The base structure of the quartz resonator provided by the utility model has the technical advantages that: because the groove on which the quartz wafer is mounted is directly arranged on the base plate, the integral thickness of the product is lowered, and the base structure is simplified so as to cause the product to be more miniaturized; the base structure avoids multilayer stacking, and prevents air leakage and foam formation in the packaging; and in addition, the groove is internally provided with the supporting part, therefore the quartz wafer can be stably arranged in the groove and the stability is ensured.
Description
Technical field
The utility model relates to quartz resonator, relates in particular to a kind of pedestal of the GLASS soldering and sealing quartz resonator that mounts.
Background technology
Development along with electronic technology, technology; The direction evolution of quartzy product since nineteen ninety towards SMD; Beginning in 1998 develops to the direction of small-sized SMD again, therefore compact competition also just from then on fieriness get up, develop into 4025 products from SMD-8045,7050,6035,5032 now; For adapting to this miniaturization development, 3225 more small-sized type quartz resonators arise at the historic moment.The quartz crystal of miniaturization generally uses traditional SEAM sealing welding technique for extra on the other hand; The material requested cost is than higher; The processing mode more complicated; Make 3225 type quartz resonators and just seem particularly important and attempt other soldering and sealing production technologies, its advantage and don't reduce under the situation of product quality relatively, we select GLASS soldering and sealing production technology to accomplish 3225 type quartz resonators.
Existing pedestal has carried out repeatedly improving, and the SMD type mainly is a ceramic resonators at present, and it was can cut down plate (Kovar) with the GLASS material to have replaced iron cobalt nickel alloy material upper cover plate to encapsulate with respect to the past, because piezolectric crystal unit has certain thickness; So in order to adapt to the needs of this cover plate, be provided with between GLASS cover plate and the substrate certain thickness on deckle board and middle deckle board, last deckle board; Pass through lamination, binder removal, thermal sintering between middle deckle board and the substrate; Its shortcoming is, owing to being multilayer, so processing technology is complicated; And cause became uneven easily after the multilayer stack, be easy to cause gas leakage, foaming phenomenon after the encapsulation, therefore to technology; Temperature, equipment etc. all have very high requirement, and product percent of pass is lower.
Summary of the invention
The utility model provides a kind of simple in structure to the deficiency that exists in the above-mentioned prior art, and gas leakage in the time of can effectively avoiding encapsulating reduces product thickness, the base construction of quartz resonator easy to process.
The technical scheme of the utility model is achieved in that
The base construction of quartz resonator; Include substrate, electrode and external electrode on the front and back of substrate, being respectively equipped with also offer conductive trough on front, the back side and the sidewall of substrate; And in conductive trough, be printed be communicated with in the conducting wire of electrode and external electrode; Be provided with in the centre of substrate front side one mount quartz wafer groove, interior electrode is arranged on the end in the groove, the other end in groove is provided with the support portion; Electrode comprises electrode in two be provided with at interval positive and negative in described, and the height of positive and negative interior electrode is identical with the height of support portion; Described external electrode comprises positive and negative external electrode and two dummy electrodes, and positive and negative external electrode and two dummy electrodes are distributed in four edges of substrate back, positive and negative external electrode through conductive trough, conducting wire with positive and negative in electrode link to each other.
As preferably, in positive and negative electrode other respectively be provided with one be used for when pedestal is gold-plated, being communicated with each substrate guide groove.
As preferably, the conductive trough at the substrate front side and the back side is opened in the edge of substrate, and the conductive trough on the sidewall is opened on the sidewall rib of substrate.
Adopted the beneficial effect of the utility model of technique scheme to be:
Because the groove that mounts quartz wafer is directly to be opened on the substrate, so reduced the integral thickness of product, has simplified base construction, make product miniaturization more; Avoided the multilayer stack simultaneously, gas leakage when preventing to encapsulate, the generation of foaming phenomenon; In addition, in groove, also be provided with the support portion, the height of described support portion is identical with the positive and negative electrode height of interior electrode, thereby can make when quartz wafer is installed in the groove, can not produce rugged phenomenon, thereby guarantee its stability.
And it is more attractive in appearance in appearance in order to make; Described external electrode comprises positive and negative external electrode and two dummy electrodes; Positive and negative external electrode and two dummy electrodes are distributed in four edges of substrate back, positive and negative external electrode through conductive trough, conducting wire with positive and negative in electrode link to each other.
