Copper tape is manufactured by producing high-purity copper foil via electro-deposition or rolling, treating the surface for adhesion, applying a conductive or non-conductive adhesive, and coating it with a liner, followed by slitting into specific widths. It is used for EMI shielding, electrical, and DIY applicationsKey Production Stages
* Copper Foil Creation:
* Electro-deposition: Copper is dissolved in acid and deposited onto a rotating drum to form thin, uniform foil (smooth on one side, rough on the other).
* Rolling: Copper blocks are heated to high temperatures (up to 1000°C) and mechanically rolled into thin sheets.
* Surface Treatment: The foil is treated, cleaned, and annealed to improve ductility, adhesion, and surface brightness, removing impurities and oxidation.
* Adhesive Application: An acrylic or rubber-based adhesive (conductive or non-conductive) is coated onto the foil.
* Lamination and Coating: The adhesive side is covered with a backing liner for protection and stability.
* Slitting and Packaging: The large, finished foil sheets are cut into precise, smaller rolls for end-use
