Copper foil tape is a kind of metal tape, mainly used in electromagnetic shielding, electrical distribution signal shielding and magnetic signal shielding. Electrical signal shielding mainly relies on the excellent conductive properties of copper itself, while magnetic shielding requires the conductive substance "nickel" on the rubber surface of the copper foil tape to achieve the role of magnetic shielding, so it is widely used in mobile phones, laptops and other digital products.
Product Description: The purity is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the damage of electromagnetic waves to the human body, and avoid the need for voltage and current to affect the function. In addition, it has a good effect on electrostatic discharge after grounding. It has strong adhesion and good conductivity, and can be cut into various specifications according to customer requirements.
Purpose: Suitable for various transformers, mobile phones, computers, PDAs, PDPs, LCD monitors, laptops, copiers and other electronic products that require electromagnetic shielding.
