Know More About Ceramic Metallization When Ceramic Perfectly Bond With Metal
Ceramic materials , which have excellent properties such as high hardness, high abrasion resistance and high corrosion resistance, but with poor electrical conductivity and weldability to limit their application. While metallization is a process of coating metal on the surface of ceramics, which can improve the conductivity and weldability of ceramics, thus expanding their range of applications. Ceramic after metallization has high thermal conductivity, insulation, heat resistance, strength and coefficient of thermal expansion that matched with the chip, and gradually developed into the ideal packaging substrate for new generation of integrated circuits, as well as power electronic modules. The common ceramic substrate materials can be metallized include Al2O3, SiC, AlN and Si3N4. 1. Thick Film Metallization Thick film metallization is a metal paste coated on the ceramic surface through the screen-printing method, and then after high temperature drying and heat trea...
