Abstract
A kind of rare earth-tin-lead solder and preparation method.It is on the basis of the plumbous series solder of known tin, the plumbous silver-colored series solder of tin, adds alterant norium or single metallic cerium, makes grain refinement, adds P elements, improves the product antioxygenic property.Rare earth-tin-lead solder is compared with known HLSnpb39 tin-lead solder, the product light, and its stanniferous amount reduces by 5～7%.Physicochemical property, serviceability are all more superior, and scolder per ton is saved refined tin 50-70 kilogram.Be applicable to the scolder in welding of electronics industry line and the components and parts assembling.
Description
The present invention relates to a kind of used in electronic industry rare earth-tin-lead solder and preparation method.
In the electronics industry, known slicken solder is with the most use with tin-lead series and tin-lead-Yin series at present.For certain welding purpose, also a small amount of golden series solder, aluminium series solder, plumbous series solder, tin series solder, indium series solder, zinc series solder of adopting.The scolder that these are serial perhaps because of price is too high, perhaps because of the reason of performance own, is restricted its purposes.Tin-lead series, tin-lead-Yin series solder, various in style, and also of many uses.But general many products with stanniferous 55～65%, the most plumbous eutectic composition of tin scolders that adopt stanniferous 61.9% on transfer matic.In recent years, because the tin valency goes up, cause the product cost of high tin content to rise.
The purpose of this invention is to provide a kind of rare earth-tin-lead solder improves the product antioxygenic property and improves welding performance.
Solution of the present invention is to add alterant norium or single metallic cerium with the intermediate alloy form, makes grain refinement; Add the antioxygen element phosphor with the intermediate alloy form and improve the product antioxygenic property.Chemical composition of the present invention is as shown in table 1.
Table 1 chemical composition of the present invention (%)
| Tin | Plumbous | Antimony | Rare earth | Silver | Copper | Phosphorus | Indium |
| 54～55 | 39～45 | 0.09～0.1 | 0.003～0.01 | 0.013～0.05 | 0.08～0.1 | 0.003～0.008 | 0.005～0.02 |
For the accurate chemical analysis of control alloy, rare earth metal, phosphorus, copper, antimony, silver is respectively with rare earth-lead, copper phosphorus-Yin, and antimony-Xi, binary or ternary alloy three-partalloy form add.And use topped dose of multicomponent system fused salt, reduce scaling loss.
Rare earth-tin-lead solder is compared surface-brightening with known HLSnPb39 tin-lead solder, and antioxygenic property is good, and its stanniferous amount reduces by 5～7%, and scolder per ton is saved refined tin 50-70 kilogram.Compare with known HLSnPb39 tin-lead solder, the physicochemical property of rare earth-tin-lead solder and serviceability are all more superior.The physical property test result is as shown in table 2.
Table 2 physical property of the present invention
| Fusing point ℃ | Than gross ton/centimetre 3 | Tensile strength kilogram/millimeter 2 | Peel strength kilogram/millimeter 2 | Diffusivity % | Resistivity Europe-centimetre |
| 183～190 | 8.6 | 5.71 | 12.10 | >86 | 11.2 |
Optimum implementation of the present invention is: with graphite crucible with No. 1 tin of spy, a lead, 201 phosphor-coppers, cerium-2, No. one star metal is made the rare-earth-lead alloy that contains 10% rare earth respectively, the ag-cu-p alloy that contains 23% silver medal contains the antimony ashbury metal of 78.7% antimony, and these intermediate alloys are cut into small pieces.
With tin, the plumbous adding in the casting iron pan, heat fused is warming up to 300～400 ℃ and adds intermediate alloy then, stir after waiting to melt, solder of the present invention.
After rare earth-tin-lead cast rod, adopt known SS1-3 type activated rosin flux,, and pull into the welding wire of φ 0.8～φ 2.0 mm dias, be suitable for doing in the electronics industry line welding and use by single core or the moulding of multicore mould time processing.
Another embodiment of the invention is: rare earth-tin-lead solder is made the scolder of all size and shape, be suitable for using in the assembling procedure of electronics industry components and parts, and tin content also can continue to reduce.
Claims (3)
1, a kind of rare earth-tin-lead solder, it is characterized in that stanniferous 54～55% by weight, lead 39～45%, antimony 0.09～0.1%, rare earth 0.003～0.01%, silver 0.013～0.05%, copper 0.08～0.1%, phosphorus 0.003～0.008%, indium 0.005～0.02%, rare earth metal is an alterant, and phosphorus is antioxidant.
2, rare earth alloy scolder according to claim 1 is characterized in that the alterant rare earth metal is to add with rare earth-Xi bianry alloy form.Antioxidant phosphorus is to add with phosphor-copper-Xi form.
3, rare earth alloy scolder according to claim 1, it is characterized in that can be by single core or the known activated rosin flux time processing moulding of multicore mould adapted, and pulls into the active welding wire of φ 0.8～φ 2.0 mm dias.
