Beryllium Oxide Ceramic Heat Sinks Applications
Beryllium oxide ceramic is the ideal material used in many high-performance semiconductor parts for applications such as radio equipment. Beryllium oxide ceramic heat sinks can insulate electronic devices electrically, and at the same time remove substantial quantities of heat from them to a chassis heat sink. Beryllium oxide ceramic is used as a filler in some thermal interface materials such as thermal grease. Some power semiconductor devices have used beryllium oxide ceramic between the silicon chip and the metal mounting base of the package in order to achieve a lower value of thermal resistance than for a similar construction made with alumina. It is also used as a structural ceramic for high-performance microwave devices, vacuum tubes, magnetrons, and gas lasers.
