The description of the silicon nitride ceramic substrate

The High-strength and high-thermal-conductivity silicon nitride ceramic substrate, its bending strength is 2-3 times that of aluminum nitride ceramic substrate, which can improve the strength and impact resistance of silicon nitride ceramic copper clad laminates, and weld thicker oxygen-free copper without producing The phenomenon of ceramic cracking improves the reliability of the substrate; by covering with a thick copper substrate, its thermal conductivity is 3-4 times that of the Alumina Ceramic Substrate, which greatly improves the heat dissipation performance of the substrate; the substrate has a stronger current carrying capacity and the overall substrate The heat dissipation performance is better, the thermal resistance is lower, and the temperature shock resistance is stronger.

Application Scope Silicon nitride ceramic substrate has the characteristics of high strength, high thermal conductivity, and high reliability. It can be used to make circuits on the surface by wet etching process. After surface plating, it is a kind of high reliability electronic substrate module packaging Substrate material is the preferred substrate material for 1681 power control modules for new electric vehicles. In addition, the ceramic substrate industry also involves technology in many fields such as LED, fine ceramic preparation, thin film metallization, yellow light lithography, laser forming, electrochemical plating, optical simulation, microelectronic welding, etc. The products include power transmitters, photovoltaic devices, and IGBT modules. , Power-type thyristors, resonator bases, semiconductor packaging substrates and other high-power optoelectronics and semiconductor devices have a wide range of uses.
