本発明は銅合金板および条の製造方法に関し、１！に＃
細に敵手導体機器のリードフレーム相等としての銅合金
板および条の製造方法に関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a method for manufacturing copper alloy plates and strips, and provides 1! #
In particular, this invention relates to a method for manufacturing copper alloy plates and strips as lead frames for conductor equipment.
従来、半導体機器のリードフレーム相ＫＨ１熱膨張係数
の小さい鉄ニツケル合金（Ｆｅ−４２％Ｎｉ。Conventionally, the lead frame phase KH1 of semiconductor equipment is an iron-nickel alloy (Fe-42%Ni) with a small coefficient of thermal expansion.

一方ではコストダウンのための銅系材料の使用比重増も
背景にある。On the other hand, there is also an increase in the use of copper-based materials to reduce costs.
銅糸判料に要求される特性としては放熱性の点は当然の

の強度面での％例の影響を大きく受けるものである。Heat dissipation is a natural requirement for copper threads, but in the production of ICs or LSIs, heat resistance and deformation resistance can greatly affect product yields, and also require mounting after product manufacturing. The mounting yield in automatic assembly is greatly affected by the strength of the lead frame phase.
本発明は、半導体機器用杓の強度とｉｔ熱性を改善すべ

とＫある。An object of the present invention is to provide a processing method for radically processing a Cu-Ni-P alloy into strips in order to improve the strength and thermal properties of a ladle for semiconductor devices, in other words, to provide a method for manufacturing copper alloy plates and strips. .

Contains i1.0-4.0%, P 0.2-0.8%,
At least once at 700°C during annealing prior to finish rolling of an alloy ingot, the balance of which is Cu and unavoidable impurities.
A heat treatment of heating and water cooling is performed to ~900℃, and the heat treatment after this heat treatment is 500℃ including the heat treatment before heating.
It is characterized by being carried out at temperatures below ℃. Jin's method is C
The u-Ni-P alloy generates an intermetallic compound depending on the mixing ratio of Ni and P, and contributes to the generation and dispersion of this intermetallic compound. That is, a heat treatment step in which the alloy is heated at a high temperature (700-900'C) to bring Ni and P into a solid solution state, and a heat treatment step (200-900'C) in which aging stability is caused to improve heat resistance and strength. 550
It consists of two heat treatment processes (°C), which are basically combined with cold working.

After cooling with water from 00 to 900°C and adding cold working to this, heat treatment may be performed at 200 to 500°C for 10 minutes or more, and further cold finish rolling may be performed.

) Cooling is performed more slowly than in the solid solution state at 700 to 900°C, generating intermetallic compounds during cooling, and it is often possible to measure an improvement of 4 degrees already in the annealed state, and (Vi)
It is also possible to perform further heat treatment after finish rolling as a treatment for strain relief V annealing by cold working and for compensating for the formation of intermetallic compounds during cooling.

である。It is clear that the metal plates and strips have age hardening properties after the sample processing stage 1 and m2 distortion and solid solution, and the method of the present invention is an effective processing method for improving heat resistance and strength. I believe it is. Note that the final heat treatment is intended to generate and disperse intermetallic compounds, and has a different purpose from annealing to remove working strain, which is normally performed after cold working.
