Copper Foil Tape Product Introduction

- Oct 11, 2019-

Product description: the purity is higher than 99.95%, and its function is to eliminate electromagnetic (EMI) interference, isolate the harm of electromagnetic wave to human body, and avoid affecting the function without the need of voltage and current. In addition, it has good effect on electrostatic discharge after grounding. Strong adhesion, good electrical conductivity, according to customer requirements can be cut into various specifications.

Application: suitable for electromagnetic shielding of various electronic products such as transformer, mobile phone, computer, PDA, PDP, LCD display, laptop, copier, etc.

Is a kind of metal tape, is 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. Currently, the most commonly used copper foil tape on the market has the following general inspection performance: material: CU 99.98%
