Description
Technical field
The utility model relates to a kind of quartz-crystal resonator, particularly a kind of quartz-crystal resonator with novel spot gluing structure.
Background technology
Quartz-crystal resonator is also known as quartz crystal, and be the resonant element utilizing the piezoelectric effect of quartz crystal and make, itself and semiconductor device use together with Resistor-Capacitor Unit, forms quartz oscillator.Quartz oscillator is the oscillator of high accuracy and high stability, be widely used in all kinds of oscillating circuits such as television set, computer, automobile, and for frequency generator, provide reference signal for data processing clocking with for particular system in communication system.Surface-mounted integrated circuit often can use 49S quartz-crystal resonator, and this kind of quartz-crystal resonator generally comprises the compositions such as pedestal, shell, quartz wafer, conducting resinl, metal electrode.As shown in Figure 1, the shortcoming of current this structure is: 1, adopt 4 glue, glue spot size is larger; 2, glue point position is at wafer Chang Bian center, is unfavorable for crystal vibration; 3, glue point ambient stress is large, and during high excitation, concealed wire defect (DLD) value is bigger than normal.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides that a kind of structure is simple, some glue size is little, technique simple, have the quartz-crystal resonator of novel spot gluing structure.
The technical scheme that the utility model adopts is: the utility model comprises pedestal, quartz wafer, the metal electrode being arranged on described quartz wafer both sides, lead-in wire and the conducting resinl for being communicated with described metal electrode and affiliated lead-in wire, and described conducting resinl is positioned at the corner place of described quartz wafer.
The utility model also comprises the electrode ear be connected with described metal electrode, and described electrode ear is extended to the corner place of described quartz wafer and is connected with described lead-in wire by described conducting resinl.
Described electrode ear is Y type, and described electrode ear one end of Y type is connected with described metal electrode, and two ends extend to the Liang Jiaochu of described quartz wafer in addition.
The bonding area of described conducting resinl is no more than the half of described electrode ear area.
The beneficial effects of the utility model are: because the utility model adopts the design of 8 glue, it comprises pedestal, quartz wafer, be arranged on the metal electrode of described quartz wafer both sides, lead-in wire and the conducting resinl for being communicated with described metal electrode and affiliated lead-in wire, described conducting resinl is positioned at the corner place of described quartz wafer, so, the utility model structure is simple, point glue size is little, technique is simple, glue point is positioned at the corner of described quartz wafer, thus the more former technique of resistance reduces 20%, DLD then reduces 15%, the change of some plastic structure, improve crystal vibration vigor, reduce resistance, overcoming the problem of in the past sacrificing intermediate frequency crystal anti-drop for reducing resistance, having positive meaning to the supporting of current handheld mobile device.
Accompanying drawing explanation
Fig. 1 is the structural representation of conventional quartz crystal resonator;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2, in the present embodiment, the utility model comprises pedestal 1, quartz wafer 2, the metal electrode 3 being arranged on described quartz wafer 2 both sides, lead-in wire 4 and the conducting resinl 5 for being communicated with described metal electrode 3 and affiliated lead-in wire 4, and described conducting resinl 5 is positioned at the corner place of described quartz wafer 2.
The utility model also comprises the electrode ear 6 be connected with described metal electrode 3, and described electrode ear 6 is extended to the corner place of described quartz wafer 2 and is connected with described lead-in wire 4 by described conducting resinl 5.
Described electrode ear 6 is in Y type, and described electrode ear 6 one end of Y type is connected with described metal electrode 3, and two ends extend to the Liang Jiaochu of described quartz wafer 2 in addition.
The bonding area of described conducting resinl 5 is no more than the half of described electrode ear 6 area.
The utility model can make the more former technique reduction of the resistance of product 20%, DLD then reduce 15%, and the change of some plastic structure, improves crystal vibration vigor, reduces resistance; Overcoming the problem of in the past sacrificing intermediate frequency crystal anti-drop for reducing resistance, having positive meaning to the supporting of current handheld mobile device.
The utility model is applied to the technical field of quartz-crystal resonator.
Although embodiment of the present utility model describes with practical solution, but the restriction do not formed the utility model implication, for those skilled in the art, according to this specification to the amendment of its embodiment and and the combination of other schemes be all apparent.
