  • Apparatus and method for cleaning piezoelectric crystal components
    Patent number: 5167079
    Abstract: An apparatus and method for treating components used in the manufacture of piezoelectric crystals having a very stable oscillating frequency includes an oven with infrared heating lamps and a tray with a removable glass cover. The tray is fitted in the oven so radiant energy from the lamp heats the components in the tray. Nitrogen is continuously flowed through the interior of the tray during the heating to remove oxygen and water vapor together with contaminants driven from the components during heating.
