The resonator comprises a base and a chip arranged on the base, wherein the front side of the chip is provided with a front side electrode, a front side electrode lead and a front side auxiliary electrode; the front side electrode is connected with the front side auxiliary electrode through the front side electrode lead; the front side electrode lead and the front side auxiliary electrode are arranged on the right side of the chip; the back side of the chip is provided with a back side electrode, a back side electrode lead and a back side auxiliary electrode; the back side electrode is connected with the back side auxiliary electrode though the back side electrode lead; the back side electrode lead and the back side auxiliary electrode are arranged on the left side of the chip; the front side electrode lead is arranged in the center of the side of the front side electrode; and the back side electrode lead is arranged in the center of the side of the back side electrode. By the resonator of the SMD, the chip and the base are combined firmly, and the reliability is strengthened.
Description
Technical field
The utility model relates to a kind of SMD resonator.
Background technology
The SMD resonator mainly is made up of pedestal and quartz wafer; Be widely used in communication system, supervisory control system, warning system aspect in telecommunications such as intercom, PDA, mobile phone, radio telephone, VCD, DVD, computer, TV, satellite, automobile audio, vehicle radio station, automobile burglar, digital product, remote control system and the electron trade; It is one of core component of these products; Image is likened human heart to, and importance is only second to IC.SMD refers to the abbreviation of Surface Mounted Devices, means: surface mount device.
Existing SMD resonator, structure is as shown in Figure 2, and each electrode only has a contact conductor, and poor stability is unfavorable for that also wafer is fixed on the pedestal.
The utility model content
The utility model technical problem to be solved provides a kind of SMD resonator, and wafer in this SMD resonator and pedestal combine more firm, good reliability.
The technical solution of utility model is following:
A kind of SMD resonator comprises pedestal and is arranged on the wafer on the pedestal; The front of wafer is provided with front electrode, front electrode lead-in wire and front auxiliary electrode, and front electrode is connected with the front auxiliary electrode through the front electrode lead-in wire, and front electrode lead-in wire and front auxiliary electrode all are arranged on the right-hand of wafer;
The back side of wafer is provided with backplate, backplate lead-in wire and back side auxiliary electrode; Backplate is connected with back side auxiliary electrode through the backplate lead-in wire, and backplate lead-in wire and back side auxiliary electrode all are arranged on the left of wafer.
The front electrode lead-in wire is arranged on the place, center of front electrode sidepiece; The backplate lead-in wire is arranged on the place, center of backplate sidepiece.
Beneficial effect:
The SMD resonator of the utility model, owing to one in front electrode lead-in wire, one of front auxiliary electrode and one in backplate lead-in wire, one of back side auxiliary electrode, and branch is located at relative both sides; Therefore; Electrical property is more balanced, and contact conductor and auxiliary electrode be in and be convenient to be provided with the glue application region territory, thereby all there is the strong point left and right sides of wafer; Anti-dropping capability strengthens, finally make the SMD resonator more reliably, more stable.
Description of drawings
Fig. 1 is the structural representation of the SMD resonator of the utility model;
Fig. 2 is the structural representation of existing SMD resonator;
Label declaration: 1-pedestal, 2-backplate lead-in wire, 3-wafer, 4-front electrode, 5-front electrode lead-in wire, 6-glue application region territory, 7-back side auxiliary electrode, 8-front auxiliary electrode.
Embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is explained further details:
Embodiment 1:
As shown in Figure 1, a kind of SMD resonator comprises pedestal and is arranged on the wafer on the pedestal; The front of wafer is provided with front electrode, front electrode lead-in wire and front auxiliary electrode, and front electrode is connected with the front auxiliary electrode through the front electrode lead-in wire, and front electrode lead-in wire and front auxiliary electrode all are arranged on the right-hand of wafer;
The back side of wafer is provided with backplate, backplate lead-in wire and back side auxiliary electrode; Backplate is connected with back side auxiliary electrode through the backplate lead-in wire, and backplate lead-in wire and back side auxiliary electrode all are arranged on the left of wafer.
The front electrode lead-in wire is arranged on the place, center of front electrode sidepiece; The backplate lead-in wire is arranged on the place, center of backplate sidepiece.
Because one in front electrode lead-in wire, one of front auxiliary electrode and one in backplate lead-in wire, one of back side auxiliary electrode; And divide and to be located at relative both sides, therefore 2 contact conductors and auxiliary electrode can be provided with 4 glue application region territories, some glue and colloid solidified after; All there is adhesive spots (being the strong point) left and right sides of wafer on pedestal; Only have the strong point and be different from existing SMD resonator in a side, thereby the anti-dropping capability enhancing, reliability also can significantly improve.
