Abstract
The utility model relates to a quartz crystal resonator packaged by a concave cover. A metal packaging cover is designed into a concave shape first, then a quartz wafer is fixed in a cavity of a ceramic base by silver glue, the concave metal packaging cover and the ceramic base are glued together by epoxy resin, which is cured after being baked for one hour under the temperature of 150 degrees, and thus a sealing space required for a quartz crystal to work is formed. By packaging the metal concave cover and the ceramic base with epoxy resin and omitting the manufacture of high-difficulty ceramic base metallization process and metallization packaging process, the process control of a surface-mounted quartz crystal resonator (oscillator) is greatly simplified, and the manufacturing cost can be decreased by about 25%.
Description
Affiliated technical field
The utility model relates to a kind of frequency electronic component quartz-crystal resonator (oscillator), the surface mounting quartz crystal resonator of the recessed cap seal dress of especially a kind of usefulness.
Background technology
At present, surface mounting quartz crystal resonator (oscillator) generally comprises quartz wafer, ceramic metallization pedestal and metal flat cover, quartz wafer is adhesively fixed by elargol and base of ceramic, metal flat cover and ceramic metallization pedestal can cut down ring and form the required dustless seal cavity of quartz wafer work by the seam welder high-temperature soldering, because the ceramic metallization pedestal manufacture technology complexity that present surface mounting quartz crystal resonator (oscillator) industry is required, the seam welder of encapsulation usefulness only has imported product, and the control of process for sealing parameter is complicated, thereby cause resonator (oscillator) finished product rate not high, expensive.
Summary of the invention
In order to overcome existing surface mounting quartz crystal resonator (oscillator) production complex process, qualification rate is low, cost is high deficiency, the utility model provides a kind of recessed cap seal dress quartz-crystal resonator, not only packaging technology control is simple for it, and can improve product percent of pass, reduce cost of manufacture.
The technical scheme that its technical problem that solves the utility model adopts is: first metal cover is designed to spill, be fixed on quartz wafer in the cavity of base of ceramic by elargol again, the recessed lid of concave metal and base of ceramic pass through adhering with epoxy resin, through baking under 150 ℃ of conditions epoxy resin is solidified, can form the required seal cavity of quartz crystal work.
The beneficial effects of the utility model are: adopt epoxy encapsulation owing to adopt between the recessed lid of metal and the base of ceramic, this just omits makes highly difficult base of ceramic metallization processes and metallization packaged operation, surface mounting quartz crystal resonator (oscillator) technology controlling and process is simplified greatly, and manufacturing cost can descend about 25%.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical view that a kind of recessed cap seal dress quartz-crystal resonator of the utility model is removed the recessed lid of metal.
Fig. 2 is a kind of recessed cap seal dress quartz-crystal resonator structural representation of the utility model.
Among the figure: 21, the recessed lid of metal, 22, quartz wafer, 23, base of ceramic, 24, epoxy resin, 25, elargol.
Embodiment
As shown in Figure 1 and Figure 2, first metal cover is designed to spill, again quartz wafer (22) is fixed in the cavity of base of ceramic (23) by elargol (25), the recessed lid of concave metal (21) is bonding by epoxy resin (24) with base of ceramic (23), through baking under 150 ℃ of conditions epoxy resin (24) is solidified again, can form the required seal cavity of quartz crystal work.
Claims (2)
1. a recessed cap seal fills quartz-crystal resonator, and it comprises metal cover, and quartz wafer (22) is fixed in the cavity of base of ceramic (23) by elargol (25), it is characterized in that: metal cover is designed to the recessed lid of concave metal (21).
2. a kind of recessed cap seal according to claim 1 fills quartz-crystal resonator, it is characterized in that: the recessed lid of concave metal (21) is bonding by epoxy resin (24) with base of ceramic (23).
