Abstract
The utility model discloses a quartz crystal resonator with two electrodes. The quartz crystal resonator with two electrodes comprises a quartz wafer and a main electrode. The main electrode comprises a front face electrode and a back face electrode. The front face electrode and the back face electrode are respectively arranged on a front face and a back face of a quartz crystal. The front face of the quartz crystal is provided with an upper and a lower front face electrode lead wires connected with the front face electrode. The back face of the quartz crystal is provided with an upper and a lower back face electrode lead wires connected with the back face electrode. Both the front face electrode lead wires and the back face electrode lead wires are fold belt-shaped lead wires. The two front face electrode lead wires are symmetrical about the center point of the quartz wafer. The two back face electrode lead wires are symmetrical about the center point of the quartz wafer. The lead wires of the quartz crystal resonator with two electrodes use the upper and lower symmetry design, avoid the direction identification in sheet loading, and are in favor of improving the production efficiency.
Description
Technical field
The utility model relates to a kind of quartz-crystal resonator with bipolar electrode.
Background technology
Quartz-crystal resonator mainly is made up of pedestal, quartz wafer, shell; 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.
Tradition cylindrulite electrode design is as shown in Figure 2, is on quartz wafer, to design main electrode, at the end design backplate lead-in wire and the front electrode lead-in wire of quartz wafer, need discern direction in the time of last slice again, and efficient is low.
The utility model content
The utility model technical problem to be solved provides a kind of quartz-crystal resonator with bipolar electrode; This contact conductor with quartz-crystal resonator of bipolar electrode adopts symmetric design up and down; Avoid the direction identification last slice the time, and helped promoting production efficiency.
The technical solution of utility model is following:
A kind of quartz-crystal resonator with bipolar electrode; Comprise quartz wafer and main electrode; Main electrode is made up of front electrode and backplate; Front electrode and backplate are separately positioned on the front and back of quartz crystal, are provided with upper and lower two front electrode lead-in wires that link to each other with front electrode in the front of quartz crystal; Be provided with upper and lower two backplate lead-in wires that link to each other with backplate at the back side of quartz crystal.
Described front electrode lead-in wire and backplate lead-in wire are folding band shape lead-in wire.
Article two, the front electrode lead-in wire is about the quartz wafer central point; Article two, the backplate lead-in wire is about the quartz wafer central point; The front electrode lead-in wire of upside and the backplate lead-in wire of downside are located at the left side of quartz wafer; The backplate lead-in wire of upside and the front electrode lead-in wire of downside are located at the right side of quartz wafer.
Beneficial effect:
The quartz-crystal resonator with bipolar electrode of the utility model; Contact conductor adopts symmetric design (promptly all contact conductors are all about the central point of wafer); Avoided the direction identification last slice the time; Help promoting production efficiency, and strengthened the balance of crystal vibration, all beneficial to suppressing parasitism, coupling etc.
