EMI Shielding Copper Foil Tape Features

Electromagnetic shielding performance: can effectively eliminate electromagnetic interference (EMI), isolation of electromagnetic wave damage to the human body, divided into electrical signal shielding and magnetic signal shielding, electrical signal shielding rely on the electrical conductivity of copper, magnetic shielding with the aid of the adhesive surface of the “nickel” and other conductive substances.
Conductive properties: can realize good grounding and static discharge, provide stable electrical connection for electronic products, reduce interference and loss in the signal transmission process.
Physical properties: strong adhesive force, can be firmly attached to a variety of surfaces; with a certain degree of temperature resistance, generally in the range of - 10 ° C to 120 ° C can be used normally; in addition, also has a good weather resistance, puncture resistance and flexibility.
High Conductivity: Better than aluminum foil tape for low-resistance grounding.
Flexibility: Conforms to curved surfaces and tight spaces.
Easy Application: Peel-and-stick design with good adhesion to plastics, metals, and PCBs.
