Ceramic Materials Used In Electronics

The insulating properties of ceramics are well known and these properties have found application in advanced ceramic materials for substrates and packages.

Ceramic materials used in electronics.

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. Clay bricks tiles glass and cement are probably the best known examples. In electronic and electrical industries advanced ceramic materials like barium titanate batio3 piezoelectric materials and semiconductor materials are heavily used for producing ceramic capacitors vibratos temperature sensors oscillators etc.

Ceramics are more than pottery and dishes. Ceramic insulators like alumina are also very good heat conductors. The materials and products are described in this article. 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.

These companies make most consumer products pcbs and virtually anything with. Among the ceramics employed as electronic substrates and packages the dominant material is alumina aluminum oxide al. Engineered ceramics exhibit superior dielectric attributes when compared to other materials like plastics or metals. Abdullahi in reference module in materials science and materials engineering 2016.

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 nearly 4 5 trillion global electronics industry would not exist without ceramics. Ceramic materials are used in a wide range of applications from power distribution to smartphones. 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.

For example ceramic heat sinks provide the right climate for high power electronics. Advanced ceramics in electronics ceramic substrates circuit carriers core materials and many other components are in use throughout the electronics industry. Ceramics used for this type of applications are called functional ceramics. 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.
