Data Sheet
Product Description
3M
1125 Tape consists of a 1-ounce rolled
copper foil with an acrylic, pressure-sensitive
adhesive.
• 1-ounce copper foil backing
• Acrylic adhesive with excellent bond strength
• Supplied on a removable liner for easy handling
and diecutting
• Meets flame spread requirement of UL510
Applications
3M 1125 tape is typically used in a variety of
EMI/RFI shielding applications such as shielding
small electromagnetic components, repair and
modification of printed wiring boards, flat
conductor assemblies, prototype designs,
supplementary shielding of joints and seams and
shielding cable splices.
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.
