Ceramic Substrates And Packages For Electronic Applications

Over 150 us companies produce or supply electronic ceramics.

Ceramic substrates and packages for electronic applications.

The materials and products are described in this article. At the same time the vacuum tight housings and substrates must. Printed resistors and high current capacity trough conductive line structures are also available. Rubalit 708 s with 96 al 2 o 3.

The insulating properties of ceramics are well known and these properties have found application in advanced ceramic materials for substrates and packages. The outstanding surface quality on both sides makes it the perfect companion for any commercial thick film paste and even makes it suitable for a number of thin film applications sputtering. Htcc high temperature co fired ceramics alumina system and ltcc low temperature co fired ceramics glass ceramic system are available. Substrates made from rubalit alumina ceramics.

Direct bonded copper dbc substrates are commonly used in power modules because of their very good thermal conductivity they are composed of a ceramic tile commonly alumina with a sheet of copper bonded to one or both sides by a high temperature oxidation process the copper and substrate are heated to a carefully controlled temperature in an atmosphere of nitrogen containing about 30 ppm. Hermetic microelectronic packages also often referred to as hybrid packages multi chip module housings or ic packages are used to package and thereby protect sensitive electronic components and complete electrical assemblies from harsh environmental conditions including high temperature shock and vibration resistance. The most economically important types of electronic ceramics include substrates integrated circuit ic packages and multichip modules capacitors ferrites insulators piezoelectrics and superconductors world electronics development 1998.
