Ceramic materials used in electronics.

Ceramic based components are indispensable in products such as smartphones computers televisions automotive electronics and medical devices. When the electronics unit is working it generates heat and the alumina backing conducts the. Its specific electrical resistance reaches 10 16 ω cm at room temperature while at 1600 c it still reaches a level of 10 6 ω cm. Nimn 2 o 4 materials are widely used in industry as the basis for the production of ceramic temperature sensors due to its electrical properties characterized by a negative temperature coefficient.

Ceramics used for this type of applications are called functional ceramics. Ceramics are more than pottery and dishes. They can be used as backing material or mounting brackets to which other electrical components are attached for example the electronic systems in a modern car are mounted on alumina. This includes the four types of companies identified in section 1.

Much of the processing and assembly of electronic ceramics are done in areas of the world with very low labor costs. The nearly 4 5 trillion global electronics industry would not exist without ceramics. Al 2 o 3 ceramic with purity up to 99 9 remains one of the most commonly used oxide ceramic electrical insulating materials even today. The insulating properties of ceramics are well known and these properties have found application in advanced ceramic materials for substrates and packages.

Ceramic insulators like alumina are also very good heat conductors. Among the ceramics employed as electronic substrates and packages the dominant material is alumina aluminum oxide al. The materials and products are described in this article. Abdullahi in reference module in materials science and materials engineering 2016.

Ceramic materials are used in a wide range of applications from power distribution to smartphones. Advanced ceramics in electronics ceramic substrates circuit carriers core materials and many other components are in use throughout the electronics industry. Clay bricks tiles glass and cement are probably the best known examples. For example ceramic heat sinks provide the right climate for high power electronics.

Engineered ceramics exhibit superior dielectric attributes when compared to other materials like plastics or metals.
