Abstract
The utility model discloses a quartz crystal resonator with nickel silver electrodes. The quartz crystal resonator with the nickel silver electrodes comprises a quartz wafer, 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 a front face electrode lead wire connected with the front face electrode. The back face of the quartz crystal is provided with a back face electrode lead wire connected with the back face electrode. All of the front face electrode, the front face electrode lead wire, the back face electrode, and the back face electrode lead wire are double-layer structures. An inner layer of the double-layer structure is a nickel coating, and an outer layer of the double-layer structure is a silver coating. The quartz crystal resonator with the nickel silver electrodes is firmer and more reliable.
Description
Technical field
The utility model relates to a kind of quartz-crystal resonator with nickeline 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.
Electrode on the core component quartz wafer of quartz-crystal resonator is considered production efficiency and processing cost traditionally, and is general simple silver-plated, has hidden danger aspect firmness and the quartz-crystal resonator resistance and high temperature resistance property of electrodes on wafer.
The utility model content
The utility model technical problem to be solved provides a kind of quartz-crystal resonator with nickeline electrode, more firm, the good reliability of this quartz-crystal resonator with nickeline electrode.
The technical solution of utility model is following:
A kind of quartz-crystal resonator with nickeline electrode; Comprise quartz wafer, front electrode and backplate; Front electrode and backplate are separately positioned on the front and back of quartz crystal, are provided with the front electrode lead-in wire that links to each other with front electrode in the front of quartz crystal; Be provided with the backplate lead-in wire that links to each other with backplate at the back side of quartz crystal; Front electrode, front electrode lead-in wire, backplate and backplate lead-in wire are double-decker; Described double-deck internal layer is a nickel coating, and double-deck skin is a silver coating.
Beneficial effect:
The quartz-crystal resonator with nickeline electrode of the utility model; Its front electrode, front electrode lead-in wire, backplate and backplate lead-in wire all adopt double-decker; Double-deck internal layer is a nickel coating, and double-deck skin is a silver coating, has strengthened the firmness of electrode; And make the quartz-crystal resonator resistance to elevated temperatures strengthen, finally make quartz-crystal resonator more reliably, more stable.
