Copper foil tape is a kind of metal tape, mainly used in electromagnetic shielding, magnetic signal shielding and electrical signal shielding. Electrical signal shielding mainly relies on the excellent conductivity of copper itself, while magnetic shielding requires copper foil tape. Surface conductive material "nickel" to achieve the effect of magnetic shielding, so it is widely used in mobile phones, notebook computers and other digital products.
Product description of copper foil tape
The purity is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic waves to the human body, and avoid unnecessary voltage and current to affect the function. In addition, it has a good effect on electrostatic discharge after grounding. It has strong adhesive force and good electrical conductivity, and can be cut into various specifications according to customer requirements.
The use of copper foil tape
It is suitable for all kinds of transformers, mobile phones, computers, PDPs, LCDs, PDA monitors, notebook computers, copiers and other electronic products where electromagnetic shielding is required.
