Description
Technical field
Employed Cu-Ni-Si alloy during the electronic unit that the present invention relates to intensity and high conductive electronic material etc. is made.
Background technology
To employed copper alloys such as the various terminals of lead frame, electronics, junctors, require to have both high strength and high conductivity.In addition, in recent years, on the various terminals of lead frame, electronics, junctor etc., making fast progress of increases such as pin count, fine pithization requires electronic unit to have High Density Packaging, high reliability.These have also proposed more and more tight thin plateization, excellent processability, high characteristic requirements such as electric conductivity to employed material in the electronic unit.
Employed material require has high strength and high conductivity on the various terminals of lead frame, electronics, junctor etc., and from the viewpoint of the lightweight of electronics class and parts, high strength, high conductivity, the usage quantity of age hardening type copper alloy is increasing, and is the solution strengthening type alloy of representative in order to replace with existing phosphor bronze, brass etc.Age hardening type copper alloy, by the supersaturated solid solution through solution treatment is carried out ageing treatment, minuteness particle is separated out equably, thereby improve mechanical characteristicies such as tensile strength, yield strength, elastic limit value, simultaneously, the solid solution element amount in the copper reduces and the raising electric conductivity.
In the age hardening type copper alloy, the Cu-Ni-Si alloy is the representative copper alloy that has high strength and high conductivity concurrently.This copper alloy is separated out because of compound particles between fine Ni-Si metalloid intensity and electroconductibility is improved, as the material of the various terminals of lead frame, electronics, junctor etc. and be applied (for example, referring to Patent Document 1).
Patent documentation 1 special hope 2000-018319
The Cu-Ni-Si alloy utilizes between the Ni-Si metalloid compound particles to separate out to improve intensity and electroconductibility.But the intensity and the electric conductivity of alloy are generally inverse relationship, and intensity height then electroconductibility is low, and electroconductibility height then intensity reduces.The situation of Cu-Ni-Si alloy is, if Ni that is added and Si are lower concentration, the solid solution element that does not then form the precipitate of compound particles between the Ni-Si metalloid reduces, although can obtain sufficient electroconductibility, but because concentration is low, so the amount of separating out reduces, intensity is insufficient.On the other hand, if be high density, then the amount of separating out increases, although obtain full intensity, and, the solid solution element that does not form the precipitate of compound particles between the Ni-Si metalloid increases, thereby the not high enough problem of electroconductibility is arranged.
Summary of the invention
The present invention makes for addressing the above problem, and purpose is to provide a kind of electronic material that has high strength and high conductivity concurrently Cu-Ni-Si alloy.
For addressing the above problem, the inventor has finally successfully developed the Cu-Ni-Si alloy that has high strength and high conductivity concurrently through too much kind of research Cu-Ni-Si alloy.
That is, technical scheme of the present invention is as follows:
(1) the Cu-Ni-Si alloy that has high strength and high conductivity concurrently is characterised in that, it be contain 1.0～4.5% Ni, 0.25～1.5% Si, all the other are the copper base alloys that are made of Cu and unavoidable impurities, [Ni]/[Si] when the mass concentration of Ni and Si is [Ni], [Si], Ni and Si is 4～6, and be that to make (formula 1) defined x be 0.1～0.45 [Ni], [Si]
([Ni]-4x)
2([Si]-x)=1/8 ... (formula 1).
(2) above-mentioned (1) described Cu-Ni-Si alloy is characterised in that, contains 0.05～0.3% Mg.
(3) the described Cu-Ni-Si alloy in above-mentioned (1) or (2) is characterised in that, contains total amount and be among 0.005～2.0% Zn, Sn, Fe, Ti, Zr, Cr, Al, P, Mn, Ag or the Be more than one.
As mentioned above, alloy of the present invention has good intensity and electroconductibility, is suitable as copper alloy for electronic material such as lead frame, terminal, junctor.
Concrete form of implementation
Then, to being specifically described according to above-mentioned such reason that limits the compositing range of copper alloy in the present invention.
