EMI Shielding Tape with
Conductive Adhesive (2800 Series)
Tapes are an economical EMI shielding solution for a variety of commercial uses. The tapes are available in copper or aluminum backed with conductive pressure-sensitive adhesives. Copper tape meets the requirements of MIL-T-47012 for corrosion resistance. Typical properties are shown in Table 1.
Copper tape is available with a non-conductive adhesive for applications requiring surface conductivity only. Standard length rolls and die-cut custom shapes can be ordered. Other types of shielding tape are available by request.
Typical Applications for Shielding Tapes
Provide a low impedance connection between a braided cable shield and the metal connector backshell in molded cables. An effective EMI-shielded assembly can be achieved without soldering the tape to the braid or backshell.
EMI radiation measurement trouble-shooting, using tape to shield ventilation slots or seam gaps.
Provide electrical continuity in seams of EMI shielding rooms and electronic enclosures.
Supply electrical contact to surfaces that can’t be soldered,
such as conductive plastic or aluminum.
Provide EMI shielding for cables when tape is wrapped around
the cable. (An overlap is recommended.)
Provide ESD shielding.
Provide corrosion-resistant ground contact points.
Fabric tape available where weight and flexibility are important, such as for wrapping cables.
