Abstract
The invention discloses a tin solder of an anti-ageing solder strip, which consists of Sn, Bi, Sb, Ge, In, Pb and (SnP+Ga), and belongs to the field of solar power generation science and technology. The tin solder comprises the following components in percentage by weight: 59-61% of Sn, 0.01-1.0% of Bi, 0.01-2.0% of Sb, 0.005-1.0% of Ge, 0.005-1.0% of In, and the balance of Pb. The tin solder has the following characteristics: the tin solder has excellent solder liquidity to improve the weldability on a welding silicon wafer; a trace of Ge element is added to enhance the anti-ageing capacity of solar power in the natural environment so as to prolong the service life of a solar power generation set; as the bismuth element is added, after tin is coated on a copper strip, the surface of the tin coating layer is bright, tidy and smooth without such defects as burrs; the antimony element is added to enhance the welding strength and the surface brightness of the tin coating layer; and as the anti-ageing tin alloy is added, slag ash in the liquid level of the tin solder is largely reduced, and the quality of the coating layer is improved.
Description
Technical field
Patent of the present invention relates to solar photovoltaic technology, especially a kind of scolding tin material of anti-aging photovoltaic welding belt.
Background technology
Utilizing solar energy source generating is in the world for the new forms of energy of color environmental protection, the critical piece that makes solar energy be converted into electric energy is photovoltaic battery panel, and cell panel key component is silicon wafer and photovoltaic welding belt, welding base-material is copper strips, must plate one deck tin solder, therefore the quality of tin solder quality is the important technical indicator of photovoltaic generation effect, current photovoltaic welding belt technique 100% is hot tinning technique, can adopt tin solder to be greater than 99% for the plumbous series solder of tin, use the lead-free solder of several products of outlet about electronic technology, in photovoltaic welding belt technique, be not also used, belong in embryo, therefore European Union's ROHS instruction is had no to association, electronic welding technique and photovoltaic welding belt tin plating technique, because of product performance different, tin solder quality photovoltaic is required higher than electronic welding technological requirement with tin solder.Photovoltaic tin solder has its special requirement: have good electric conductivity; The zinc-plated idol of photovoltaic welding belt will be welded on silicon wafer, and its solderability requires high, otherwise can cause rosin joint, dry joint phenomenon; Tin coating will stand Exposure to Sunlight rain at cell panel and play the test of severe large natural environment, require tin solder must not oxidation, variable color, aging, to reach the service life of 25 years.
Though foreign data has been added 2% silver element on sn-pb basis in recent years, the tin solder of composition sn63%, ag2%, pb36%, is that scolder has been listed Japanese JIS standard in, is relatively early but adopt above-mentioned scolder in Germany on photovoltaic welding belt tin plating technique.
Summary of the invention
The object of the invention is in order to solve the problems of the technologies described above, the technical scheme providing is: 1, a kind of scolding tin material of anti-aging photovoltaic welding belt, is characterized in that its metallic element is formed by Sn, Bi, Sb, Ge, In, Pb.
Further, the scolding tin material part percentage by weight of the anti-aging photovoltaic welding belt of described one is Sn 59-61%;
Part percentage by weight is Bi 0.01-1.0%;
Part percentage by weight is Sb 0.01-2.0%;
Part percentage by weight is Ge 0.005-1.0%;
Part percentage by weight is In 0.005-1.50%;
Part percentage by weight is that Pb is surplus.
beneficial effect:
(1) its characteristic has good solder fluidity.Improve solderability on welding silicon chip.
(2) add micro-Ge element and impelled solar energy ageing resistance in natural environment, can extend the service life of solar electrical energy generation unit.
(3) added bismuth element and made after copper strips is zinc-plated, tin coating surface-brightening is clean and tidy, smooth, without defects such as burrs.
(4) added antimony element, it has strengthened weld strength and tin coating surface brightness.
(5) add anti-oxidant ashbury metal, closed tin solder liquid level and reduce in a large number slag ash, improved quality of coating.
Detailed description of the invention
A kind of tin solder of anti-aging welding tin coating, its invention main points are to have its tin coating of use procedure that welding tin solder is converted into electric energy at solar energy on silicon chip battery plate to have aging-resistant functional characteristic.Can improve service life energetically.
(1) alloying element Sn, the Bi of tin solder, Sb, Ge, In, Pb, (SnP+Ga) composition.
(2) composition mass percent is
Sn59-61% Bi0.01-1.0% Sb0.01-2.0%
Ge0.005-1.0% In0.005-1.0% Pb is surplus
(3) this tin solder method of manufacturing technology takes following smelting process step to complete.
As the high-melting-point non-ferrous metal element in alloy composition must take intermediate alloy smelting process to implement, concrete technical measures are as follows:
(1) Sn, Sb intermediate alloy proportioning are Sn50% Sb50%, and the smelting furnace of Sn, Sb alloy is medium-frequency induction furnace.First rise to >700 DEG C by dissolving rear liquid temperature in the tin pot of the pure tin ingot input electric furnace of content >99.95%, then drop into through breaking dry #1 star antimony ingot into pieces.In high temperature tin liquor, and constantly stir with dry waddy, short with antimony slab fusing,, through stirring, scum all after fusing until antimony slab, ingot casting is through assay, and it could be for subsequent use after answering >49.5% containing Sb composition.
(2) proportioning of Sn Ge intermediate alloy is Sn 99% Ge1.0%, in view of the fusing point of Ge element is 960 DEG C and its physical property has the Determination of Rare-Expensive Elements of easy distillation, thus there is particular/special requirement at smelting process, could be by its chemical composition stability.
The smelting furnace of Sn Ge alloy is also induction middle frequency furnace.First the pure tin ingot of content >99.95% is dropped in the pincers pot of induction middle frequency furnace.After all melting, liquid temperature rises to 1100 DEG C.And drag for the scum silica frost of detin liquid, must drop into potassium oxide and be about 10m/m thickness in tin liquor as its amount of coverture.In the time that tin liquor temperature arrives 1100 DEG C, the pure germanium ingot of >99.99% content is clamped with instrument, invested in high molten tin liquor and melt, until all melted.Then stir Sn Ge with pure titanium rod and add up to, impel chemical composition stability even.And after calmness in >30 minute, remove potassium oxide coverture remnants on liquid level.After purification, stir 3 minutes, ingot casting is for subsequent use again.
(3) at the smelting synthesis technique that has prepared its overall tin solder after Sn Sb and Sn Ge intermediate alloy.Smelting furnace uses can be temperature automatically controlled, the electric furnace of automatic stirring function.Ashbury metal melt is 1000 kilograms, and process first drops into <99.95% lead pig.Throw in >99.95% tin slab above, can prevent that tin slab cooling from can reduce again energy resource consumption, plays preheat function.Temperature control is 320-350 DEG C.Make Sn Sb element in conjunction with stable through automatic stirring >15 minute, then except removing slag after ash drops into anti-oxidant ashbury metal again to enter after Sn Sb alloy melting---pure Bi must melt under liquid---after the fusing of Sn Ge intermediate alloy---pure In(indium grain) all after fusing, must after >15 minute, drag for removing dross ash and add (SnP+Ga) alloy by automatic stirring.After being incubated calm >30 minute, stir 5 minutes 320-350 DEG C of alloy liquid temperature, ingot casting completes tin solder product again.
