining the PCB's temperature within safe limits.

2. Low Coefficient of Thermal Expansion (CTE):

Ceramic substrates have a low coefficient of thermal expansion, usually around 5-8 ppm/°C. This low CTE minimizes the risk of thermal stress and mechanical failure due to temperature changes, ensuring dimensional stability and reliable performance.

3. Excellent Heat Dissipation:

The thick film base on a ceramic substrate enhances heat dissipation capabilities. This is especially beneficial for high-power applications where effective heat management is crucial to prevent overheating and maintain component reliability.

4. High Thermal Stability:

Ceramic PCBs maintain their properties over a wide temperature range, typically from -55°C to +150°C or higher. This thermal stability ensures consistent performance in both low and high-temperature environments, making them suitable for a wide range of applications.

5. Thermal Shock Resistance:

Ceramic materials are resistant to thermal shock, meaning they can withstand rapid temperature changes without cracking or delaminating. This resistance is essential for applications that experience frequent temperature cycling or sudden temperature shifts.

6. Enhanced Heat Spreading:

The ceramic core substrate provides effective heat spreading across the PCB, distributing heat evenly and preventing localized hotspots. This uniform heat distribution improves overall thermal management and enhances the longevity of the PCB.

7. Integration with Thermal Interface Materials (TIMs):

Ceramic PCBs can be effectively integrated with thermal interface materials, such as thermal pads or thermal paste, to further enhance heat transfer from components to heatsinks or other cooling solutions.

By leveraging these advanced thermal properties, ceramic PCB core substrates with thick film base technology provide exceptional heat management, ensuring reliable and efficient performance in demanding electronic applications.
