Abstract
SMT mounts quartz-crystal resonator, base of ceramic top is fixed with metal top cover by fluid sealant, base of ceramic intracavity bottom is provided with two positioning boss, and quartz wafer two ends are fixedly mounted on positioning boss by conducting resinl, and the upper and lower surface of quartz wafer is equipped with silver electrode; The top of two positioning boss all scribbles prints electrode, and two are printed electrode by being connected with pin C with the pin A bottom base of ceramic respectively around tape; Pin B bottom base of ceramic is connected by pin line with pin D, and pin B is all connected with solder(ing) paste by upper cover line with pin D, and the top of solder(ing) paste is connected with one end edge of metal top cover.The utility model advantage has: 1. fluid sealant connects the material internal stress and consequent frequency drift eliminating and discharge and melt and connect and cause.2. by blocking type ground wire, pin is split, suppress spurious clutter signal, eliminate electrostatic buildup.3. reduce the material cost of base of ceramic, enhance productivity.
Description
Technical field
The utility model relates to quartz crystal production technical field, and specifically a kind of SMT mounts quartz-crystal resonator.
Background technology
Quartz-crystal resonator is the resonant element utilizing the inverse piezoelectric effect characteristic of quartz crystal and make, and itself and semiconductor chip, together with resistance capacitance element, constitute oscillating circuit signal source of clock.Along with electronic product is intelligent, microminiature modularized design, current general small-size quartz-crystal resonator is difficult to more greatly satisfy the demands because of volume, and there is following shortcoming: 1. sealing must be the mode of electric resistance welding or the weldering of electric current seam, and equipment cost is high, needs processing precise, requires harshness; 2. before and after sealing, frequency change is large, and communication and transmission precision reduce.
Utility model content
For the deficiency that above-mentioned similar technique problem exists, the purpose of this utility model is to provide a kind of SMT and mounts quartz-crystal resonator.
The technical solution of the utility model is: SMT mounts quartz-crystal resonator, comprise base of ceramic, metal top cover, quartz wafer, it is characterized in that: base of ceramic top is fixed with metal top cover by fluid sealant, base of ceramic intracavity bottom is provided with two positioning boss, quartz wafer two ends are fixedly mounted on positioning boss by conducting resinl, and the upper and lower surface of quartz wafer is equipped with silver electrode; The top of two positioning boss all scribbles prints electrode, and two are printed electrode by being connected with pin C with the pin A bottom base of ceramic respectively around tape; Pin B bottom base of ceramic is connected by pin line with pin D, and pin B is all connected with solder(ing) paste by upper cover line with pin D, the top of solder(ing) paste is connected with one end edge of metal top cover, and described upper cover line and solder(ing) paste brushing are on the seamed edge of base of ceramic.
The utility model has the advantages that: adopt fluid sealant to be connected with base of ceramic by metal top cover, be different from the connected mode of traditional electric discharge fusing.The ground wire pin B be connected between pin A and pin C and pin D blocks.Solder(ing) paste is painted between metal top cover and base of ceramic ground wire pin, and metal top cover is communicated with the ground wire pin of base of ceramic.Its advantage has: 1. fluid sealant connects the material internal stress and consequent frequency drift eliminating and discharge and melt and connect and cause.2. by blocking type ground wire, pin is split, suppress spurious clutter signal, eliminate electrostatic buildup.3. reduce the material cost of base of ceramic, enhance productivity, strengthen product competitiveness.
