Shielding tapes are able to contain signals
Economical EMI shielding
emitted from your components, thus
preventing interference with other circuits.
They can also be used to seal out random
signals in the environment to protect
sensitive equipment. Typical applications
include shielding around electronic cabinet
doors and panels, individual electronic
components and cables. The ease of
installation offered by the pressure-
sensitive adhesive saves labor and provides
cost-effective, long-term shielding.
EMI troubleshooting
3M shielding tapes also simplify the trial-
and prototyping
and-error aspect of EMI troubleshooting.
When a source of EMI leakage is located,
shielding tape easily and effectively solves
