Abstract
A kind of multiple tin metal band, opens up fluted on copper metal substrate, and the tin band concordant with the groove is provided in the groove；The tin band is prepared with following methods: so that tin bar melting is saturated with the groove under inert protective atmosphere and is formed the tin band.The multiple tin metal band tin band is concordant with metallic substrate surface, generous uniform, performance Uniformly stable；Metal oxide generates between reducing tin copper caused by hot-working；Metal base thickness is thinned at multiple tin, and current cross section reduces, and the low power protective value that fuse is prepared with it can be improved.
Description
Technical field
The present invention relates to metal material field, the composite strip of other compound metals on conductive base is referred in particular to.
Background technique
Melt is the core component of fuse, usually by substrate punching, ward off tin and molding is completed, such as Fig. 1 wards off tin operation one
As be manual work or automatic machine operation, the shortcomings that warding off tin width, uneven thickness can be generated, influence the performance of melt；And
Temperature is higher when warding off tin, and operation may generate dystectic intermetallic compound or tin without atmosphere protection between tin and substrate
Oxide, cause melt low power fusing difficulty increase；And tin is placed in metallic substrate surface, easily scatters after melting narrow to melt
At diameter, the transfer of M effect point makes product fuse in advance.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of multiple tin metal composite strip, tin width and thickness thereon
Unanimously, the consistency of performance using the melt of material production is good.
In order to solve the above technical problems, technical solution provided by the invention is a kind of multiple tin metal band, it is characterised in that
It opens up on metal base fluted, tin band is provided in the groove.
The metal base is Copper base material.
The present invention also provides multiple tin metal band production method, its step are as follows: 1) opening up on metal base recessed
Slot；2) composite strip is made in insertion tin band in a groove, and the tin band of composite strip is concordant with metal base upper surface.Its described step
It is rapid 2) to be flattened the insertion of tin band in the groove by cold working mode.
The present invention also provides another production methods of multiple tin metal band, and its step are as follows: 1) on metal base
Open up groove；2) it is implanted into tin bar in a groove；3) tin bar melting is made to be saturated with the groove under inert protective atmosphere.Tin bar merging
After the groove, both ends are fixed in the groove by welding or bonding mode.4) by cold working mode that tin is with pressure
It puts down in the groove.
Above-mentioned metal base material is copper.
Multiple tin metal band of the invention, due to being cold-pressed tin band in a groove or being saturated with the tin bar being placed in groove melting
Groove limits tin bandwidth and thickness by groove, keeps the upper surface of tin band concordant with metal base upper surface, guarantees melt
There can be good consistency.Due to not generating metal between tin and substrate interface using cold pressing or the molten tin under protective atmosphere
Between compound or metal oxide, therefore the unicity of this composite material is preferable；Due to the embedding tin of strip, the copper of multiple Xi Chu
Thickness degree is thinned, and current cross section product reduces, and the low power protective value of fuse can be improved in the enhancing of M effect.
Detailed description of the invention
Fig. 1, existing Preparation technology for melt process.
Fig. 2, existing melt ward off partial enlargement side view schematic diagram at tin.
Fig. 3, the partial enlargement side view schematic diagram of multiple tin metal band of the invention.
Specific embodiment
Scheme in view of the above technology is now lifted preferred embodiment and is specifically described in conjunction with diagram.
Multiple tin metal band of the invention is mainly included on metal base 3 referring to Fig. 3 and offers required tin bandwidth
The ready-made tin band to match with groove shapes is imbedded by way of cold pressing and forms gold in groove by the groove of degree and thickness
Belong to the multiple tin tin band 4 on substrate, while under cold pressing effect, is firmly combined tin band with metal base, flush.
Be embedded in using cold pressing, can to avoid the difficult hot worked disadvantage of tin, meanwhile, the method for cold pressing also avoids hot-working
When, compound or metal oxide between the refractory metal formed between tin band and substrate due to high temperature are this dystectic
The M effect (metallurgical effect) for warding off Xi Chu of melt can be greatly reduced in compound, and therefore, the traditional soldering iron head that compares wards off the work of tin
Skill, multiple tin metal band prepare the properties of product of melt more preferably.
In order to which tin is stronger in conjunction with metal base, groove is opened up on metal base 3, is then placed on tin bar recessed
In slot, then tin bar is fixed, groove both ends fix it tin bar welding by fixing means, or using modes such as bondings
It is fixed.Being sent in solder furnace under protective atmosphere (inert atmospheres such as helium, nitrogen) makes tin bar melting be saturated with groove
Form the multiple tin tin band 4 on multiple tin metal band.Generally use belt, chain type solder furnace.Diameter and the length selection of tin bar are molten
Groove is just saturated with after melting.Finally, being handled by cold pressing mode composite surface.
The metal base of above-described embodiment is conductive metallic material, generallys use copper metal as metal base, can also be with
Select other conductive metals as metal base as needed.Tin band is embedded in gold by cold pressing by above-mentioned two production method one
Belong to and multiple tin metal band is made in substrate, one is to be saturated with groove by tin bar melting under protective atmosphere multiple tin metal band is made
Material.Two methods limit the width and thickness of multiple tin tin band by groove, make the multiple tin tin band of production is generous to be consistent.
The melt of multiple tin metal band production of the invention, due to the presence of groove, the width of the tin band on metal base
Almost the same with the width and thickness of thickness and groove, the melt property of error very little, the multiple tin metal band production is stablized；By
In the embedding tin of strip, thus tin layers than directly ward off tin can with it is thin very much, the metal thickness of multiple Xi Chu is thinned, and electric current is subtracted by section
Small, the enhancing of M effect can also be improved the low power protective value of fuse；Keep tin bar molten due to being cold-pressed or taking under protective atmosphere
Melt, avoids the interface alloy cpd for warding off the generation of tin process.Since traditional melt production is to cut out the metal base for not warding off tin
It is cut to melt, then carries out warding off tin on melt, makes the tin band on melt.Melt production of the invention is on metal base
Tin band is set, is then just cut out as melt, the process for warding off tin after cutting out is saved, reduces production cost.
