The resonator can realize small-sized surface mount, meanwhile, the structure is simple, and the manufacture cost is low.
Description
Technical field
The utility model provides a kind of design of SMD quartz-crystal resonator, and particularly a kind of is the crystal resonator of structure with metal top cover, glue or seal glass, base of ceramic.
Background technology
Surface mount design and reduce the development trend that size is a quartz-crystal resonator.The crystal resonator that production is arranged at present can be divided into two types, and one uses leaded device, with former lead-in wire bending, and increases insulating trip, form the surface mount form, but volume is big, is unfavorable for the miniaturization of product.Another uses the multilayer co-firing ceramic structure, and still, this kinds of structures complexity is manufactured the cost height.
Therefore, industry is looked forward to always and a kind ofly can be taken into account small size, low cost, simple in structure, well behaved quartz-crystal resonator.
Summary of the invention
Based on the problems referred to above, the purpose of this utility model provides a kind of surface sticked quartz crystal resonator, and this resonator can be realized the small size surface mount, and is simultaneously simple in structure, to manufacture cost low.
The resonator of its a series of overall dimensions that realize comprises: 8045,7050,6035,5032,3225,2520,2016.
For achieving the above object, the utility model is achieved in that
A kind of surface sticked quartz crystal resonator with loam cake, it is characterized in that this resonator comprise reeded metal top cover, be coated with metal electrode quartz wafer, the base of ceramic of internal and external conductor is arranged; The metal top cover inboard has groove, and metal top cover is fixed on the base of ceramic by sticking cementing or seal glass, forms an airtight cavity, has electrode on the quartz wafer, and is fixed on the pedestal by conductive adhesive.
Shown in metal top cover, quartz wafer is covered in its groove, form airtight protection cavity, quartz wafer is at this cavity interior resonance, and is protected.
Described base of ceramic, it fixedly is provided with the pad of conduction in the position of quartz crystal, and described pad extends to the edge of pedestal, to be electrically connected with the outside.
Further, four angles of base of ceramic are provided with pad, to satisfy the requirement of various quartz wafers.
Described electrode can be made of single-layer metal film or two-layer above metal film.
Land pattern on the described base of ceramic can be according to the position design of wafer, individual layer or two-layer above pad can be set on the base of ceramic, pad is the two-sided conductor of single-layer ceramic at least, can pass through conducting of position, hole or side conducting at the pad of coplanar not, support quartz wafer and the fixedly surface setting of the pad protrusion base of ceramic of conducting resinl position, pad adopts printing or engraving method to form.
By above-mentioned structure setting, the utility model can reduce the size of manufacturing of quartz-crystal resonator effectively, simultaneously, of the present utility model simple in structure, be easy to realize.
And the utility model can be realized the quartz-crystal resonator of multiple model.
Description of drawings
Fig. 1 is a groove shaped metal top cover schematic diagram.
The structural representation that Fig. 2 implements for the utility model.
Embodiment
Below, in conjunction with the accompanying drawings shown in, the concrete enforcement of this utility model is elaborated.
Enforcement of the present utility model provides the surface sticked quartz crystal resonator that a kind of simple in structure, suitable small size requires.
Wherein, Figure 1 shows that the structural representation of metal top cover, shown in the figure, groove shaped metal top cover 1 uses the material close with ceramic thermal coefficient of expansion, as cutting down thin slice, adopts repeatedly punch forming, and cuts off.And the nickel plating protection is adopted on loam cake metal 1 surface.