Ni and Si concentration
By carrying out ageing treatment, Ni and Si form with fine Ni
2Si is the precipitation particles of master's intermetallic compound, and the intensity of alloy is increased significantly, on the other hand, also improves electroconductibility significantly.But, Ni concentration was less than 1.0% o'clock, or Si concentration even add another kind of composition, also can not get desirable intensity less than 0.25% o'clock.In addition, Ni concentration was above 4.5% o'clock, or Si concentration was above 1.5% o'clock, although acquisition full intensity, but electroconductibility reduces, and, generating in parent phase does not have the thick Ni-Si class particle (crystallisate or precipitate) of help to improving intensity, and causes bendability, etching and coating decline.Therefore, Ni concentration is decided to be 1.0～4.5%, Si concentration is decided to be 0.25～1.5%.
[Ni]/[Si] mass concentration ratio
If the amount of the solid solution Ni in the alloy and the amount of solid solution Si reduce, then electric conductivity increases.If the Cu-Ni-Si alloy is carried out ageing treatment, then Ni
2Si separates out, and the amount of solid solution Ni and the amount of solid solution Si is reduced, thereby improve electric conductivity.The amount of solid solution Ni after the timeliness and the amount of solid solution Si increase and decrease according to the relation (formula 1) of solubility product described later.For example, if the ratio of Ni concentration in the alloy and Si concentration ([Ni]/[Si]) increases, then the amount of solid solution Ni increases, and the amount of solid solution Si reduces.On the other hand, if the influence degree that electric conductivity is reduced compares, then solid solution Si amount is big more a lot of than solid solution Ni amount.Therefore, give [Ni]/[Si] and precipitate Ni of maximum conductivity
2Ni/Si among the Si is more inconsistent than (=4.18).
The inventor studies the relation of [Ni]/[Si] and transmission of electricity rate by experiment, thereby clear and definite: in order to obtain high conductivity, need [Ni]/[Si] is adjusted in 4～6 the scope, preferably be adjusted in 4.2～4.7 the scope.This is formed with respect to Ni
2The composition of Si is the superfluous slightly composition of Ni.
Because [if Ni]/[Si] be less than 4, then the amount of solid solution Si increases, thus electric conductivity significantly descend, and when thermal treatment easily at material surface generation silicon oxide film, thereby cause solderability and coating variation.On the other hand, if [Ni]/[Si] surpasses 6, then the amount owing to solid solution Ni increases, so, can not get desirable electric conductivity.
About (formula 1)
The Cu-Ni-Si alloy passes through Ni
2The Si particle separate out raising intensity.As previously mentioned, from the viewpoint of electric conductivity, with respect to Ni
2The composition of Si, the amount of Ni surplus slightly are good a bit.It is believed that in the past, when such Ni is superfluous, Ni
2The amount of separating out of Si particle is decided by the concentration of Si.That is, people think that always under the situation of the composition of Ni surplus, the intensity after the timeliness is decided by Si concentration.
The inventor is with the basis that consists of of the Ni surplus that can obtain high conductivity, the relation of Ni and Si concentration and intensity has been carried out research repeatedly, found that, even Si concentration is identical, [if Ni]/[Si] difference, produce the intensity difference of tens of MPa when then big, and might not there be correlationship in Si concentration and intensity.In other words, found decision Ni
2The parameter of the amount of separating out of Si is not a Si concentration.
And, based on consideration, experimental data being resolved solubility product, the result is about Ni and Si concentration and Ni
2The relation of the amount of separating out of Si has obtained following empirical formula.
([Ni]-4x)
2([Si]-x)=1/8 ... (formula 1)
Here, x is the parameter of the expression amount of separating out.More particularly, the Si concentration that x is equivalent to separate out, the Ni concentration that 4x is equivalent to separate out.Therefore, ([Ni]-4x) is equivalent to the Ni concentration of solid solution, and ([Si]-x) is equivalent to the Si concentration of solid solution.
Intensity after the timeliness has shown the correlationship stronger with this x.That is, obtain desirable intensity, therefore, utilize (formula 1) that [Ni] and [Si] got final product for suitable value by x being adjusted into suitable value.As mentioned above, the parameter x by import showing precipitation state and according to the relation of solubility product adjust Ni and Si concentration, the technology of controlling the intensity after the timeliness is that the present invention finds first.
The value of solubility product (the right of (formula) 1) is the function of temperature.Under the low temperature, this value is little, that is, if carry out ageing treatment at low temperatures, in theory, the amount of precipitate increases, thereby obtains the material of high strength, high conductivity, and still, this is the theory under equilibrium state eventually.In order at low temperatures metallic substance to be carried out ageing treatment up to reaching equilibrium state, need near unlimited aging time.The inventor has investigated various compositions and precipitation state, thereby clear and definite: solubility product is 1/8 with respect to the appropriate value of industrial ageing treatment, and the x value of this moment then can be at the industrial material that stably obtains high strength, high conductivity if 0.1～0.45.
