Ceramics are used to produce packages that are used with active and passive electronic components such as chips, resistors, capacitors, sensors and other critical devices. These devices are used in automotive electronics, telecommunications, medical, computers, and a huge variety of electronic instruments and consumer appliances.

Alumina (94% Al2O3)  White or Black Ceramic is the most popular ceramic material for multilayer packages.  It offers high strength, good thermal conductivity, hermeticity, excellent electrical properties and the lowest cost high density interconnect.
