Product Description

Product Description

China Professional Manufacturer of Alumina Ceramic Substrate for Microelectronics Ceramic Base

Alumina ceramic substrate is a type of ceramic material commonly used in electronics, particularly in the manufacturing of integrated circuits (ICs), semiconductors, and other electronic components. Alumina ceramic, also known as aluminum oxide (Al2O3), offers several desirable properties that make it suitable for these applications

·High thermal conductivity
·Electrical insulation
·Chemical inertness
·Mechanical strength
·Dimensional stability

These properties make alumina ceramic substrates widely used in the fabrication of electronic circuit boards, especially in high-power and high-frequency applications where thermal management is critical. Additionally, alumina substrates are often used as a base material for mounting and packaging electronic components due to their excellent thermal and electrical properties.
