Metallized Aluminum Nitride (AlN) Ceramics

An important issue in developing highly reliable, fast, high-power devices with modern technology is heat dissipation, as heat reduces reliability and shortens the life of electronic devices. Thermal conductive materials can help solve this problem. Possible thermal conductive materials include beryllium oxide, silicon carbide, aluminum nitride, and boron nitride. However, beryllium oxide is toxic, silicon carbide is a semiconductor with poor dielectric properties, and boron nitride requires complex processing methods to manufacture items. Only aluminum nitride has the best set of properties, is non-toxic, and can be used to create items in simple and effective ways. Metallization Aluminum nitride (AlN) is the most ideal heat dissipation and packaging material among semiconductor electronic materials. Due to its high thermal conductivity, high insulation resistance coefficient, excellent mechanical strength, and thermal shock resistance, it has also become one of the important precision ceramic materials.

The main metallization of aluminum nitride ceramics includes thick film metallization, thin film metallization, electroless plating metallization, and laser metallization.
