Method for trimming provided in an embodiment of the present invention is illustrated in detail below:
Aiming at the problem that background technique refers to, the embodiment of the present invention proposes a kind of quartz-crystal resonator and oscillator
The whole method of frequency trim.This method is simple, easily operated, at low cost and can produce in enormous quantities, and specific steps include:
A, it selects product: the package casing of quartz-crystal resonator or oscillator is selected, so that laser frequency is micro-
The electromagnetic beam that tune machine 102 generates can pass through, and the frequency of these selected products is all above the product of specification.
B, upper product: the quartz-crystal resonator chosen or oscillator are put into fine tuning frock clamp, then will fine tuning
Frock clamp is put into laser frequency freqency fine adjustment machine.Specific requirement in this step is that fine tuning frock clamp is being put into laser frequency
In rate freqency fine adjustment machine, guarantee the outer cover of quartz-crystal resonator or oscillator to be fine tuned fixed on fine tuning frock clamp to
On, so that electromagnetic beam carries out the micro- of frequency by reaching the quartz wafer of the quartz-crystal resonator or oscillator after outer cover
Adjustment.
C, finely tune frequency: starting laser frequency freqency fine adjustment machine starts the micro-adjustment that frequency is carried out to each product.In this process
In, the frequency for the product being trimmed off can slowly rise, and the real-time detection the phenomenon that rising of this frequency by frequency tester.
When frequency rises within specification, frequency tester can issue signal, stop laser frequency freqency fine adjustment machine and continue to finely tune this production
Product.Then, mobile fine tuning tooling, makes another product enter fine tuning area, starts to finely tune another product, until entire work
Product in dress is fine-tuning in defined frequency range.
D, the product after being trimmed off lower product: is taken out into laser trimming machine.
Specifically, in embodiments of the present invention, it is carried out firstly, for the package casing of quartz-crystal resonator or oscillator
Selection, so that electromagnetic beam can pass through.Although in practice, the shell of quartz-crystal resonator or oscillator can be by any suitable

Very effective, physical characteristic can be such that electromagnetic beam passes through.
Secondly, how to determine the energy carrier of fine tuning -- electromagnetic beam is the emphasis of the embodiment of the present invention.Although electromagnetic wave
Any suitable electromagnetic beam, such as general visible beam can be selected in beam, but preferably electromagnetic beam or laser beam,
In the present embodiment, it is easy to based on laser beam through quartz crystal, and the physical characteristic that laser beam energy is concentrated very much,
In the embodiment of the present invention, the electromagnetic beam that laser frequency freqency fine adjustment machine generates is laser beam.
After product to be fine tuned is put into laser trimming machine, the laser beam with specific frequency is in the stone for passing through the product
After English crystal shell, energy loss very little.When the laser beam for having enough energy reaches quartz crystal slice (also referred to as crystal resonant
Piece) on when, this energy can remove the metal electrode (such as silver electrode) on Partial wafer immediately, subtract the effective thickness of resonance piece
It is few, so that the effective frequency of resonance piece be made to increase, achieve the purpose that frequency adjusts.
In the thickness shear oscillation mode of quartz crystal, the resonance frequency of resonance piece and the thickness of resonance piece have following public affairs
Formula:
F=1.67/t；
In above-mentioned formula, t indicates that thickness, unit mm, F indicate that resonance frequency, unit MHz, this resonance frequency are led to
Often between 1MHz~200MHz.
In practice, resonance piece has two electrodes up and down, to apply external alternating voltage.It is humorous in specifically used
Vibration piece resonance requires in frequency in a frequency in response to external alternating voltage is related.
