Applications
3M 1345 Tape is typically used for
applications requiring excellent electrical
conductivity from the application substrate
through the adhesive to the foil backing.
Common uses include grounding and EMI
shielding in equipment, components, shielded
rooms, etc. The tin plating on the copper foil
backing facilitates soldering and improves
resistance to oxidation and discoloration.
Shielding Effectiveness
Many factors determine the true shielding
effectiveness of a shielding tape, including
type and thickness of foil, adhesive type,
intimacy of contact, smoothness of application
surface, strength and frequency of the EMI
signal, etc. However, using standard tests and
fixtures, it is possible to determine a value for
the attenuation.
effectiveness (far field) is in the range of 75dB
to 95dB (30 MHz to 1 GHz).
