Abstract
The invention relates to a surface mounting type quartz crystal resonator metal seal welding electrode; and the electrode is characterized in that the inclination angle of the seal welding surface of the seal welding electrode wheel is 12+/-1 degrees. The invention has the following advantages: by controlling the inclination angle of the seal welding surface of the seal welding electrode wheel, the welding of a metal cover plate and a ceramic base seal welding ring can be realized; and on the basis of the preparation of the resonator, metal spatters generated in the seal welding process can be reduced, the metal substances attached to the quartz plate can be greatly reduced, the frequency variation of the surface mounting type quartz crystal resonator before and after seal welding is within +/-5ppm, the dependency of the drive level can not be damaged and the quality of the resonator can be increased.
Description
Technical field
What the present invention relates to is a kind of surface attaching type quartz-crystal resonator metal soldering and sealing electrode, belongs to quartz crystal unit manufacturing technology field.
Technical background
Development along with electronics and information industry, to the frequency accuracy of quartz-crystal resonator and the more and more strictness of requirement of stability, from middle nineteen nineties in last century ± specification requirement of 500ppm adds sternly step by step, so far, there has been the margin of tolerance of the product order requirements frequency of significant proportion to be ± 10ppm, and from there not being level of drive characteristic to require to develop into today nearly all order at first very strict requirement arranged.These strict demands have just proposed very high requirement to the course of processing and the manufacturing process of product, and the disappearance of any one details all might cause the decline of yield.Therefore the control of each step seems important unusually in the course of processing.The variable quantity of tradition soldering and sealing electrode institute's product processed frequency before and after soldering and sealing is bigger, and level of drive dependency characteristic also has significantly deterioration simultaneously.The angle of inclination of soldering and sealing electrode wheel soldering and sealing face as shown in Figure 1 is 8 ± 1 °, it is less that the soldering and sealing face of soldering and sealing electrode wheel touches the area of metal cover board and base of ceramic soldering and sealing ring in the soldering and sealing process, local welding temperature is higher, and the skin of cover plate is nickel plating, in the process that high-temperature soldering connects, be very easy to produce splash, and 8 ± 1 ° angle of inclination also is very easy to make splash to enter the inside of product soldering and sealing housing, be attached on the quartz plate, cause the deterioration of product frequency difference and level of drive dependency characteristic.
Summary of the invention
The present invention proposes a kind of surface attaching type quartz-crystal resonator metal soldering and sealing electrode, be intended to overcome the above-mentioned defective of existing in prior technology, and the frequency variation of product can be controlled within ± 5ppm before and after the soldering and sealing of the present invention, and can cause the deterioration of level of drive dependency characteristic hardly, very large advantage is arranged.
Technical solution of the present invention: the angle of inclination that it is characterized in that soldering and sealing electrode wheel soldering and sealing face is 12 ± 1 °.
Specifically with the angle of inclination of existing change soldering and sealing electrode wheel soldering and sealing face, change into 12 ± 1 ° from 8 ± 1 °,
Advantage of the present invention: based on the deficiency of traditional soldering and sealing electrode, in the new soldering and sealing electrode of design, changed the soldering and sealing face tilt angle of soldering and sealing electrode wheel, the angle of inclination is designed to 12 ± 1 °.On the basis that guarantees the soldering and sealing airtight effect, the soldering and sealing electrode wheel makes that by the change of angle the soldering and sealing face of electrode wheel touches the soldering and sealing ring that more place is base of ceramic in the soldering and sealing process, the welding of metal cover board and soldering and sealing ring is expanded to the periphery, and the soldering and sealing ring surface of base of ceramic is gold-plated, in the process of high temperature welding, be not easy to produce splash, reach the effect of frequency change and the improvement of level of drive dependency characteristic with this.
Description of drawings
Accompanying drawing 1 is traditional surface attaching type quartz-crystal resonator soldering and sealing schematic diagram.
Accompanying drawing 2 is surface attaching type quartz-crystal resonator soldering and sealing schematic diagrames of the present invention.
Among the figure 1 is metal cover board, the 2nd, base of ceramic, the 3rd, conducting resinl, the 4th, quartz water wafer, the 5th, soldering and sealing ring, the 6th, soldering and sealing electrode wheel.
Embodiment
Contrast accompanying drawing 2, surface attaching type quartz-crystal resonator metal soldering and sealing electrode, its structure comprises metal cover board 1, soldering and sealing electrode wheel 6, base of ceramic 2, conducting resinl 3, quartz plate 4, soldering and sealing ring 5, wherein metal cover board 1 is between soldering and sealing electrode wheel 6 and soldering and sealing ring 5, soldering and sealing ring 5 is parts of base of ceramic 2, and the quartz plate 4 in the base of ceramic 2 touches with base of ceramic 2 mutually by establishing conducting resinl 3.The present invention changes into 12 ± 1 ° with the angle of inclination of soldering and sealing electrode wheel 6 soldering and sealing faces from existing 8 ± 1 °.Thereby make that electrode wheel 6 soldering and sealing faces touch the soldering and sealing ring that more place is base of ceramic 2 in the soldering and sealing process, and soldering and sealing ring 5 extexines of base of ceramic are gold-plated, with the process of metal cover board 1 high temperature welding in be not easy to produce the metal splash, there is not metal to be splashed on the quartz plate 4, soldering and sealing process so has influence on frequency and the level of drive dependency characteristic of product hardly, reaches the effect of improving product frequency change and level of drive dependency characteristic with this.
