Osprey CE 7(70Si/30Al)

  •  Lower cost alternative to Cu/W or Cu/Mo.

  • Very close CTE matching (7.4 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 and Kovar respectively.

  • Machinable and plateable.

  • Typical applications include RF and microwave packages, electro-optical housings, base plates for power devices and carrier plates for high frequency circuits.
