Common EMI/RFI materials

Common EMI/RFI materials are:

(1) Metal foil tape: Relatively easy to manufacture. The use of aluminum foil and copper foil backing tape provides excellent shielding performance without expensive metal plating on the case.

(2) Metal filled rubber: These materials are suitable for shielding applications that require gap filling and shock absorption.

(3) Metal wire mesh: Mainly used for EMI gaskets. The heat dissipation effect of the wire mesh material is better than that of metal foil, but it is heavier and takes up more space.
