    Pcb Al2O3 Ceramic Substrate Alumina Ceramic Plate Good Polished High Insulation

    alumina substrate,ceramic substrate,alumina ceramic substrate,ceramic pcb substrate


    This alumina substrate with excellent characteristics was made possible thanks to our own thin sheet ceramics manufacturing technology.
    We also handle processed alumina substrates with fine rounded/square holes or slits, as well as polished substrates.


    Main Applications

    • A. High-frequency thin film circuit substrates
    • B. Capacitor/resistor substrates
    • C. Sensor component substrates

    Features

    • A.Low surface roughness
      Even heat treated products have a surface roughness that is equivalent to that of polished products.
      (Ra 0.03μm)
    • B.High bending strength
      It has a three-point bending strength of 660 MPa which is approximately twice that of conventional substrates.
    • C.High purity
      It is made from 99.9% pure alumina.
    • D.Fine material properties
      It is a dense material with few internal pores.
    • E.Good electrical characteristics
      Low dielectric loss tangent in the high frequency band.
      (tanσ:10-4 at10 GHz)
    • Ultra-thin substrates with a thickness of 0.1 mm are also available.
