Copper foil tape, tape is a kind of metal, mainly used in electromagnetic shielding, divide into two kinds, signal shielding
and magnetic shielding signal shielding mainly depend on the excellent electrical conductivity copper itself, and magnetic
shielding requires the adhesive surface of the conductive copper foil tape material "nickel" to achieve the effect of magnetic
shielding, and therefore is widely used in mobile phones, laptops and other digital products.
