Copper foil tape is a kind of metal tape. It is mainly used in electromagnetic shielding. It is divided into two types: electrical signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while magnetic shielding requires copper foil tape. Surface conductive material "Nickel" is used to achieve the effect of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products.
Product Introduction:
Product description: The purity is higher than 99.95%. Its function is to eliminate electromagnetic (EMI) interference, isolate electromagnetic waves from harming the human body, and avoid unnecessary voltage and current from affecting functions. In addition, it has a good effect on static electricity discharge after grounding. It has strong adhesive force and good electrical conductivity, and can be cut into various specifications according to customer requirements.
Uses: Suitable for all kinds of transformers, mobile phones, computers, PDAs, PDPs, LCD monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.
It is a kind of metal tape, mainly used in electromagnetic shielding, divided into two types: electric signal shielding and magnetic signal shielding. The electric signal shielding mainly relies on the excellent electrical conductivity of copper itself, while the magnetic shielding requires the conductive material of the rubber surface of the copper foil tape" Nickel" is used to achieve the effect of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products. The general inspection performance of the most commonly used copper foil tape on the market is as follows: Material: CU 99.98%

Peel force: 0.2~1.5kgf/25mm (180-degree reverse peel force test)
Temperature resistance -10℃---120℃
Tensile strength 4.5~4.8kg/mm
Elongation 7%~10%MIN
Common sense of copper foil tape
1. The test conditions are normal temperature 25°C and relative humidity below 65°C, using the test results of American ASTMD-1000.
2. When storing the goods, please keep the room dry and ventilated. The domestic copper is generally stored for 6 months, and the importing country can store it for a longer period of time and is not easy to oxidize.
3. The product is mainly used to eliminate electromagnetic interference EMI and isolate the harm of electromagnetic waves to the human body. It is mainly used in manufacturers of computer peripheral wires, computer monitors and transformers.
4. Copper foil tape is divided into single-sided adhesive and double-sided adhesive. Copper foil tape covered with glue on one side is further divided into single-conductor copper foil tape and double-conductor copper foil tape. Single-conductor copper foil tape means that the glue-covered surface is non-conductive, and only the other side is copper-conductive, so it is called single-conductor, that is, one-sided conduction. ;Double-lead copper foil tape means that the rubber-covered surface is conductive, and the copper itself on the other side is also conductive, so it is called double-conductor, that is, double-sided conductive. There are also double-sided adhesive-coated copper foil tapes that are used to process with other materials into relatively expensive composite materials. The double-sided adhesive-coated copper foils also have two types of conductive and non-conductive adhesive surfaces. Customers can choose according to their own needs for electrical conductivity.
