Description
Technical field
The utility model is related to engineering goods field, more particularly to a kind of corrosion-resistant solder horn.
Background technology
With the development of economy era, electronic technology and electronic component occupy more and more important ground in society
Position, wherein solder horn are just particularly significant in the process of electronic product.
Existing solder horn is in process mainly by the way of the outer plating iron of copper, that is, in existing copper embryo outer layer
Iron layer is electroplated, such mode can have following defect：
1st, substantial amounts of hole and bubble can be produced in iron layer in electroplating process, the size and location of these holes and bubble
All it is random distribution in iron layer.When solder horn is in scolding tin, tin liquor can constantly corrode electricity with normal speed at high temperature
Plate iron layer, but when high temperature tin liquor encounter plating in hole and bubble when, high temperature tin liquor can be accelerated by hole or bubble to
Iron layer internal corrosion is electroplated, so as to substantially reduce the service life of solder horn；Meanwhile, the size and location of hole and bubble is in iron
All it is random distribution in layer, causes the solder horn life-span produced different in size；
2nd, electroplate liquid high-temperature steam can seriously volatilize in existing electroplating technology, be detrimental to health；And can discharge big
The electroplating sewerage of amount, causes environmental pollution；
3rd, existing solder horn production technology will be by techniques, whole flow process such as cutting copper embryo, the polishing of copper embryo, cleaning, plating iron
The cost time, its production cycle was long more than 480 minutes, and Expenses Cost is high；Adding what man-hour requirement artificially judged to come not simultaneously
The thickness of disconnected adjustment plating iron layer, the quality of processed finished products extremely relies on the experience of workman, and automaticity is not high；
4th, the solder horn that the technology of iron layer is produced is plated outside existing copper embryo, copper embryo and plating iron layer are closed for inside and outside parcel
System, because electrodeposited coating is blocked up, causes workpiece irregular deformation, causes copper embryo and the Concentricity tolerance of plating iron layer very big, is carrying out
After turnery processing, the deviation for being wrapped in the thickness of the plating iron layer surrounding of copper embryo surrounding is larger, so when solder horn is in scolding tin, to the greatest extent
The thick place of pipe iron layer does not have bad, but the thin place of iron layer will first be eroded to the copper germinal layer of the inside by high temperature tin liquor, so as to iron
Iron head perforation can not normal work, this can also make it that the solder horn life-span is different in size, and quality is highly unstable.
5th, the solder horn that the technology of the existing foreign-plated iron layer of copper embryo is produced, can be after plating iron layer finishing shape again
One layer of decorative chromium is electroplated, due to technique limitation, the thickness of decorative chromium is not over 0.08mm, it is impossible to prolonged stop tin liquor
Corrosion, occurs that tin liquor can be gone to beyond working region upwards during solder horn use, can produce faulty operation.Because work
Make iron layer more and more thinner more than region, tin liquor can constantly corrode these iron layer until the copper germinal layer being corroded through below iron layer,
So that solder horn perforation can not normal work, this can also make it that the solder horn life-span is different in size, and quality is highly unstable.
Due to the presence of these defects, the production of solder horn is limited, uses and promotes, the production of high standardization is also limit
The formulation of process standard.
