Applications
■ 3M Copper Foil Tape 1181 is typically used as an EMI/RFI shielding tape for applications in the electronics industry such as static charge draining, seaming 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 1181 Tape is >85dB, 1MHz to 2 GHz, ASTMD-4935 test method..
