Ceramic Substrate Wiki

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

Ceramic substrate wiki. Ceramics can take the form of pottery utilitarian vessels sculpture casting cores for bronzes or architectural elements such as tiles pipes and bricks. This application of heat causes irreversible changes in within the clay body rendering the form permanent. 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. 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.

Ceramics are objects made from clay or clay mixed with other materials that are subjected to high heat. Up to the 1950s or so the most important were the traditional clays made into pottery bricks tiles and the like also cements and. The thickness of the ceramic substrate determines the resonant frequency of the device. 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.

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. The insulating properties of ceramics are well known and these properties have found application in advanced ceramic materials for substrates and packages. Substrate biology the natural environment in which an organism lives or the surface or medium on which an organism grows or is attached substrate locomotion the surface over which an organism locomotes substrate marine biology the earthy material that exists in the bottom of a marine habitat like dirt rocks sand or gravel. Mcm c ceramic substrate mcms such as low temperature co fired ceramic ltcc the pcb that interconnects the chiplets is known as an interposer.

The materials and products are described in this article. Typical devices include capacitors inductors resistors transformers and hybrid circuits the technology is also used for robust assembly and packaging of electronic components multi. Substrate may refer to. They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments.
