Abstract
The utility model relates to a chip type quartz crystal resonator comprising a base (1), an upper cover (2), a quartz crystal plate (3) and an electrode (4), wherein a groove (1a) and containing grooves (1b) which respectively extend to the bottom of the base (1) from both sides of the groove (1a) are arranged in the base (1), wherein the quartz crystal plate (3) and the electrode (4) are respectively fixed in the groove (1a) and the containing grooves (1b) of the base (1), the electrode (4) is electrically connected with the quartz crystal plate (3) through conducting resin, and the upper cover (2) is covered on the base (1) in a sealing mode. The resonator has the technical effects of small volume, low cost, strong shock resistance, simple manufacturing and processing technique 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 traditional quartz-crystal resonator of China is mainly produced by labour-intensive, and its efficient is low, profit is meagre and production technology does not have substantive breakthroughs, and its size is bigger, is mainly used on the low-grade electronic products such as toy for children, game machine, television set.And be used for ask for something on the high accuracy electronic products such as mobile phone, notebook computer, satellite communication device take up room little can surface-pasted crystal resonator, the production core technology of oscillator, filter base of ceramic grasps hand abroad always.The known quartz-crystal resonator that mounts; the kind pattern of this transformation is a lot; as on the 49S product, having added the ambroin pad; the pin of 49S resonator is fallen to two lateral bendings; reach the purpose of the accurate SMD crystal of surface mount; this accurate SMD crystal is convenient to accomplish scale production; but volume is big and thickness thick (surpassing 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; precision is relatively poor; thereby cause rosin joint; the phenomenon of dry joint causes reprocessed product to increase, thereby cost is increased; production efficiency descends, and product quality reduces.Therefore, how to address the above problem, become problem demanding prompt solution.
The utility model content
The technical problems to be solved in the utility model provides that a kind of volume is little, cost is low, impact resistance is strong, the simple sheet type quartz crystal resonator of production and processing technology.
For solving the problems of the technologies described above, a kind of sheet type quartz crystal resonator of the present utility model, comprise pedestal, loam cake, quartz wafer, electrode, wherein: 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, electrode is electrically connected by conducting resinl and quartz wafer, and the loam cake seal cover is located on the pedestal.
The described pedestal of above-mentioned sheet type quartz crystal resonator adopts ceramic material.
The above-mentioned described pedestal of sheet type quartz crystal resonator by substrate, go up deckle board by epoxy resin or low temperature glass is bonding constitutes, groove is arranged in the deckle board, tank is arranged in the substrate.
After the utility model adopts said structure; by in pedestal, offer groove and outside lead to the bottom tank; integrated solid quartz wafer is realized that volume is little and has been guaranteed operational quality with the cramped construction that electrode also is connected; simplified production technology simultaneously and reduced production costs; adapted to the requirement of electronic devices and components to miniaturization, large-scale development; can realize the technique effect that the automation surface mounts, be specially adapted to the high accuracy electrical equipment use that mobile phone, notebook computer etc. take up room little.
The utility model further improves wherein base of ceramic, the base of ceramic that is made of substrate, middle plate and upper ledge can adopt the individual layer sintering, can not produce local contraction, foaming, layering and cracking phenomena, realize that potsherd thickness is all even indeformable, the smooth technique effect that makes cover plate encapsulation back guarantee sealing of base of ceramic external shape.
