Resonance sheet fixing structure of quartz crystal resonator

Abstract

The invention discloses a resonance sheet fixing structure of a quartz crystal resonator. The resonance sheet fixing structure comprises a dispensing platform and a resonance sheet, wherein one end ofthe resonance sheet is fixed on the dispensing platform through a colloid; the resonance sheet fixing structure of the quartz crystal resonator is characterized in that the colloid comprises a bottomglue point and a surface glue point which are fused together, the bottom glue point is conductive glue, and the surface glue point is non-conductive glue, so that the resonance sheet fixing structureof the quartz crystal resonator has the advantages that the surface glue adopts the non-conductive glue, half of the conductive glue is saved, and the production cost is greatly reduced; in addition,the situation that electric pollution is caused to the upper surface of the resonance sheet by glue points dripped by the conductive glue is avoided; and the short-circuit condition caused by contactbetween the electrode and the metal shell due to over-high conductive adhesive points is avoided.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a resonant plate fixing structure of a quartz crystal resonator. Background technique [0002] Both the quartz crystal resonator and the quartz crystal oscillator include a base and a quartz resonator. The quartz resonator is formed by cleaning and plating electrodes on the quartz wafer. Most of the quartz wafers used to make the resonator in the prior art can be approximately regarded as complete Cuboid structure, in order to fix the quartz resonator in the base of the resonator or resonator and realize the electrical connection between the upper and lower electrodes of the resonator and the electrodes on the dispensing platform, it is necessary to conduct electricity on the dispensing platform in the resonator or oscillator base. Glue, and then place one end of the quartz resonator on the glue point, relying on the adhesive force of the glue point to achieve fixation. In o...

Problems solved by technology

[0004] The main component of conductive adhesive is silver powder, and the cost of silver powder accounts for more than 80% of the cost of conductive adhesive. Both the base glue and the top glue use conductive adhesive, resulting in a waste of cost

[0005] In addition, the technical defect of glue dispensing, when dispensing glue points on the surface, the glue points may splash, and falling on the upper surface of the resonant plate can form electrical pollution on the upper surface of the resonant plate, resulting in increased crystal resistance or even stop vibration

[0006] Furthermore, since the quartz crystal resonator and the quartz crystal oscillator are generally packaged in a metal shell, it is difficult to control the conductive adhesive when it is cured and formed. If the glue is pulled, the glue point will be too high, and it will cause a short circuit caused by contact with the metal shell; If beach glue occurs, the contact resistance will be large
