    High Heat Insulation Porous Ceramic Sheet for Semiconductor Usage


    Porous Ceramic Sheet  has a wide application due to its high temperature resistant  and Thermal shock resistant . Alumina possesses a high melting point, strong hardness, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.Porous Ceramic Sheet are available in different dimensions and thicknesses. Call for custom shapes and sizes.


    Porous Ceramic Sheet with  properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. Mingrui provide  Porous Ceramic Sheet 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 Porous Ceramic Sheet : 

    LED packages,  Porous Ceramic Sheet for chip resistors, HIC substrates for heat dissipation, Power modules, FAX substrates for thermal printer head
    *Various processing is available (thin film metalization, thick film metalization, glaze, etc.)


    ThisPorous Ceramic Sheet is characterized by its extremely high strength and thermal conductivity. The outstanding surface quality on both sides makes it the perfect companion for any commercial thick film paste and even makes it suitable for a number of thin film applications (sputtering).


    With its extremely fine surface quality, Porous Ceramic Sheet is designed especially to meet the highest demands in thin-film technology.


    Porous Ceramic Sheet offers consistently reliable and convincing performance even when subject to high thermal and electrical loads in terms of its:


    Thermocycling capability

    Thermal shock resistance

    Flexural strength

    Surface quality

    Thermal conductivity




    Description of Porous Ceramic Sheet:

    Alumina substrates can withstand high temperature and maintain high strength and hardness. Alumina  plates also have superb performances in electrical insulation, high chemical resistance and low thermal expansion. We have various sizes of semi finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.




    Quality assurance:

    1. High heat resistance : Alumina  ceramic has excellent thermal stability,which means that it is widely used in areas where resistance to high temperatures is essential.
    2. Good wear resistance : Alumina eramic is the material of choice for wear parts.
    3. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and alkaline solutions. Good chemical stability of alumina leads to high corrosion resistance.

    Alumina ceramic is the most mature of the engineering ceramics, offering excellent electrical insulation properties together with high hardness and good wear resistance,but relatively low strength and fracture toughness.Alumina ceramics are generally white but may also be pink or ivory.The color is derived from either the sintering additives or impurities in the raw materials.
