The surface-mounted ceramic packaging quartz crystal resonator of the utility model has the advantages of low processing cost, simple production preparation process, and high use reliability.
Description
Technical field
The utility model relates to a kind of quartz-crystal resonator, is specifically related to a kind of quartz-crystal resonator of surface mount pottery envelope.
Background technology
At present, surface mounting quartz crystal resonator generally comprises quartz crystal, metal flat cover and metallized ceramic pedestal, and quartz crystal is closed in metal flat cover and the formed space of metallized ceramic pedestal.Surface mounting quartz crystal resonator is in the process of producing, and the metal flat cover fixes by mode and the metallized ceramic pedestal of welding, thereby forms the required clean nitrogen-filled seal space of quartz crystal resonance.
Because metallized ceramic pedestal cost is very high, the metal current base of ceramic only has Kyocera, the Sumitomo, three volume productions of NTK, domestic only have three ring groups to test-manufacture on a small quantity, the basic dependence on import of SMD quartz-crystal resonator production, and the metal flat cover is welded in the proprietary seam-welding equipment of process need of metallized ceramic pedestal, and import price is expensive, the seam-welding equipment operation is to the roll welding electric current, pressure, the parameter requests such as speed are quite strict, be easy to cause the gas leakage of product solder skip or pedestal pressure break bad, operative skill to the operating personnel is had relatively high expectations, therefore preparation process is complicated, causes the production cost of surface mounting quartz crystal resonator high.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of quartz-crystal resonator of surface mount pottery envelope, thereby solves the problem in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of quartz-crystal resonator of surface mount pottery envelope, comprise ceramic substrate, ceramic recessed lid and quartz crystal, it is characterized in that, the recessed lid of described pottery is provided with the spill container cavity, and spiral-lock is on described ceramic substrate, described quartz crystal is fixed on the described ceramic substrate, and is positioned at the spill container cavity; Described ceramic substrate is provided with for the pit for described quartz crystal oscillatory work.This pit forms the desired unsettled zone of described quartz crystal oscillatory work by the technological forming that sandblasts.
As a kind of improvement, utilize adhering with epoxy resin to fix between described ceramic substrate and the recessed lid of described pottery.
As a kind of further improvement, described ceramic substrate forms annular storage glue groove by the technique that sandblasts, and annular storage glue groove can store unnecessary epoxy resin, can not cause and overflow glue and pollute quartz crystal, has improved product yield.
As a kind of improvement, described quartz crystal utilizes elargol to be fixed on the described ceramic substrate.
Obviously, those skilled in the art should know, and need to arrange circuit on the described ceramic substrate, generally adopt vacuum sputtering coating to form circuit, have good conductivity, can satisfy conductivity and weld strength requirement.
