Sensor technology will help us achieve environmental goals surrounding cleaner energy and lower carbon, including the electrification of vehicles; serving autonomous vehicles and smart city infrastructure. It is used to collect big data required for management, control and safety; widely used Applied to the medical market, etc.The application for sensor is becoming more and more popular.
With the continuous improvement of sensor input power, the size of the sensor continues to shrink, and the large heat generated by the large power dissipation puts forward newer and higher requirements for packaging materials. The application prospect of the base sensor is broad, which also has more rigid requirements on the performance of the packaging material itself.
The advantages of ceramic materials
1. High thermal conductivity, meeting the heat dissipation requirements of the sensor;
2. Good heat resistance, meeting the application requirements of sensors at high temperature (Higher than 200°C);
3. The thermal expansion coefficient is matched to match the thermal expansion coefficient of the chip material for sensor to reduce the thermal stress of the package;
4. The dielectric constant is small, the high frequency characteristic is good, reduce the signal transmission time of the sensor, improve the signal transmission rate;
5. High mechanical strength, meeting the mechanical performance requirements of sensor during device packaging and application;
6. Good corrosion resistance, able to withstand the erosion of strong acids, strong alkalis, boiling water, organic solutions for sensor, etc.;
7. The structure is compact and meets the requirements of hermetic packaging for sensor.
Some data show that for every 2°C increase in the temperature of electronic components, the reliability decreases by 10%. Obviously, the overheating of electronic components is one of the culprits of the shortened equipment life. To do a good job in thermal management of equipment, ceramic copper clad laminates are indispensable. Best ceramic copper clad laminates have high thermal conductivity (thermal conductivity 180 W/(mK) ~ 260 W/(mK)), which can dissipate heat in time. Ensure the stable operation of equipment and effectively extend the life cycle of sensor or other product.
