476680 A7 B7___ 五、發明說明（I) 技術頜域 (請先閱讀背面之注音？事項再填寫本頁) 本發明乃關於銅線以及關於用以製造此銅線之方法。 本發明之背景 在傳統之線材拉製過程中，線材係經由拉製模具拉伸 以在拉製時減小線材之截面積。典型上此方法係藉著使線 材在拉製過程中承受表面上之壓縮應力以及沿著中心拉伸 線之張力以完成。此外，適當排列之絞盤也將沿著製程拉 動被拉製之線材呈拉緊之狀態。當應力大於材料的強度時 ，線材將從機器中斷裂。夾雜物、氧化物粒子、孔洞等之 存在將降低線材之局部強度而造成線材之斷裂。 已知即使在高純度之銅線中，亦會有微孔洞與小型之 氧化物夾雜物在材料中，在金屬加工過程中，其會使自己 朝向拉伸線（張力軸）。當這些孔洞聚集在一起或結合時， 其終將達到足夠之大小而使毀壞發生。此現象會限制線材 可以縮小或拉製之大小。當線材之直徑係約0.0008英吋或 52 AWG時，此通常會發生。拉製至較細之尺寸係非常困 難與昂貴的，此係因爲斷裂會發生且通常係不可能的。 經濟部智慧財產局員工消費合作社印製 術語”高度縮減之銅線”係指銅線當承受張力測試時在 斷裂之前，在其截面積上會有高度之縮減。該縮減係以從 原來之截面積至斷裂表面之末端之截面積，其在截面積上 之縮減百分率（％ RIA)來表示。98%可縮減之銅線在斷裂之 前將在其截面積上進行98%之縮減◦ 100%可縮減之銅線係 承受張力測試時可顯示完全之延展斷裂之銅線，此銅線在 張力測試過程中終將斷裂，但其斷裂表面近似針點。具有 4 本紙張尺度適用中國國家標準（CNS)A4規格（210 X 297公釐） 476680 經濟部智慧財產局員工消費合作社印製 A7 B7 五、發明說明（>) 100-600

Description of the invention (I) Technical jaw area (please read the note on the back? Matters before filling out this page) This invention relates to copper wire and the method for manufacturing this copper wire. BACKGROUND OF THE INVENTION In the traditional wire drawing process, the wire is stretched through a drawing die to reduce the cross-sectional area of the wire during drawing. This method is typically accomplished by subjecting the wire to compressive stress on the surface and tension along the center of the wire during drawing. In addition, the properly arranged winches will also pull the drawn wires in a tight state along the process. When the stress is greater than the strength of the material, the wire will break from the machine. The presence of inclusions, oxide particles, holes, etc. will reduce the local strength of the wire and cause the wire to break. It is known that even in high-purity copper wires, there are micro-voids and small oxide inclusions in the material. During metal processing, they will face themselves toward the tensile wire (tension axis). When these holes are gathered or combined, they will eventually reach a sufficient size for destruction to occur. This phenomenon limits the size of the wire that can be reduced or drawn. This usually happens when the diameter of the wire is about 0.0008 inches or 52 AWG. Drawing to finer dimensions is very difficult and expensive because fractures occur and are often impossible. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The term “highly reduced copper wire” means that when a copper wire is subjected to a tensile test, it will have a high reduction in its cross-sectional area before it breaks. The reduction is expressed as a percentage reduction (% RIA) in the cross-sectional area from the original cross-sectional area to the end of the fracture surface. 98% shrinkable copper wire will be 98% reduced in its cross-sectional area before breaking. 100% shrinkable copper wire is a copper wire that can show complete extended fracture when subjected to a tensile test. This copper wire is subjected to a tensile test. The process will eventually break, but the fracture surface is similar to the pin point.

Description of invention (>) Standard electrolysis of 100-600 ppm oxygen Refined (ETP) copper will typically show approximately 80-90% RIA. An oxygen-free wire (OFE) with less than 10 ppm oxygen will typically show an RIA from 90-97%. Ultrapure copper typically shows 95-98% RIA. Until now, the general industrial view was that RIAs greater than 98%, and especially 100% RIAs, were not commercially feasible. The present invention provides a copper wire capable of achieving a RIA greater than 98% and a 100% RIA in a specific embodiment, and a method for manufacturing the copper wire. U.S. Patent No. 5,679,232 discloses a method for manufacturing a metal wire, including: (A) forming a metal foil; (B) cutting the foil to generate at least one strand of the metal wire; and (C) applying The strands of the wire are shaped to provide strands having a desired cross-sectional shape and size. This method is suitable for making copper wires having very fine diameters (e.g., about 0.0002 to about 0.02 inches). Summary of the Invention The present invention relates to a method for manufacturing copper wire from electrolytically deposited copper foil, which has a occluded oxygen content of less than about 200 ppm and can be reduced to greater than 98% during tension testing. RIA, this copper foil is characterized by many twin crystals or stacking errors in its crystal structure. The present invention also relates to a method for manufacturing the aforementioned copper wire, the method comprising: (A) having a copper ion concentration ranging from about 30 to about 120 grams per liter and a free-state sulfuric acid concentration ranging from about 40 to about 120 per liter; G, electrolyte solutions with a chloride ion concentration of less than about 1 ppm, organic additive concentrations of not more than about 1 ppm, and metal impurity levels of less than about 2000 ppm, using about 40 to about 480 amps per square foot (ASF ) The current density range of electrolytic deposition has about 0.0002 inches to about 0.02 5 This paper size is applicable to China National Standard (CNS) A4 specifications (210 X 297 mm) IL ---------- · Install -----.--- Order --------- Line · (Please read the precautions on the back before filling this page) 476680 Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 5 2.

Under the description of the invention (丨 σ), it is believed that the crystal defect structure is directly related to the copper of the present invention. The highly reduced characteristics of the line (ie, RIA higher than 98%) are related. The double crystal or stacking error can be observed using a microscope analysis, a transmission electron microscope (TEM) analysis, or a scanning electron microscope (SEM) analysis. Display In Figures 10-14 are micrographs of copper foil samples from Example 2 at magnifications from 400 to 50,000. In each example, 'large twin crystals or stacking errors are shown in the crystal structure of the copper foil It is also important that the electrolytically deposited copper foil or copper wire has not undergone melting during the method for manufacturing a copper wire of the present invention. Once again, I do not want to be limited by any theory, I believe that this melting will tend to destroy the crystal Double crystals or stacking errors in the structure. This crystal The destruction of the defective structure will destroy the highly shrinkable nature of the copper wire of the present invention (ie, RIA above 98%). Therefore, it is important that the cutting and shaping steps of the method of the present invention be performed at a temperature below the melting point of the copper being processed. Electrolytically deposited copper foil is manufactured in an electroformed cell equipped with a cathode and an anode. The cathode can be installed vertically or horizontally and in the form of a cylindrical mandrel. The anode is adjacent to the cathode and has a bend with the cathode The curved shape is consistent to provide a uniform gap between the anode and the cathode. The gap between the anode and the cathode is usually measured from about 0.3 to about 2 cm. In a specific embodiment, the anode is insoluble and consists of lead, Lead alloys or titanium or its oxides coated with molybdenum group metals (ie, Pt, Pd, Ir, Ru). The cathode has a smooth surface to accept electrolytically deposited copper and in one embodiment, It is made of stainless steel, mineral chromium stainless steel, or titanium.
