Background technology
Known attachment quartz-crystal resonator its there is baroque shortcoming, and cost is higher.As the miniaturization along with terminal electronic product, all require miniaturization to components and parts used, the miniaturization of quartz-crystal resonator is also the inexorable trend of development.Current SMD quartz resonator adopts conducting resinl that the spring leaf of the quartz wafer and pedestal that are coated with electrode is bonded together, and add that insulation spacer is made in bottom, complex structure, cost is high.Along with the Fast Growth of consumption electronic products (as mobile computer, digital camera, mobile phone, e-book etc.), in order to cater to the market demand, low cost product is the very important ring that dominates the market, but in the process that production cost reduces, involution material is the difficult problem that its cost declines, and therefore the quartz-crystal resonator of low cost is also the large key element needing in design to overcome.
Utility model content
The purpose of this utility model is to solve the good airproof performance that above-mentioned the deficiencies in the prior art provide a kind of, a kind of novel quartz-crystal resonator that cost is low.
To achieve these goals, a kind of novel quartz-crystal resonator designed by the utility model, comprise crystal resonator, the upper cover that described crystal resonator mainly comprises pedestal and is placed on pedestal, oscillator, metal electrode, wafer and conductive silicon, wafer is placed on pedestal, conductive silicon is placed on oscillator, metal electrode is placed in the upper surface of wafer and is connected with conductive silicon, oscillator is placed between pedestal and wafer, what this pedestal has placement stem draws hole, oscillator is placed in and draws upper end surface, hole, it is characterized in that: described pedestal is provided with groove, wafer is placed in groove, and the height of the upper surface of wafer is no more than pedestal upper surface, above-mentioned stem one end is placed in be fixed through pedestal and above-mentioned oscillator, the stem end of this end is provided with circular ring plate, thickness in the middle of described metal electrode is greater than the thickness at its edge.
Preferably, described upper cover and pedestal are provided with sealing layer of resin between the two, and upper cover and pedestal seal fixing by sealing layer of resin.
Preferably, described described upper cover the inner is coated with drying resin.
Preferably, described pedestal lower end is also fixed with insulation spacer.
A kind of novel quartz-crystal resonator that the utility model obtains, the varied in thickness of the upper metal electrode of quartz-crystal resonator is utilized to improve and strengthen the performance of resonator, described substrate and upper cover are tightly connected by sealing layer of resin, sealing effectiveness is very good, adopts circular ring plate, adds the raising bonding strength of wafer and lead-in wire, reach and improve the vibration resistance of product and the object of frequency stability, save raw material, reduce manufacturing cost, there is good economic benefit.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is with drying resin structure schematic diagram in Fig. 1.
In figure: pedestal 1, upper cover 2, wafer 3, conductive silicon 4, metal electrode 5, stem 6, sealing layer of resin 7, groove 8, insulation spacer 9, resin 10, oscillator 41, circular ring plate 61.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As Fig. 1, shown in Fig. 2, a kind of novel quartz-crystal resonator that the utility model provides, comprise crystal resonator wafer, described crystal resonator mainly comprises pedestal 1 and is placed in the upper cover 2 on pedestal, oscillator 41, metal electrode 5, wafer 3 and conductive silicon 4, wafer 3 is placed on pedestal 1, conductive silicon 4 is placed on oscillator 41, metal electrode 5 is placed in the upper surface of wafer and is connected with conductive silicon 4, oscillator 41 is placed between pedestal 1 and wafer 3, what this pedestal 1 has placement stem 6 draws hole, oscillator 41 is placed in and draws upper end surface, hole, described pedestal 1 is provided with groove 8, wafer 3 is placed in groove 8, and the height of the upper surface of wafer is no more than pedestal upper surface, Appropriate application space, the volume of quartz-crystal resonator can be reduced, above-mentioned stem 6 one end is placed in be fixed through pedestal and above-mentioned oscillator, the stem end of this end is provided with circular ring plate 61, the diameter of circular ring plate 61 is greater than the diameter of stem, thickness in the middle of described metal electrode is greater than the thickness at its edge, improve performance, described pedestal 1 lower end is also fixed with insulation spacer 9, insulation spacer 9 is also be provided with the hole allowing stem draw.
Preferably, described upper cover 2 is provided with sealing layer of resin 7 between the two with pedestal 1, and upper cover and pedestal seal fixing by sealing layer of resin.
Preferably, described described upper cover the inner is coated with drying resin 10.
A kind of novel quartz-crystal resonator that the utility model obtains, the varied in thickness of the upper metal electrode of quartz-crystal resonator is utilized to improve and strengthen the performance of resonator, described substrate and upper cover are tightly connected by sealing layer of resin, sealing effectiveness is very good, adopt circular ring plate 61 or also can take to come directly towards surface and increase twill, the measures such as step, namely design without spring leaf, add the raising bonding strength of wafer and lead-in wire, market miniature requirement can be met, reach and improve the vibration resistance of product and the object of frequency stability, decrease the welding sequence of spring leaf and lead-in wire simultaneously, save raw material, reduce manufacturing cost, there is good economic benefit, described substrate and upper cover are tightly connected by sealing layer of resin, sealing effectiveness is very good, make the frequency of resonator more reliable and more stable, thus significantly reduce material cost, instead of the metal involution formula ceramet encapsulation crystal oscillator that original cost is higher, achieve low cost, small size, the quartz-crystal resonator of high freuqency accuracy.
