Abstract:
A resonator assembly comprising:(a) a quartz crystal-based resonator plate including a central portion and a border substantially surrounding the central portion, the central portion and border formed by removal of material from a solid quartz crystal plate, wherein the border includes a first region physically separated from the central portion and a second region joined to the central portion, and wherein the resonator plate includes a crystallographic orientation wherein a length of the resonator plate is aligned along the X-crystallographic axis of the quartz crystal material forming the resonator plate; (b) a plurality of terminal electrode areas disposed on the resonator plate; (c) a quartz crystal-based base plate secured to the resonator plate, and including no through holes; (d) a plurality of terminal electrode areas disposed on the base plate, and includes no through holes; and (e) a conductive adhesive disposed between the terminal electrode areas on the base plate and the terminal electrode areas on the resonator plate.
