Description
Technical field
The utility model is related to technical field of electronic components, especially a kind of to be produced for SMD plastic-packaged electronic components
Three-dimensional continuous metal strip.
Background technology
It is traditional plug-in type that the big portion of extraordinary electronic component produced at present, which takes,：It is welded simultaneously by silver core piece two sides
Upper elongated garden lead encapsulates one layer of insulating materials in silver-colored face chip surface, which is epoxy resin, silicones, phenol
One kind in urea formaldehyde, product use artificial plug-in method using installation, partly take braid plug-in unit, also made because pin pitch is easily deformed
Into a large amount of defective products, plug-in method overwhelming majority postwelding is vertical on pcb board, occupied space.
Product miniaturization, thin type, patch type are irreversible development trends, and plug-in type product is changed to surface mount
Irresistible trend, at present low pressure low value capacitor, the piezoresistor of low pressure low current amount, temperature control PTC/
NTC all using chip production technology, and the piezoresistor of the big flux of high-voltage large-capacity capacitor, high pressure, big through-flow PTC,
Inhibit the NTC of surge using still plug-in type production.
ZL201620681451.0 mentions a kind of element pasted on surface, and this structure has disadvantage mentioned above：1) volume is big, accounts for
Area is big；2) because that, because of reasons such as molding, sintering curres, chip thickness thickness can be caused to differ, it is difficult to make in tile production process
3 points all in a level, seriously affect welding performance.
ZL2015207476269.4 mentions a kind of element pasted on surface, is that existing plug-in unit product is packed into an insulation crust
In, this volume becomes much larger, and cost is also very high, therefore is difficult to promote.
ZL200310117543.3 mentions a kind of method of manufacturing technology of sheets type ceramic dielectric capacitor, has the disadvantage that：
1) two metal tapes, plug-in unit and location difficulty are needed：It needs to do many frock clamps, and can only press from both sides per sleeve clamp
A limited number of several to more than ten products；
2) welding difficulty：It needs, on chip two sides and upper and lower side body lead coating soldering paste, to press from both sides in Special tooling clamp
Baking box or oven baking welding after fixing are held, working efficiency is poor, and failure welding product are more；
3) production technology of 10 every or so products is actually used in process of production, and it is more to have enough to meet the need needs in production process
Otherwise limited bracket is easily deformed, turnover and volume production are all had any problem.
4) temperature is very high when toasting, therefore not tin plating metal tape can only be used to produce, re-plating tin after plastic packaging, and technique is multiple
It is miscellaneous, it is of high cost.
Utility model content
The purpose of this utility model is：A kind of three-dimensional continuous metal strip for the production of SMD plastic-packaged electronic components is provided,
Its compact, is suitable for continuous production, and the properties of product for producing acquisition are reliable and stable, and it is efficient to come into force, at low cost
It is honest and clean.
The utility model is realized in this way：For SMD plastic-packaged electronic components production three-dimensional continuous metal strip, including
Two disjunctor items, two disjunctor items are mutually parallel, and are connected by connection strap normal thereto, connect from a wherein disjunctor item
Connect exit, the end of upper exit connect upper end, on another disjunctor item connection on connect under exit and,
Lower exit end connection lower end, between upper end and lower end there are for place by the gap of silver-colored tile.
Location hole is equipped on the disjunctor item.
As a result of above technical scheme, the utility model has the advantage that:
Using a disjunctor stereo metal band scheme, solve the problems, such as orientation problem, automated production, turnover, avoid mistake
The quality problems such as position, turnover deformation, do not need to positioning tool and revolving bracket, simplify production procedure, connect high efficiency significantly.
The utility model is simple in structure, of low cost, and using effect is good.

Specific embodiment
The embodiment of the utility model：For the three-dimensional continuous metal strip of SMD plastic-packaged electronic components production, including two
Disjunctor item 27, two disjunctor items 27 are mutually parallel, and are connected by connection strap 26 normal thereto, from a wherein disjunctor item 27
Exit 22 in upper connection connects upper end 21 in the end of upper exit 22, is connected in connection on another disjunctor item 27
Lower exit 24 and, connect lower end 23 in the end of lower exit 24, there are for putting between upper end 21 and lower end 23
It puts by the gap of silver-colored tile 10；Location hole 25 is equipped on the disjunctor item 27.
The embodiment described in the utility model being not limited to described in specific embodiment, those skilled in the art are according to this
The technical solution of utility model obtains other embodiments, also belongs to the technological innovation scope of the utility model.Obviously originally
The technical staff in field can carry out the utility model spirit and model of the various modification and variations without departing from the utility model
It encloses.In this way, if these modifications and variations of the present invention belong to the claims of the present invention and its equivalent technology range
Interior, then the utility model is also intended to include these modifications and variations.
