Applications
3M 1126 tape 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 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.
