ABSTRACT:
Resonators adapted to be supported from a single support arm are made by a rocess wherein the resonator and its support arm are blanked in a single piece from a flat plate of piezoelectric material. The resonator electrodes are formed on the resonator and conductors formed on the support arm in a single metallization operation. If desired, the support arm may be left attached to the flat plate by a region of reduced cross section after the blanking step. The metallization step may include metallization of a portion of the flat plate to form a circuit over the conductor to the electrodes. The resonator may then be vibrated and tested while its support arm is still attached to the flat plate by applying an electrical potential to the metallized portion of the plate. After testing, the resonator support arm may be broken away from the flat plate at the region of reduced cross section. Several resonators may be made simultaneously by the process from a single flat plate of piezoelectric material.
