Abstract
A method and apparatus is disclosed to allow the frequency adjustment of a crystal resonator sealed in a housing. The housing includes a transparent area which has plating material deposited thereon. The plating material is vaporized by a laser beam which sprays onto the crystal resonator thereby adjusting the operating frequency. The laser beam is scanned over the transparent area until an effective amount of plating material has been vaporized to adjust the frequency of the crystal resonator.
