Copper tape is a kind of metal tape, which is mainly used for electromagnetic shielding, electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly depends on the excellent conductivity of copper itself, while magnetic shielding requires the conductive material "nickel" on the adhesive surface of copper tape to achieve the function of magnetic shielding, so it is widely used in mobile phones, laptops and other digital products.

1. The test conditions are normal temperature 25 ℃, and the relative humidity below 65 ℃. The test results of ASTMD-1000 are used.
2. When the goods are stored, please keep the room dry and ventilated. The storage time of domestic copper is generally 6 months, and the import country can keep it longer and not easy to oxidize
3. The product is mainly used to eliminate electromagnetic interference EMI and isolate the harm of electromagnetic wave to human body. It is mainly used in the manufacturers of computer peripheral wire, computer monitor and transformer.
4. Copper tape is divided into single-sided adhesive tape and double-sided adhesive tape. The single-sided adhesive coated copper tape is also divided into single conductive copper tape and double conductive copper tape. The single conductive copper tape means that the adhesive coated side is not conductive, and only the other side is conductive, so it is called single conductive copper tape; Double conductive copper foil tape refers to the conductive surface of the adhesive coating, and the copper on the other side is also conductive, so it is called double conductive, that is, double conductive. In addition, double-sided adhesive coated copper foil tape is used to process expensive composite materials with other materials. The adhesive surface of double-sided adhesive coated copper foil can also be divided into conductive and non-conductive. Customers can choose according to their own conductive needs.
