Description

A kind of blaster fuse frame material complicated pluralism Cu alloy material and preparation method thereof
Technical field
The present invention relates to a kind of Copper Alloys for Lead Frame of complicated pluralism and preparation method thereof, belong to non-ferrous metal and add Work field.
Background technology
Hyundai electronicses information technology core component is integrated circuit, and it is mainly formed by chip and lead frame are encapsulated, Wherein lead frame mainly plays support chip, protection inner member, connection external circuit and outwards distributes the work of elements heat With being the critical material in integrated circuit.Copper alloy is widely used in materials of lead frame by its excellent conduction, heat conductivility Material.Exploitation and preparation for high property copper alloy rely primarily on alloying and fixation rates to realize, will low solid solution The alloy of degree is added in copper, and by higher temperature solid solution, alloying element forms supersaturated solid solution in copper, and intensity increases, Conductance declines, and then carries out Ageing Treatment, and a large amount of alloying elements are separated out in precipitated phase form, and even dispersion is distributed in Copper substrate In, electrical conductivity is lifted rapidly, simultaneously because the invigoration effect of precipitated phase, intensity further gets a promotion, in conjunction with working hardening, Finally give intensity and high conductive high property copper alloy.
Copper-based lead frame mainly has Cu-Fe-P (representative products have KFC and C194) and Cu-Ni- on domestic market Si (representative products have C7025) series, reaches performance requirement using solid solution+Ageing Treatment.By the alloying element for controlling Species and addition, different types of precipitated phase, content and shape characteristic can be obtained, the intensity of alloy and led so as to determine Electric rate.Generally, as the species and content that alloying element is added increase, intensity can be lifted gradually, conductance is gradually reduced. As KFC alloys Fe, P content are respectively 0.1% and 0.03%, alloy conductive rate is more than 80%IACS, and intensity has 400MPa or so, But as Fe contents gradually increase, during the Fe contents 2.4% of such as C19400, strength of alloy increases to 420~520MPa, but The conductance of alloy is reduced to 60%IACS or so.Therefore, suitable alloying element is added, rational production technology is made, The more excellent frame material of production combination property, promotes the fast development of product in China's Copper fabrication Domain Framework, is existing rank One of important topic of each Copper fabrication research of section and production unit.
The content of the invention
It is contemplated that the element-specific of copper-based middle addition, make and a set of be suitable for blaster fuse frame material complicated pluralism Cu alloy material and preparation method thereof, its conductance reaches 450~530MPa more than 75%IACS, tensile strength, and its is comprehensive Can be better than between KFC and C194 alloys.
The chemical composition of this alloy is:Fe:0.1~0.3%, Ni:0.1~0.25%, Sn:0.05~0.2%, P:0.03 ~0.08%, B:0.005~0.015%, Co:0.02-0.10%, remaining is Cu.
The reasons why illustrating this design of alloy, illustrates the effect of every element.
Iron:Can with p-shaped is into iron phosphorus precipitated phase or forms simple substance iron phase, can effective crystal grain thinning, delay to recrystallize Process, improves the intensity and hardness of copper alloy.Content is less than 0.1%, and the precipitation strength phasor of formation not enough, does not reach needs Reinforcing effect, too high levels, the Fe elements of solid solution in Copper substrate are excessive, can reduce the electrical conductivity of copper alloy, and the analysis for being formed Go out to strengthen phase morphology and size is partially coarse, the reinforcing to alloy is adversely affected.
Nickel element:Solution strengthening can be played a part of and promote hardening constituent to separate out, the addition of nickel element in addition can be with Increase the wetability of alloy, improve the welded encapsulation of blaster fuse frame material.
Tin element:Because tin atom differs larger with copper atom radius, a small amount of tin element is added in copper alloy, can caused Larger distortion of lattice, the motion of effective obstruction dislocation, especially in alloy stress relaxation, can effectively wind position Mistake, improves alloy stress relaxation-resistant.Additionally, the addition of tin element can also significantly improve the resistance to heat release performance of alloy.But work as Sn Constituent content, can severe exacerbation alloy conductive rate more than 0.5%.
P elements:Effect with solution strengthening, and nickel, while can be combined with nickel element, can be formed with deoxidation Phosphorus compound, can effectively hinder the motion of dislocation, improve the stress relaxation resistance of alloy.The intermetallic formed with iron Thing, precipitated phase dispersion-strengtherning is the main reinforcing means for lifting alloy strength, when phosphorus content is higher, the phosphorus of solid solution in Copper substrate Element is excessive, can significantly reduce the electrical conductivity of copper alloy.
Boron element:Increase the mobility of melt, crystal grain thinning tissue improves the intensity of alloy and improves alloy conductive Can, it is considered to which solubility of the boron element in copper is relatively low, B content scope preferably 0.005~0.015%.
Cobalt:The a small amount of cobalt of addition can form cobalt tin compound with tin, increase alloy strength, improve elastic limit.Meanwhile, it is bright The aobvious electric conductivity and fatigue performance for improving alloy, cobalt is close with copper atom radius in addition, acts on small to electron scattering.Consider Cobalt valency is higher, and cobalt content general control is 0.5~1.0%.
In addition to above-mentioned effect, the metallic compound formed between element and element also rises the element of addition to the performance of alloy Important influence, especially for such copper alloy for needing and carrying out fixation rates, the species of precipitation, is contained Amount, distribution and shape characteristic and remain in the performance to alloy of constituent content in copper-based solid solution and play decisive role, analyse Go out thing more, distribution more disperses, reinforcing effect is more obvious, and the iron, phosphorus element content in Copper substrate are more, and conductance is lower.This The main precipitate in ag(e)ing process of the alloy of Patent exploitation is Fe-P systems and Fe-Ni-P systems, and most Fe and P is first Element exists all in the form of intermetallic compound, and only a small amount of is solid-solution in Copper substrate, high-strength required for finally preparing Degree high-conductivity copper alloy.
In addition, it is of the invention in addition to being defined to Fe, P content, also to its atomicity percentage (i.e. Fe/P) Ratio is limited, i.e., and 0.5~4.0.When Fe/P values are less than 0.5, the P Excessive lysis for containing cause alloy in Copper substrate Conductance declines, and when Fe/P values are more than 4.0, the Fe excess for containing generates simple coarse Fe particles in the alloy, causes Alloy strength reduction.Therefore, most the scope of Fe/P is defined as 0.5~4.0 at last.
In addition, the present invention also provides the preparation method of above-mentioned complicated pluralism blaster fuse frame material.
