Abstract
The utility model relates to a chip type quartz crystal resonator comprising a base (1), a metallic upper cover (2), a quartz crystal plate (3) and an electrode (4), wherein a low melting point metallic packaging layer (5) which is fused and sealed through heating is arranged between the metallic upper cover (2) and the base (1), and the metallic upper cover (2) is covered on the base in a melting and sealing mode. The resonator adapts to the requirements of miniaturization and scale development of an electronic element, can realize the technical effect of automatic surface mounting, and is especially suitable for a high precision electric appliance whose occupied space is small, such as a cell phone, a notebook computer and the like.
Description
Technical field
A kind of resonator that the utility model relates to refers in particular to a kind of sheet type quartz crystal resonator.
Background technology
The cap of traditional sheet type quartz crystal resonator and pedestal sealing employing viscose glue are fixed and are sealed, because sheet type quartz crystal resonator volume is small, the thickness of viscose glue is wayward when encapsulation, and be subjected to the restriction of material and processing technology, the impact resistance of the quartz-crystal resonator of this structure, ageing resistace difference and frequency accuracy are not ideal enough, cause the quality problems of product hermeticity difference easily and directly influence use, particularly can't reach and satisfy instructions for use as high accuracy electronic products such as mobile phone, notebook computer, satellite communication devices.Other has the fixed structure of inner crystal wafer inside also to have the shortcoming of impact resistance and ageing resistace difference, therefore, how to address the above problem, and becomes problem demanding prompt solution.
The utility model content
The technical problems to be solved in the utility model provides a kind of good airproof performance, production and processing technology is simple, the strong and good sheet type quartz crystal resonator of ageing resistance of impact resistance.
For solving the problems of the technologies described above, a kind of sheet type quartz crystal resonator of the present utility model, comprise pedestal, metal top cover, quartz wafer, electrode, be provided with the LMP metallic packaging layer that one deck thermosol closes sealing between wherein said metal top cover and the pedestal, the metal top cover thermosol closes seal cover and is located on the pedestal.
Above-mentioned a kind of sheet type quartz crystal resonator, be provided with groove in the described pedestal and extend to the tank of base bottom surface by the groove both sides respectively, described quartz wafer and electrode are separately fixed in the groove and tank of pedestal, and electrode is electrically connected with quartz wafer by conducting resinl.
After the utility model adopts said structure, by the metallic packaging layer is set between metal cap and pedestal, after being coated with the metallic packaging layer on the pedestal and by direct heating, just can make the fused one that is sealed into of metal cap and pedestal in advance during encapsulation, advantage such as compared with prior art have good airproof performance, production and processing technology is simple, and the strong and ageing resistance of impact resistance is good; Further improve the inner structure that connects, fixedly mounts quartz wafer on this basis, the tank of offering groove in the pedestal and leading to the bottom outward, integrated solid quartz wafer realizes that with the cramped construction that electrode also is connected volume is little and guaranteed operational quality, has simplified production technology simultaneously and has reduced production cost.
The utility model has adapted to the requirement of electronic devices and components to miniaturization, large-scale development, can realize the technique effect that the automation surface mounts, and is specially adapted to the high accuracy electrical equipment use that mobile phone, notebook computer etc. take up room little.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of concrete enforcement state of the utility model.
Among the figure: 1 is pedestal, and 11 is substrate, and 12 is last deckle board, and 1a is a groove, and 1b is a tank, and 2 is loam cake, and 3 is quartz wafer, and 4 is electrode, and 5 is LMP metallic packaging layer.
Embodiment
As shown in Figure 1, a kind of sheet type quartz crystal resonator, comprise pedestal 1, metal top cover 2, quartz wafer 3, electrode 4, be provided with the LMP metallic packaging layer 5 that one deck thermosol closes sealing between metal top cover 2 and the pedestal 1, metal top cover 2 thermosols close seal cover and are located on the pedestal 1.
Be provided with groove 1a in the pedestal 1 and extend to the tank 1b of pedestal 1 bottom surface respectively by groove 1a both sides, quartz wafer 3 and electrode 4 are separately fixed among the groove 1a and tank 1b of pedestal 1, and electrode 4 is electrically connected with quartz wafer 3 by conducting resinl.
The utility model is coated with LMP metallic packaging layer 5 back in advance and can makes just by direct heating that metal top cover 2 and pedestal 1 are fused to be sealed into one when concrete encapsulation on pedestal 1, simplified processing technology greatly.
Above-described embodiment only is a preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make the adjustment and the improvement of some structures, these also should be considered as belonging to protection range of the present utility model.