Mg concentration
Although Mg has the effect of improving the stress relaxation properties significantly and the effect of improving hot workability, if but less than 0.05%, then can not get this effect, if surpass 0.30%, because the heat-resisting separability of castibility (surface quality of continuous castings decline), hot workability and coating descends, so the concentration of Mg is decided to be 0.05～0.3%.
Zn, Sn, Fe, Ti, Zr, Cr, Al, P, Mn, Ag or Be
Zn, Sn, Fe, Ti, Zr, Cr, Al, P, Mn, Ag or Be have intensity and the stable on heating effect that improves the Cu-Ni-Si alloy.In addition, wherein Zn also has the stable on heating effect that improves the solder joint, and Fe also has makes the effect of organizing miniaturization.In addition, Ti, Zr, Al and Mn have the effect of improving hot rolling.Its reason is that these elements so form compound with sulphur, are segregation from sulphur to the grain boundary of ingot casting thereby reduced the reason that produces hot-rolled crackle owing to strong with the affinity of sulphur.If the concentration total amount of Zn, Sn, Fe, Ti, Zr, Cr, Al, P, Mn, Ag or Be then can not get above-mentioned effect less than 0.005%, if total content surpasses 2.0%, then electroconductibility significantly descends.Therefore, the total content with them is decided to be 0.005～2.0%.
[embodiment]
Then, embodiments of the invention are described.The copper alloy that various one-tenth shown in the his-and-hers watches 1 are grouped in the air melting stove carries out melting, and is cast as the ingot casting of thickness 30mm.

Then, hot rolling is 9mm to thickness, for after removing surperficial scale and carrying out face cutting, by the cold rolling plate of making thickness 1mm.Afterwards, under 750 ℃～850 ℃ temperature, carry out solution treatment, then, be cold rolled to thickness 0.4mm.And, for the composition of each alloy, become the ageing treatment of carrying out under the peaked temperature 3 hours in tensile strength.This temperature range is 400 ℃～600 ℃.And, with the cold rolling plate of making thickness 0.25mm.In the intensity of utilizing the sample after tensile strength is estimated final thermal treatment on the tensile testing machine.Utilize electric conductivity (%IACS) to estimate electroconductibility by four-terminal method.In addition, the value of [Ni]/[Si] and x is estimated with (zero) in the scope of technical scheme 1, estimates in its scope external application (*).Show the result in table 1.
As shown in Table 1, the value of example No.1～No.13 [Ni]/[Si] and x is all in the scope of technical scheme 1.Therefore, the tensile strength of example is that 720MPa is above, electric conductivity is more than the 45%IACS, has high strength, high conductivity.
And example No.2, the No.4, No.6, No.7, the No.8 that have added Mg in order to improve the stress relaxation properties are also the same with the example that does not add Mg, have obtained high intensity and electric conductivity.
In addition, more than one the example No.7～No.13 that has added total amount and be among 0.005～2.0% Zn, Sn, Fe, Ti, Zr, Cr, Al, P, Mn, Ag or the Be does not compare with there being the example No.1～No.6 that adds, although electroconductibility is poor slightly, the intensity aspect is good.
On the other hand, observe comparative example, because the x value of No.14 and No.16 is greater than 0.45, so intensity does not increase so, the electric conductivity reduction.This be because, generated the cause that intensity is not had the thick Ni-Si class particle (crystallisate and precipitate) of help.Although No.15 has demonstrated high electric conductivity, owing to mean that the x value of the amount of separating out is low, intensity reduces.[Ni] of No.17/[Si] is low, the Si surplus, thus electric conductivity is reduced.[Ni] of No.18/[Si] height, solid solution Ni is many, thereby electric conductivity is reduced.No.19 is because the x value is high and [Ni]/[Si] is low, so electric conductivity significantly reduces.
No.20 so the poor in processability in the hot rolling cracks, and can not carry out back step operation because the addition of Mg is too many.
In No.21～No.23, because the total amount when adding element more than a kind among Zn, Sn, Fe, Ti, Zr, Cr, Al, P, Mn, Ag or the Be has surpassed 2.0%, so electric conductivity significantly reduces.
