Abstract
The present invention discloses a kind of SMD quartz crystal resonator pedestal, using the printed substrate fabrication techniques that the application of epoxy resin double face copper is ripe, electrode and pad are made with the mode of etching, electrode is connected with pad by cable-through hole, finally to electrode and the naked copper plating nickel gold of pad.Compared with prior art, quartz crystal resonator base of the invention, 49S/SMD series and SMD base of ceramic series in the market can be substituted in structure completely, meets quartz-crystal resonator low cost, the requirement of miniaturization；While very good effect is attained by terms of conductive, insulation, support, solve the problems, such as original structure complex manufacturing, high processing costs, directly reduce material cost, product can substitute most quartz crystal resonator base in the market after releasing, and have broad application prospects.
Description
Technical field
The invention belongs to quartz-crystal resonator technical field of structures, and in particular to a kind of quartz crystal resonator base.
Background technology
At present, the base construction of quartz-crystal resonator has two kinds：
It is that first metal substrate, glass dust, metal lead wire are burnt through high temperature first, such as the inserter structure of 49S, 49U series
Form an entirety, then in lead upper end spot welding metal clips, form complete pedestal；The construction pedestals are processed into quartz-crystal
The production procedure of body resonator is：By silver → dispensing → fine setting → soldering and sealing → airtight inspection → aging → test → marking note → bag
Dress → delivery.For the requirement of adaptation terminal client automate production processes, the quartz-crystal resonator that the construction pedestals are processed into,
It is processed further being fabricated to 49S/SMD types, in the process of 49S/SMD shapings, lead is passed through into insulation spacer, is molded with SMD
Equipment, lead is processed into surface mount formats.The shortcomings that construction pedestals is that production automation degree is low, and process is more, production
Efficiency is low, and power consumption is high.
Second, the surface attaching type structure such as SMD series：It is that sintering can cut down material metal ring and form on ceramic substrate.The knot
The production procedure that structure pedestal is processed into quartz-crystal resonator is：By silver → dispensing → fine setting → soldering and sealing → airtight inspection → aging
→ test → marking note → packaging → delivery, the process of fewer than 49S/SMD types SMD shapings.But still suffer from shortcoming：Should
The pedestal of structure will substantially rely on external import, quartz-crystal resonator production equipment also most of external import, be produced into
This height.
The content of the invention
It is an object of the invention to using the base material different from above two structure, be processed into a kind of brand-new quartz crystal
Resonator base, material cost is directly reduced, design advantages of simple, easy processing, cost is low, in terms of conductive, insulation, support all
Very good effect can be reached.
Technical scheme disclosed by the invention is as follows：
A kind of SMD quartz crystal resonator pedestal, is made as follows：
1. the two sides of epoxy resin base plate covers copper coin respectively；
2. etching electrode in the one side of the substrate using PCB technology, another side etches pad；
3. open up more than one insertion in the position that the electrode and projection of the pad on epoxy resin base plate coincide
The cable-through hole of the electrode, epoxy resin base plate and pad；
4. metal material is irrigated in the cable-through hole and closing cable-through hole makes the electrode be turned on the pad；
5. in the plating nickel on surface of the electrode and pad gold.
Further, step 5. in, also to the exposed perfusion cable-through hole metal material surface plating nickel gold.
Compared with prior art, quartz crystal resonator base of the invention, existing market can be substituted completely in structure
On 49S/SMD series and SMD base of ceramic series, meet quartz-crystal resonator low cost, miniaturization requirement；Leading
While being attained by very good effect in terms of electricity, insulation, support, solve original structure complex manufacturing, high processing costs
The problem of, material cost is directly reduced, product can substitute most quartz-crystal resonator in the market after releasing
Pedestal, have broad application prospects.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation at another visual angle of the present invention.
Embodiment
Referring to accompanying drawing, a kind of SMD quartz crystal resonator pedestal, it is made as follows：
1. the two sides of epoxy resin base plate 1 covers copper coin respectively；
2. etching electrode 2 in the one side of the substrate 1 using PCB technology, another side etches pad 3；
3. 2 insertion electricity are opened up in the position that the electrode and projection of the pad on epoxy resin base plate coincide
The cable-through hole 4 of pole 2, epoxy resin base plate 1 and pad 3；
4. metal material is irrigated in the cable-through hole 4 and closing cable-through hole makes the electrode 2 be turned on the pad 3；
5. in the electrode 2, the pad 3 and the exposed perfusion cable-through hole metal material surface plating nickel gold
Plating nickel on surface gold.
The quartz crystal resonator base of the present invention, 49S/SMD series in the market can be substituted in structure completely
With SMD base of ceramic series, quartz-crystal resonator low cost, the requirement of miniaturization are met；In conductive, insulation, support side
While face is attained by very good effect, solve the problems, such as original structure complex manufacturing, high processing costs, directly reduce
Material cost, product can substitute most quartz crystal resonator base in the market after releasing, and have wide
Application prospect.
