Gold-plated copper foilFeaturing high-end EMI shielding, RF tuning, conductivity, thermal conductivity, oxidation resistance, and EMI electromagnetic shielding for ultra-fine and ultra-thin wires used in precision electronics and medical equipment.
Copper foil is a type of negative electrolytic material, which is a thin, continuous metal foil deposited on the substrate layer of a circuit board. It serves as the conductor of the PCB. It is easy to adhere to the insulation layer, accept printed protective layers, and form circuit patterns after corrosion. Copper foil has low surface oxygen properties and can adhere to various substrates such as metals, insulation materials, etc., with a wide temperature range of use. Mainly used for electromagnetic shielding and anti-static, placing conductive copper foil on the substrate surface and combining it with metal substrate, it has excellent conductivity and provides electromagnetic shielding effect.
Copper foil is usually in a rolled structure during use. Improper storage after use can easily lead to loose copper foil rolls. Loose copper foil is not only inconvenient to carry, but also prone to damage.
A ultra-thin high conductivity gold-plated copper foil, comprising a winding frame and a copper foil body wrapped around the outside of the winding frame. The copper foil body is provided with vertical plates on both sides, and the top of the two vertical plates is connected to a fixed frame. The inner side of the fixed frame is provided with a first rotating roller, the top of the fixed frame is provided with a movable frame, and the inner side of the movable frame is provided with a second rotating roller. A telescopic component is connected between the fixed frame and the movable frame.
Metal coated copper foil, aluminum foil, and stainless steel foil can be used for single-sided, single double, and different surface coatings with thicknesses ranging from 0.0045 μ m to 300 μ m. This product is widely used in high-end precision industries such as aerospace, communication, mobile phones, medical equipment, and demagnetization. It is lightweight, small in size, highly conductive, heat-resistant, oxidation resistant, and has high weldability. Gold plated copper foil, aluminum foil, and stainless steel foil rolls can be freely cut according to product size to meet various product needs The company aims to specialize in producing ultrafine and micro precious metal composite and alloy materials
Gold is a metallic element with the chemical symbol Au and an atomic number of 79.
Commonly known as gold, it is a widely popular precious metal that has been used as currency, a store of value, and jewelry for many centuries. In nature, gold appears in the form of elemental gold in the form of gold nuggets or grains in rocks, underground veins, and alluvial deposits. Gold is also one of the monetary metals. Gold is a solid at room temperature, with high density, softness, brightness, and corrosion resistance. It is the most ductile metal, second only to platinum, and is one of the most ductile metals.
Gold is a transition metal that can form trivalent and monovalent cations upon dissolution. Gold does not undergo chemical reactions with most chemicals, but can be corroded by chlorine, fluorine, aqua regia, and cyanide. Gold can be dissolved by mercury to form mercury amalgam (but this is not a chemical reaction); Nitric acid, which can dissolve silver and alkali metals, cannot dissolve gold. The above two properties form the basis of gold refining technology, known as "segregation" and "gold silver separation", respectively
