Ceramic Substrate Wiki

A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. Among the ceramics employed as electronic substrates and packages the dominant material is alumina aluminum oxide al. Substrate may refer to. The thickness of the ceramic substrate determines the resonant frequency of the device.

Up to the 1950s or so the most important were the traditional clays made into pottery bricks tiles and the like also cements and. 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. The materials and products are described in this article. This application of heat causes irreversible changes in within the clay body rendering the form permanent.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. Ceramic is the name for some materials that are formed by the use of heat the word ceramic comes from the greek word κεραμικός keramikos chemically it is an inorganic compound of metal non metal or metalloid atoms held together by chemical bonds. Typical devices include capacitors inductors resistors transformers and hybrid circuits the technology is also used for robust assembly and packaging of electronic components multi. This is often either organic pcb used in amd s zen 2 microarchitecture or is made of silicon as in high bandwidth memory 6 both have their advantages and limitations.

The insulating properties of ceramics are well known and these properties have found application in advanced ceramic materials for substrates and packages. Ceramic resonators are made of high stability piezoelectric ceramics generally lead zirconium titanate which functions as a mechanical resonator in operation mechanical vibrations induce an oscillating voltage in the attached electrodes due to the piezoelectricity of the material. Co fired ceramic devices are monolithic ceramic microelectronic devices where the entire ceramic support structure and any conductive resistive and dielectric materials are fired in a kiln at the same time. Ceramics are objects made from clay or clay mixed with other materials that are subjected to high heat.
