shielded rooms, cable wrapping and surface contact to non-solderable materials.
Shielding
Effectiveness
Many factors determine true shielding effectiveness of a shielding tape, including
type and thickness of foil, adhesive type, intimacy of contact, smoothness of
application surface, frequency of the EMI signal, etc. Typical shielding
effectiveness for 1170 Tape is >85dB, 1MHz to 2 GHz, ASTMD-4935 test
method.
