Ceramic substrate

Ceramic substrates have advantages such as high thermal conductivity, good insulation properties, high mechanical strength, and good chemical stability. Aluminum nitride ceramic substrates: thermal conductivity > 200 W/m·K, thermal expansion coefficient matches that of silicon. They are widely used in optical communication, high-power LEDs, IGBTs, semiconductor coolers, heaters, aerospace, and military electronic components. Alumina ceramic substrates: used in electric power electronics, automotive industry, chemical industry, and solar cell components, among others.
