    High Uniformity Square Alumina Substrate with Holes / Multi Holes Alumina Sheet

     

     

    Our Alumina substrate has well-balanced properties of insulation, thermal conductivity and breaking strength. Moreover, one of the unique properties is its surface roughness. We can provide the Alumina substrate 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 Substrate: 

    LED packages,  Alumina Substrate 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.)

     

    This Alumina Substrates  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, Alumina Substrates is designed especially to meet the highest demands in thin-film technology.

     

    Alumina  Substrates 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

     

     

    Alumina substrate Specifications
     
    1. material :  Alumina ceramic 
    2. Very small and very large size can be made
    3. High temperature, good abrasive.

    Refractory alumina ceramic substrate/ceramic plate is our main product.Misson can supply high quality alumina plates with competitive prices.

    Very small and very large sized plates can be made.

    Fine grinding can made tight tolerance.

    High temperature and abrasive resistance is good

     

     

     

    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.
