Electrically Conductive Tapes & Films
Contact UsFrom simple to complex designs, 3M™ Electrically Conductive Tapes and 3M™ Electrically Conductive Films are designed for electromagnetic interference (EMI) shielding and grounding applications, enabling devices to meet electromagnetic compatibility requirements. These electrically conductive pressure sensitive adhesive (CPSA) tapes and electrically conductive films provide excellent adhesion to a variety of substrates including metals and plastics.
Selection Criteria for Electrically Conductive Tapes & Films:
Selecting a Electrically Conductive Tape or Film for grounding, shielding, and attachment includes identifying several application requirements. For instance, the selection process could take the following items into consideration, among others:
1. Contact R target
2. Contact surface type
3. Adhesion level desired
4. Bond line thickness
5. Z or XYZ conductivity path
6. Operating temperature range and environmental conditions
7. EMI shielding in bond line “Gap/ Slit” for higher frequencies
8. Surface contact area for adhesion
9. Assembly pressure, temperature and time
