Abstract

The utility model discloses a quartz crystal resonator which comprises a base and a quartz wafer. A first electrode and a second electrode are arranged on the quartz wafer. The first electrode and the second electrode are connected with the base through lower gel points. An upper gel point bonded with the corresponding lower gel point is arranged on the first electrode. With the fixation of three gel points, on the basis that the product reliability is ensured, the stress resistance of the product is decreased, thus the product is stabilized to test resonance resistance variation under different excitation power.

Description

A kind of quartz-crystal resonator

Technical field

The utility model relates to a kind of resonator, especially a kind of quartz-crystal resonator.

Background technology

With reference to Fig. 1, existing for SMD(Surface Mounted Devices, surface mount device) 4 points of the common employing of quartz-crystal resonator glue mode is quartz wafer fixedly, specific operation process: point out two adhesive dots with accurate syringe needle at pedestal 1 first, be placed on respectively two electrodes of quartz wafer 2 on the glue point, and then carry out secondary point glue at electrode, be two adhesive dots of point equally.But find that in actual applications this series products resonant resistance value when carrying out low-frequency range such as the operation of 12M product is bigger than normal, test resonant resistance variable quantity is larger under different exciting powers.

Summary of the invention

Problem to be solved in the utility model just provides a kind of quartz-crystal resonator, and the stressed resistance with product on the basis that guarantees product reliability reduces, thereby stable prod is tested the resonant resistance variable quantity under different exciting powers.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of quartz-crystal resonator, comprise pedestal and quartz wafer, described quartz wafer is provided with the first electrode and the second electrode, described the first electrode is connected described pedestal with described the second electrode by lower glue point, also be provided with on described the first electrode with corresponding under the gluing point of glue spot gluing.

The beneficial effects of the utility model: the quartz wafer in the utility model quartz-crystal resonator, its first electrode is fixing by upper and lower glue point, and the second electrode is only fixing by lower glue point, i.e. 3 some plastic structures, can guarantee the original stability of quartz crystal, can reduce again the glue point, reduce the glue consumption, save cost, the more important thing is: some glue number reduces, so that the glue contact area of product reduces, thereby reduced the product contact resistance, simultaneously with the stressed resistance of product also corresponding reducing.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the structural representation of existing quartz-crystal resonator;

Fig. 2 is structural representation of the present utility model.

Embodiment

With reference to Fig. 2, the utility model quartz-crystal resonator, comprise pedestal 1 and quartz wafer 2, described quartz wafer 2 is provided with the first electrode 21 and the second electrode 22, described the first electrode 21 is connected described pedestal 1 with described the second electrode 22 by lower glue point 12, also be provided with on described the first electrode 21 with corresponding under glue put 12 bonding gluing points 11.

Specifically: quartz wafer 2 is with two electrodes, conducting resinl is gone up with accurate syringe needle point in the position of corresponding two electrodes on the pedestal 1, form lower glue point 12, the electrode of quartz wafer 2 is positioned on the lower glue point 12, then at the upper surface of the first electrode 21, be conducting resinl on the electrode millet cake, form gluing point 11.Such the first electrode 21 adopts upper and lower 2 glue to fix, guarantee the Stability and dependability of quartz wafer 2, and only having lower surface to pass through lower glue 12, the second electrode 22 is connected with pedestal 1, so that the glue contact area of product reduces, thereby reduced the product contact resistance, simultaneously with the stressed resistance of product also corresponding reducing.

By above-described embodiment, the purpose of this utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top embodiment.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.

Claims

1. quartz-crystal resonator, comprise pedestal and quartz wafer, described quartz wafer is provided with the first electrode and the second electrode, it is characterized in that: described the first electrode is connected described pedestal with described the second electrode by lower glue point, also be provided with on described the first electrode with corresponding under the gluing point of glue spot gluing.
