Product Description

The purity of copper foil is higher than 99.95%, and its function is to eliminate electromagnetic(EMI) interference, isolationof electromagnetic waves onthe human body injury,avoid unwanted voltage and current without affecting functionality.

In addition,electrostatic discharge after the ground has a good effect.Paste strong,good electrical properties, according to customer requirements cut into a variety ofspecifications.

Application

Suitable for all kinds of transformers, mobile phones, computers, PDA, PDP, LCD monitors, notebook computers, photocopiers and other electronic products where domestic electromagnetic shielding.

The copper foil tape Is a metal tape, mainly used in electromagnetic shielding,that is electrical shielding and magnetic signals of shielded two kinds, Electrical shielding mainly rely on conductive properties of copper itself,which is excellent, But magnetic shielding foil rely on conductive substance "Nickel ", which is on the surface of acrylic adhesive,to achieve magnetic shielding effect.Copper foil tape is widely used in mobile phones, notebook computers and other digital products. Currently on the market most commonly used copper foil tape general test performance are as follows: copper foil tape
