Copper tape is a kind of metal tape, is mainly used in electromagnetic shielding, divide into two kinds, signal shielding and magnetic shielding signal shielding mainly depend on the excellent electrical conductivity copper itself, and magnetic shielding requires the adhesive surface of the conductive copper foil tape material "nickel" to achieve the effect of magnetic shielding, and therefore is widely used in mobile phones, laptops and other digital products.The general inspection performance of the most commonly used copper foil tape on the market. we have aluminum foil tape

Common knowledge of copper foil tape 1. Under normal temperature of 25℃ and relative humidity below 65℃, ASTMD-1000 test results are adopted. 2. When the goods are stored, please keep the room dry and ventilated. The domestic copper is generally stored for 6 months, while the importing country can keep it longer and it is not easy to oxidize 3. The products are mainly used to eliminate electromagnetic interference EMI and isolate the harm of electromagnetic wave to human body. They are mainly used in computer peripheral wires, computer monitors and transformer manufacturers. 4. Copper foil tape is divided into single-sided adhesive and double-sided adhesive.Single-sided coated copper foil tape is divided into single-guide copper foil tape and double-guide copper foil tape. Single-guide copper foil tape refers to the coated surface does not conduct electricity, and only the other side of copper conducts electricity, so it is called single-guide or single-side conductive.Dual-conductor copper foil tape refers to the conductive surface of the coating, and the other side of the copper itself is also conductive, so it is called double-conductor or double-sided conductive.There are double-sided coated copper foil tape and other materials used to process into more expensive composite materials, double-sided coated copper foil its adhesive surface is also divided into conductive and non-conductive two.Customers can choose according to their own demand for conductivity.
