Application Profile

Market: Electronics

Application Description: EMI/RFI shielding of seams and apertures.

Key Application Requirements

Effective, economical shielding of seams and apertures in many shielded rooms. (First determine if a moderate level of shielding will work and if roll goods or die-cuts are preferred.)

EMI = Electromagnetic Interference: Any undesired disturbance, either radiated or conducted, that degrades the proper operations of electrical or electronic equipment. EMI occurs when the operating frequency of one device overlaps that of another. Shields, like metals or metal foil tapes, block radiated energy and keep signals either inside or out.

RFI = Radio Frequency Interference: EMI that occurs in those frequency bands occupied by the majority of radio and other communication signals.

Benefits/Advantages To Customer

Application: Linered tapes are faster and easier to apply than many other typical shielding materials.

Die-cuts: Linered tapes allow precise die-cuts for difficult shielding operations.

Aluminum foil backing: Durable, chemically resistant, electrically conductive backing provides shielding for electrical interference.

Acrylic adhesive: A long-life permanent adhesive.

EMI/RFI shielding: These tapes provide a moderate (25 db at 100 MHz) shielding effectiveness.
