摘要： A tuning fork quartz crystal resonator has a base and two resonating arms extended in parallel from the same side of the base. Each resonating arm has asymmetric grooves on its upper and bottom surface, and the via-hole to reliably connect the top and bottom electrode. The asymmetric groove design can simplify the manufacturing process and lower the manufacturing cost. The base has continuous concave on both side surfaces and a recess on the main surface. The energy of ultrasonic wave propagating via the base mounting pads into the ceramic package can be reduced. This unique tuning fork quartz crystal resonator can prevent dramatic reduction of the Q value, and retain the outstanding quality of the resonator.
