EMI Shielding Tape With Adhesive

Series No. 2800

MAJR Products’ EMI shielding tape, also known as copper tape or foil tape, offers 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. Both standard length rolls and die-cut custom shapes can be ordered. Other types of shielding tape are available upon request.

Applications

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.
