Self-Adhesive EMI RF Shielding Copper Foil Tape with Conductive
Copper Tapes Product Detail:
Many EMI problems can be solved easily with Mu-copper foil or tape. Mu-copper tape is available with or without (conductive) self-adhesive and an optional insulation layer.
When large surfaces are to be shielded, it is recommended to cover most of the surface with Mu-copper foil, possibly in combination with tape with a conductive self-adhesive. This solution is much cheaper than covering the entire surface with tape strips.
Mu-copper tape can also be delivered as die-cut, according to your drawing, on strips or in pieces (as stickers), with optional self-adhesive.
Applications:
EMI shielding tape/gasket
Shielding of all non-conductive materials Ground plane
Shielding in housings and Faraday cages
Temporary shielding during tests
Mounting transparent foils and windows for EMI/RFI shielding
Cable shielding (tape wrapped around cable)
Many factors influence the actual effectiveness of an EMI/RFI shielding tape after it has been applied, such as the type and thickness of foil, type of adhesive, closeness of contact, smoothness of application surface, strength, and frequency of the EMI/RFI signal, etc. Still, attenuation values can be determined using standard tests and fixtures.
For EMI/RFI shielding tape, typical shielding effectiveness (far field) is in the range of 60dB to 80dB (10 kHz to 20 GHz).
