Quartz crystal resonator

The utility model particularly relates to a quartz crystal resonator. The utility model provides a quartz crystal resonator includes base, wafer, metal kovar ring sum metal attachment, and the wafer is located the base, and metal kovar ring sintering is at the oral area of base, and metal attachment holds in the intra -annular region that metal kovar ring formed and metal attachment places the oral area at the base, it is as an organic whole with metal kovar ring rigid coupling that metal attachment passes through laser seam welding. The utility model discloses a brand -new arrangement structure, be about to metal attachment and hold inside the intra -annular region that metal kovar ring formed to make the clearance between metal attachment and the metal kovar ring can go on within the settlement scope. Compared with the prior art, the utility model discloses all require the machining precision of metal attachment and metal kovar ring and the fit tolerance between the two lower, thereby the utility model disc
