Description
Technical field
The utility model is related to electrical resonator, more particularly to a kind of SMD quartz resonators and its process equipment.
Background technology
SMD quartz crystal resonator is conventional electronic device, and with the development of digitizing technique, its consumption increasingly increases.
But current SMD quartz crystal resonator is existed in raising processing efficiency, drop with terms of processing technology in itself from device architecture
Technology barrier in terms of low production cost.
The SMD quartz crystal resonator structure of prior art is as shown in figure 1, be first by printing on base of ceramic 1
Nickel plating and gold form the coat of metal 3 to tungsten metal level again, and then sinter attached yellow gold thereon in high temperature reducing atmospheres can
Ring is cut down, metal cover board 2 is finally covered on the cut down ring of attached yellow gold, by parallel soldering and sealing, by rolled metal cover plate side
Be packaged together for metal cover board and base of ceramic by edge.The cut down ring of the attached yellow gold is that can cut down (the iron-cobalt-nickel of material 16
Alloy：Hot pressing yellow gold layer 17 on 4J29), yellow gold therein occupies sizable ratio in quartz resonator totle drilling cost
Example, so if the cut down ring that can save attached yellow gold will substantially reduce product cost.
But the cut down ring of attached yellow gold is still difficult to omit in the prior art, and its reason is, in SMD quartz resonators
In product standard, in order to the performance for ensureing resonator is distinctly claimed to the parameter of metal cover board, such as anti-substrate bendability,
Firmness, monomer intensity etc., therefore metal cover board will possess certain thickness to ensure its mechanical performance, usual metal cover board
Thickness is 0.05mm-0.08mm, during soldering and sealing, due to needing relatively thicker metal cover board and the base of ceramic melting welding
Together, it is therefore desirable to have enough welding energies.For high power welding energy, it is difficult to control its depth of interaction just to complete weldering
Connect without damaging ceramic layer, be the thermal expansion system that can cut down material the reason for selection can cut down material so needing that the protection of ring can be cut down
Number is approached with ceramics, and stress is small during welding；The effect that selection can cut down the attached yellow gold of material is that silver-copper brazing alloy fusing point is low, can be dropped
Low welding energy.Therefore, ring can be cut down actually served during welding metal cover plate and protect base of ceramic frame not burnt
The effect split.But this not only makes SMD quartz resonator complex structures, manufacturing procedure increases, and relatively costly.
If its edge throat thickness can be reduced under the premise of the every mechanical performance for ensureing metal cover board, it is possible to adopt
It is easy to the welding energy of control with less, so as to be also avoided that in welding to pottery without the ring protection cut down of attached yellow gold
The damage of porcelain pedestal frame, so save can cut down ring including yellow gold layer, substantially reduce production and product cost.
Said from processing technology, current SMD quartz crystal resonator uses parallel sealing technique, parallel sealing technique to be a weld through
A kind of differentiation of technology, applies in SMD quartz crystal resonator encapsulation that there are the following problems：1st, require by welding metal material
Thickness is in 0.1~0.25mm, it is difficult to reduce material cost；Electrode wheel contacts adjacent welding thing when the 2nd, in order to avoid welding, needs
Wanting welded article to arrange ranks has larger spacing, influences production efficiency and equipment size, such as one processing supporting plate of B4 paper sizes
It is only capable of carrying 300 or so parts, this causes each manufacturing procedure machine huge；3rd, easily there is viscous damage and make weldering in roll welding electrode surface
Seam surface quality degenerates, it is necessary to timing finishing electrode, influences maintenance cost；4th, must be positioned using spot welding, influence welding efficiency；
5th, point solid point needs suitable spacing, i.e., have size to require welded article, influences applicability.Therefore production cost is caused to occupy height not
Under.
