The surface layout of the quartz crystal has the coat of metal.
Flat ceramic body and base of ceramic pass through metal solder layer between the two and carry out heating engagement.Metal solder layer at
Divide including but not limited to tin silver copper scolding tin or silver.
The length and width dimensions of base of ceramic are necessarily less than the length and width dimensions of flat ceramic body.
Flat ceramic body is made using CET toughening oxide ceramic, and centre is provided with oblong openings for accommodating
The thermistor.
The volume of quartz-crystal resonator be 1.2x1.0x0.50mm, 1.6x1.2x0.56mm 2.0x1.6x0.60mm,
2.5x2.0x0.90mm。
The utility model has the advantages that the utility model relates to a kind of thermo-responsive resonator of multi-layer ceramics metal sintering, Neng Gouke
Have to pass through the technical bottleneck of high temperature sintering when taking the processing of original H-type ceramic structure, at the same by quartz-crystal resonator layer and
The different sizes of thermistor cavity layer design, and reduce the stress that each layer ceramics generate in encapsulation process, are promoted small-sized
Change the output frequency precision of thermo-responsive quartz-crystal resonator.
