Silicon nitride ceramic is a high-performance ceramic material, which is made of silicon nitride (Si3N4) powder through molding, sintering and other processes. It has excellent mechanical properties, high temperature stability and corrosion resistance, but also has good electrical and thermal conductivity.
Silicon nitride ceramic substrate is a commonly used ceramic substrate material with the following characteristics and advantages:
High thermal conductivity: The thermal conductivity of silicon nitride is higher than that of aluminum oxide, which can quickly transfer heat and ensure the stability and reliability of the equipment.
Excellent insulation performance: Silicon nitride has high electrical insulation performance, which can effectively isolate interference signals between circuits and improve the reliability and performance of circuits.
Good corrosion resistance: silicon nitride is not easily corroded by chemical substances such as acid and alkali, which ensures the long-term stability and reliability of the substrate.
High mechanical strength: Silicon nitride material has high hardness, excellent pressure resistance and impact resistance, which can meet the requirements of different application scenarios.
Excellent high-temperature performance: Silicon nitride can maintain stable performance at high temperature and is suitable for applications in high-temperature environments.
Good processing performance: Silicon nitride material has high hardness, but excellent processing performance, and is easy to cut, punch and polish.
Safety and environmental protection: silicon nitride material is non-toxic, tasteless, non-flammable, and meets environmental protection standards.
The main advantages of silicon nitride ceramic substrates are excellent performance in high temperature, high frequency and high power, and also have good mechanical strength and chemical stability. They are used in a wide range of fields, mainly including power electronics, LEDs, sensors, microwave and radio frequency equipment, etc.
