Description
Technical field
The utility model relates to a kind of quartz-crystal resonator, particularly a kind of surface sticked quartz crystal resonator.
Background technology
At present, known quartz-crystal resonator has a variety of forms.Known a kind of, it also is the quartz-crystal resonator of band lead-in wire forms such as most of 49U types that adopt and 49S type, the quartz-crystal resonator price of this band lead-in wire is not high, but the shortcoming that it exists is 1. bulky, and the volume of 49U product is 13.5 * 11.5 * 5mm
3, the volume of 49S product is 10.5 * 3.8 * 3.5mm
32. because 49U product and 49S product adopt is spring or reed structure, thus yielding, and impact resistance and ageing resistace are poor; 3. because this resonator has lead-in wire, can not automation mount, be difficult to realize the large-scale production of product, have a strong impact on production efficiency.Lighting day by day, miniaturization, scale, cost degradation along with household appliances and electronic product; the quartz-crystal resonator of this band lead-in wire is difficult to make it to be applied in small household appliances class and the electronic product and goes; the scope of application is restricted, and has certain limitation.The known quartz-crystal resonator that mounts that also has transformation, the kind pattern of this transformation is a lot, have plenty of and on the 49S product, added the ambroin pad, the pin of 49S resonator is fallen to two lateral bendings, reach surface-pasted purpose and (be called for short " accurate SMD crystal "), this accurate SMD crystal is convenient to accomplish scale production, but volume is huger, and thickness surpasses 4.0mm, can't be applied in small household appliances class and the electronic product, and this kind product lead-in wire is difficult to accomplish that the location is consistent, and precision is relatively poor, thereby causes rosin joint, the phenomenon of dry joint, cause reprocessed product to increase, thereby cost is increased, and production efficiency descends, and product quality reduces; The product that also has is at the two sides of the brilliant English susceptor body of stone difference sintering top electrode and bottom electrode, this product is owing to the reason of sintered location causes sintering inconvenience easily, and easily causing phenomenons such as rosin joint, dry joint, sealing-off, product quality to be difficult to guarantee, cost also is difficult to reduce.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of volume is little, cost is low, impact resistance is strong, ageing resistance is good, can realize the quartz-crystal resonator that the automation surface mounts.
The technical scheme that realizes above-mentioned purpose is: a kind of surface sticked quartz crystal resonator, comprise pedestal, lower electrode film, quartz wafer, upper electrode film, loam cake, top electrode, bottom electrode, loam cake be fixed in pedestal above, pedestal is whole groove structure, quartz wafer is fixed on the upper bottom surface of pedestal by conducting resinl, upper electrode film is fixed on the upper surface of quartz wafer, lower electrode film is fixed on the lower surface of quartz wafer, and top electrode and bottom electrode are fixed in the groove of pedestal bottom surface in pairs.
After adopting technique scheme, brought very big benefit: (1) volume is little.Can reach 4 * 2.5 * 0.8mm such as the 4025SMD volume
3, even can also be littler, this surface sticked quartz crystal resonator volume reduces greatly, has adapted to the requirement of electronic devices and components to miniaturization, large-scale development, can realize that the automation surface mounts; (2) cost is low.Because bottom electrode and top electrode are fixed in the groove on the bottom surface of pedestal very dexterously, weld, operations such as sintering is very convenient, not only guaranteed operational quality, and running cost descends greatly also; Moreover because pedestal is arranged to overall structure, and the material of loam cake and pedestal can be selected different material for use, such as the pedestal ceramic material, and loam cake can be selected metal material for use, thereby cost of material descends, and owing to realized surface mount truly, thereby can accomplish scale production, production efficiency improves, and production cost reduces, it is popular to be convenient to product, and the crowd is accepted by ordinary consumption; (3) good product quality.Owing to do not have spring or reed structure, thereby avoided that band lead-in wire quartz-crystal resonator is yielding, the shortcoming of impact resistance and ageing resistance difference, has good characteristic, simultaneously since its top electrode and bottom electrode be fixed in the groove of bottom surface of pedestal, solder joint is big, be difficult for causing phenomenons such as rosin joint, dry joint, sealing-off, its performance is guaranteed, make good product quality; (4) applied widely.Because loam cake, pedestal can be selected multiple material for use, have both reduced cost, have guaranteed performance again, the user can carry out multiple choices according to cost performance, has satisfied requirements of different users, and its scope of application is wider.
