Description

A kind of quartz-crystal resonator

Technical field

A kind of resonator that the utility model relates to refers in particular to a kind of 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 precision 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 technology that its base of ceramic adopts lamination, burns altogether, has the complex structure shortcoming, and, make that the production cost of base of ceramic is high always, and output also is subjected to the restriction of technology, equipment each side because the inconsistent meeting of percent of firing shrinkage of pottery and metal paste causes the problem of bottom slab warping distortion, can not be satisfied with the growing market demand far away, 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 provide a kind of simple in structure, volume is little, cost is low, impact resistance is strong, the simple quartz-crystal resonator of production and processing technology.

For solving the problems of the technologies described above, a kind of quartz-crystal resonator of the present utility model, this resonator is made of ceramic bottom laminate, ceramic cap, wafer, the both sides of ceramic bottom laminate plate face and bottom surface are provided with corresponding inside printing terminal and outside printing terminal is electrically connected by the metal wire in the via, and described wafer is bonded on the inner printing terminal by conducting resinl; Ceramic cap is provided with the groove of wafer, and ceramic cap and ceramic bottom laminate are tightly connected by low molten glass seal layer.

Above-mentioned a kind of quartz-crystal resonator, the thickness of slab of described ceramic bottom laminate is not less than 0.6mm, carries out stable vibration to guarantee wafer, and absorbs the external impact be applied on the wafer to a certain extent and protect wafer.

Above-mentioned a kind of quartz-crystal resonator, the thickness of described inner printing terminal is not less than 50 μ m, guarantees to make wafer play effective vibration.

Above-mentioned a kind of quartz-crystal resonator, described inner printing terminal and outside printing terminal are argent.

After the utility model adopts said structure, by adopting plane ceramic bottom flaggy to simplify the structure, in via, inject metal and form metal wire, inner printing terminal and outside printing terminal are arranged on the ceramic bottom flaggy by printing and conduct by metal wire, need not to consider the pottery owing to burning altogether and the inconsistent problem that causes bottom slab warping distortion of percent of firing shrinkage of metal paste, so, when sintering, can ignore pottery and generally the flexural deformation of the crystal oscillator ceramic packaging that cause inconsistent with the thermal expansion metal coefficient as long as print thickness is guaranteed.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.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but does not constitute any restriction of the present utility model.

Fig. 1 is the structural representation of a kind of concrete enforcement state of the utility model.
