Description
Technical field
The utility model is related to a kind of tinplate structure, more particularly to one kind can soldering and corrosion resistant tinplate.
Background technology
The material of electronic component purposes needs good soldering and corrosion resistance, it is general use Ni sills, but
It is that W metal is rare, precious metal, expensive, it is difficult to promote, popularize.And general tinplate material is difficult to meet high pricker
Weld the requirement of performance and improved corrosion performance.
General reflowed tinplate material, because electroplating surfaces with tin thickness degree is not enough, so brazing property is not good.Simultaneously soft
Layer gold link is fused, the ferro element of substrate can be migrated to tin coating, causes tin coating to reveal iron degree and aggravate (raising of ISV levels),
So the performance of salt spray test is also poor.General reflowed material is difficult to meet electronics zero in terms of soldering and corrosion resistance
The requirement of part material.
Utility model content
To solve the problems of the prior art, the utility model provides one kind can soldering and corrosion resistant tinplate.
The utility model includes substrate, the tin coating being respectively overlay in the substrate upper and lower surface, is covered in the plating
Passivation film and the oil lamella being arranged on the passivation film in tin layers.
The utility model is further improved, and the thickness of the tin coating is 2.8~19.0 grams/m.
The utility model is further improved, and the thickness of the tin coating is 5~16.0 grams/m.
The utility model is further improved, and the thickness of the tin coating is 11.2 grams/m.
The utility model is further improved, and the raw material of the passivation film is sodium dichromate and chromic acid.
The utility model is further improved, and the quality of chromium is 6.0~8.0 millis gram/m in the passivation film.
The utility model is further improved, and the quality of chromium is 7.0 millis gram/m in the passivation film.
The utility model is further improved, and the oil lamella thickness is 5.0~7.0 millis gram/m.
The utility model is further improved, and the oil lamella thickness is 6.0 millis gram/m.
Compared with prior art, the beneficial effects of the utility model are：Material surface is higher because of free tin thickness, has
Good brazing property, the utility model material possesses high soldering, strong corrosion resistance, Ni sills can be replaced to be applied to electronics
Part purposes, saves rare, precious metal, reduces cost.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
As shown in figure 1, material of the present utility model is not reflowed, with lime colored appearance, substrate 1, difference are specifically included
The tin coating 2,3 of the upper and lower surface of substrate 1 is covered, the passivation film 4,5 of the tin coating 2,3 is covered and is arranged on described blunt
Change the oil lamella 6,7 in film layer 4,5.
The utility model material carries out rational tin plating, passivation by lower surface on substrate 1, applies oil processing, and material is not
It is reflowed, with lime colored appearance, material surface is higher because of free tin thickness, with good brazing property.Because in coating
Ferro element is less, coordinates the appropriate thickness of passivation layer 4,5, and material has preferable corrosion resistance.
The thickness of this example tin coating is 2.8~19.0 grams/m, particularly between 5~16.0 grams/m, full
The high brazing property of foot, the thickness of preferably described tin coating is 11.2 grams/m or so.
This example is set to further strengthen the oxidation resistance of tinplate and assign material good Paint Adhesion energy
Passivation film 4,5, the raw material of the passivation film 4,5 is the quality of chromium in sodium dichromate and chromic acid, the passivation film 4,5
For 6.0~8.0 millis gram/m, the quality of preferred chromium is 7.0 millis gram/m, material is had more preferable corrosion resistance
Energy.
The surface of passivation film 4,5 sets oil lamella 6,7, plays protection plate surface from oxidation, abrasive effect,
It can also refer to as required lubricating film in successive process (subsequent handling such as winding, trimming, rip cutting, shaping), oil lamella 6,7
Last treatment process of tinplate surface, the thickness of oil lamella 6,7 is 5.0~7.0 millis gram/m, preferably 6.0 millis
Gram/m, this example oil lamella 6,7 uses DOS (SA dibutyl ester) oil, and color is faint yellow, and molecular weight is
Density is that 0.913 ± 0.003, Dos oil can be extracted from mineral or obtained by chemical synthesis at 426.68,25 DEG C.
The utility model material possesses high soldering, strong corrosion resistance, Ni sills can be replaced to be used applied to electronic component
On the way, rare, precious metal is saved, the cost of electronic component is effectively reduced.
Embodiment described above is better embodiment of the present utility model, and it is new not to limit this practicality with this
The specific implementation scope of type, scope of the present utility model includes being not limited to present embodiment, all according to the utility model
The equivalence changes made are in protection domain of the present utility model.
