Abstract
The utility model relates to a quartz crystal oscillator with electrodes on a same face, and belongs to the technical field of electronic elements. The quartz crystal oscillator with electrodes on the same face comprises a quartz crystal body and electrodes on the surface of a quartz crystal piece. The quartz crystal oscillator is characterized in that the two electrodes are arranged on the same face of the quartz crystal piece. One of the quartz electrodes located in the center of the face is circular and extends to form a lead toward the edge. The other one of the quartz electrodes, which is opened and circular, surrounds the periphery of the electrode and extends to form a lead toward the edge. The two electrodes are electrically insulated. The electrodes are made of excellent conductive materials. According to the quartz crystal oscillator provided by the utility model, the manufacturing process is simplified, the detection sensitivity is improved, and the quartz crystal oscillator is agile and convenient to use.
Description
Technical field
The utility model relates to a kind of electrode and is positioned at quartz-crystal unit simultaneously, belongs to technical field of electronic components.Be used for quartz oscillator and quartz crystal microbalance sensor etc.
Background technology
Quartz-crystal unit can be used as the transducer that detects micro substance, the principle of utilizing the frequency change of quartz-crystal unit to be directly proportional with the mass change of plane of crystal, but the mass change of detecting electrode surface n g level and the viscosity of solution, density, the isoparametric variation of modified membrane viscoplasticity, have highly sensitive, characteristics such as can measure in real time, can be used as the means that on-line tracing monitoring microprocess changes, at modern chemistry, material science, the exploratory development of the microprocess and the mechanism of action is carried out in aspect such as biology and medical science, presents bright development prospect in a lot of applications.The core component of quartz oscillator is a quartz-crystal unit, and it comprises the coatings on quartz crystal slice body and quartz crystal slice surface, and coatings is generally good electric conductor, with as electrode.Usually, be separately positioned on the two sides of quartz crystal slice as the coatings of electrode, when powering up with thickness tangential manner excited oscillation.U.S. Pat 7075216B1 discloses a kind of " side field excitation sonic sensor " (Lateral field excited acoustic wave sensor) is characterized in that being coated with on the quartz crystal slice surface two semicircle metal films with symmetry as electrode, this design starting vibration difficulty, have the one side of electrode to be difficult for, and sensitivity is lower as testing face.
The utility model content
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of electrode to be positioned at quartz-crystal unit simultaneously, can simplify manufacture craft, improves detection sensitivity, and is flexible and convenient to use.
For realizing above-mentioned technical purpose, the utility model is taked following technical scheme: a kind of electrode is positioned at the quartz-crystal unit with one side, the electrode that comprises quartz crystal slice body and quartz crystal slice surface, it is characterized in that, its two electrodes are arranged on the same one side of quartz crystal slice, one of them electrode is positioned at the center of this face, stretch out lead-in wire for circle and to the edge, another electrode be open annular be surrounded on former electrodes around and stretch out lead-in wire to the edge, two electrode electric insulations, described electrode is a material with good electric conductor.The electrodeless one side of quartz crystal oscillator sheet, can make as required becomes different testing faces.
The beneficial effects of the utility model are that the pair of electrodes plate of quartz-crystal unit is arranged on the same side of crystal, can disposablely finish coating single side during manufacturing, does not need double-sided coating, has simplified manufacture craft.Its back side is as the testing face of transducer, can select different plated films as required or carry out special surface preparation, and the resonant circuit electrode separates with the testing face electricity of transducer, has got rid of the influence to the resonant circuit electrode when other purposes of this electrode.The set-up mode of this kind electrode makes the mass sensitivity of the testing face of transducer improve 1-2 times, and makes the application of quartz-crystal unit more wide.
