Specific embodiment
In order to which the technical problems to be solved in the utility model, technical solution and beneficial effect is more clearly understood, below
In conjunction with the embodiments, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to
It explains the present invention, is not intended to limit the present invention.
The utility model embodiment provides a kind of quartz resonator of base of ceramic.The surface mount stone
Picture 1-4, the quartz resonator 10 includes base of ceramic 20, Quartz crystal resonant piece to the structure of English resonator
30, metal lid or ceramic outer cover 40.
Wherein, the base of ceramic 20 is plate, and there are four metal binding disks 21,22,23,24 such as Fig. 2 for upper surface
Shown, lower surface (back side that is to say the upper surface) there are four metal pads 25,26,27,28 as shown in Figure 4；One gold
Belonging to binding disk 21 and a metal pad 25 has electrical connection, another metal binding disk 22 and another metal pad
26 have electrical connection, and 23,24,27,28 settings are for the intensity of balanced entire plate.Itself do not play the role of connection, wherein
21 and 23,22 and 24,25 and 27,26 and 28 can be described in detail wherein an example at this, not had and limit this hair with exchange function
Bright effect.
The specific base of ceramic is with a thickness of 0.10-0.60mm.Thickness appropriate ensure that intensity, and take into account product
Slimming requires.Then intensity is inadequate for thickness low LCL, can not effective protection electronic component internal structure, it is too thick to will limit final production
The slimming of product/module.
The dielectric constant of the specific base of ceramic is 8.0-10.0.Quartz crystal resonator base, dielectric constant are low
The direct capacitance of resonator can be made to maintain reduced levels, guarantee the stability of oscillating circuit.
The thermal expansion coefficient of the specific base of ceramic is 4.0-9.0x10-6/K.As quartz crystal resonator base,
Heat expansion coefficient of expansion is consistent or close with quartz vibrator, can lower and avoid quartz resonator in different temperatures, because of different materials
Between expansion variable it is different caused by structural stress variation influence electrical property.
Respectively there are a metal electrode 31, electrode 32 in 30 two faces of the Quartz crystal resonant piece, such as Fig. 2 and Fig. 4, the resonance
Piece 30 is fixed at least two metal binding disks 21,22 of base of ceramic 20 by conductive adhesion object 50, while resonance
Each metal electrode 31,32 on 30 two faces of piece is bonded with two metals of base of ceramic 20 respectively by conductive adhesion object 50
Object disk 21,22 has mechanical connection and electrical connection, to be electrically connected respectively with two metal pads 25,26 on base of ceramic 20
It connects.
The structure of the metal lid 40 is as shown in Figure 2 and Figure 4, is concave 41 among the metal lid 40, so as to energy
Whole metal binding disks 21,22 of Quartz crystal resonant piece 30 and base of ceramic 20 are enough covered, while not contacting quartz again
Any metal binding disk 21,22 on crystal resonant piece 30 and base of ceramic 20.
The marginal portion 42 of the metal lid and ceramic outer cover 40 can pass through capping binding 60 and base of ceramic 20
Marginal portion 29 carry out bonding connection, entire Quartz crystal resonant piece 30 is sealed in by base of ceramic 20 and having recess portion 41
Metal lid 40 is formed by space.
Traditional multi-layered ceramic pedestal is substituted with base of ceramic for the quartz resonator, and the base of ceramic is to adopt
With integrally formed, therefore preparation step is enormously simplified, saved cost, is suitble to large-scale production demand.
