    Alumina ceramic substrate has lots of advantages, it has good thermal conductivity, stable insulation, thermal shock resistance, wear resistance, Anti-acid and Anti-alkali etc. Can be used in thick film hybrid integrated circuits HTC, LED ceramic heat sink, power modules, semiconductor devices and other fields. Commonly used ceramic substrates are Al2O3, AlN, SiC, BeO, BN, ZrO2 and glass ceramics. Although the thermal conductivity of Al2O3 ceramic substrate is not high (20W/m.K), it is the most widely used ceramic substrate because of its relatively simple production process, low cost and low price.

     

    Alumina Sheet with  properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. Mingrui provide  Alumina sheet  / Alumina ceramic board which is excellent in adhesion with a thin film and thick film metalization due to fine particles.

    ■Good smoothness / flatness with less porosity. Excellent in adhesion with thin film and thick film materials.
    ■Less variance in outline, plate thickness, slit pitch, etc.
    ■Minimal warpage, bending, and undulation.
    ■Physical and chemical properties are stable even under a hot environment. Excellent in thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.
    ■Superior mechanical strength. Products with higher mechanical strength are also in our lineup.
    ■Excellent resistance against oil and chemical.
    ■Excellent in insulation properties, high dielectric breakdown voltage, high surface resistivity / volume resistivity, and small dielectric constant.
    ■Stable breaking strength, and less variance in shape or dimensions.
    ■The high reflective substrate, especially suitable for optical applications such as LED, is also available.

    Applications of Alumina sheets/  Alumina Ceramic Board : 

    Alumina ceramic is mainly used in large power equipment, IC MOS tube, IGBT chip heat conducting insulation, high frequency power supply, communication, mechanical equipment, strong current, high voltage, high temperature and other thermal heat insulation parts need products.
    Physical properties: high thermal conductivity, high voltage insulation resistance, high temperature resistant, abrasion resistant, high strength.
