Osprey CE 9 (60Si/40Al)

  • Lower cost alternative to Cu/W or Cu/Mo.
  • Close CTE matching ( 9.0  ppm/°C at room temperature) to GaAs die and alumina or LTCC substrates.
  • Thermally stable and stiff, with 6 times the thermal conductivity of Kovar. 
  • One sixth, one quarter and one third the weight of Cu/W, Cu/Mo or Kovar respectively.
  • Machinable and plateable. Improved machinability vs. CE7.
  • Typical applications include RF and microwave packages, electro-optical housings, base plates for power devices and carrier plates for high frequency circuits.
