Many factors can affect the actual effect of EMI/RFI shielding tape after application, such as the type and thickness of the foil, the type of adhesive, the tightness of the contact, the smoothness of the application surface, the strength and frequency signal of EMI/RFI, etc. Standard testing and fixed devices can still be used to determine attenuation values. Copper foil tape has excellent conductivity and provides electromagnetic shielding effect. It…
