Beryllium Oxide Ceramic Substrates Description
Beryllium oxide ceramic substrates are made of high purity beryllium oxide ceramics. Beryllium oxide, or beryllia, is the best ceramic thermal conductor and competes with the most conductive metals, and its electrical isolation is equivalent to that of alumina and the best electrical insulators. Beryllium oxide ceramic substrates are produced by ceramic fabrication techniques, followed by sintering at temperatures above 1500 °C. By applying precision fabricating techniques, close dimensional tolerances and high surface smoothness can be obtained for maximum compatibility with metal components. BeO substrates possess a unique combination of thermal, dielectric, and mechanical properties, and they are highly desirable in electronic applications.
