requirements<\/strong>\uff1aUse high-purity electrolytic copper (\u226599.99%) as raw material to ensure material conductivity and processability.<\/li>\n<li><strong>Blank preparation<\/strong>: Copper blanks are prepared by casting or hot rolling process, and the thickness is usually 10-15mm.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Rough rolling<\/strong>\n<ul>\n<li>The copper blank is gradually thinned to about 3 mm through multiple rolling passes.<\/li>\n<li>Use emulsion lubrication to ensure material cooling and lubrication, the concentration is usually 2%-5%.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Cleaning<\/strong>\n<ul>\n<li>Degreasing and cleaning: remove the oil stains attached during the rolling process.<\/li>\n<li>Pickling: remove the oxide scale to ensure the surface of the copper strip is smooth.<\/li>\n<li>Passivation: Improve antioxidant properties and extend product storage time.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Medium rolling<\/strong>\n<ul>\n<li>Intermediate thickness rolling: The copper strip after rough rolling is further thinned to about 1mm.<\/li>\n<li>Process characteristics:\n<ul>\n<li>Speed: 3-6m\/s (adjusted according to rolling oil or emulsion).<\/li>\n<li>Control focus: plate quality and thickness uniformity.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>Finishing<\/strong>\n<ul>\n<li>The final stage of sizing is to process the copper strip to its final thickness (e.g. 0.05 mm).<\/li>\n<li><strong>Technical requirements<\/strong>:\n<ul>\n<li>Control thickness tolerance within \u00b10.002mm.<\/li>\n<li>Fast speed (6-8m\/s), using high-performance rolling oil.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<li><strong>Annealing<\/strong>\n<ul>\n<li><strong>Purpose<\/strong>: Eliminate internal stress and improve the ductility and tensile properties of the copper strip.<\/li>\n<li><strong>Process parameters<\/strong>: The temperature is controlled at 400\u2103-600\u2103, and the atmosphere is neutral or slightly reducing.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Surface treatment<\/strong>\n<ul>\n<li>Electroplating process: Tin plating, nickel plating and other treatments are carried out as required to improve corrosion resistance.<\/li>\n<li>Polishing process: ensure the copper strip surface is smooth and flawless.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Slitting and packaging<\/strong>\n<ul>\n<li><strong>Striping<\/strong>: Cutting width according to customer needs, with accuracy controlled within \u00b10.01mm.<\/li>\n<li><strong>Package<\/strong>:\n<ul>\n<li>Moisture-proof and anti-oxidation packaging.<\/li>\n<li>Use vacuum packaging or rust-proof paper to ensure transportation and storage
