fabric shielding gaskets High-Performance EMI Fabric Shielding Gaskets Leader Tech EMI Fabric Shielding Gaskets 1 Introduction Fabric Shielding Gaskets EMI Shielding Gaskets for Electronic Enclosures Shielding gaskets are, very simply, connectors of two opposing metallic planes which make them appear as one continuous surface, by connecting across the openings. Depending on the frequencies involved, the openings must be reduced as closely as possible to a continuous seal. Typical EMI Fabric Shielding Gasket electronic enclosure installation. Leader Tech's unique Fabric Shielding Gasket structure is a combination of a highly conductive nickel/copper ripstop fabric and a resilient polyurethane foam core. Leader Tech's FSG products have superior shielding properties and ensure long performance life all in a cost effective manner. Benefits of Fabric Shielding Gaskets (FSG) * * * * * * * * * * * 2 Excellent shielding effectiveness Extremely low compression force allows for use of lighter materials and less fastening and hinge hardware Low Surface Resistivity provides excellent conductivity Abrasion resistant metalized fabric for durable performance Low compression set ensures long term reliability of gasket performance Profile and I/O gaskets are available with PSA tapes which facilitates quick assembly Designed for use with non-conductive pressure sensitive adhesive for better adhesion FSG products can be ordered from 24" or 48" stock, cut to specific lengths or kiss cut on release liner Over 100 sizes to choose from in a variety of profiles Many profiles can be mitered and bonded as a frame gasket Prototype samples can be provided within 24 hours Phone: 1.866.Tech.EMI Fax: 813.855.3291 Web: www.leadertechinc.com Fabric Shielding Gaskets assure tight EMI electrical contact sealing of electronic enclosures with high speed microprocessors.

Absorption depends on the thickness of the shield material. However, reflection occurs at the shield surface and its effectiveness is independent of thickness. Reflection is the determining factor for all high frequency signal attenuation. (Note: When using these materials for conductive shielding gaskets, conductivity is the determinant.) Maximum reflection occurs with the highest conductivity materials - the best being copper, nickel and combinations of both. Options * All materials are available in non-adhesive, hot melt or conductive adhesive backing * Standard sheets are 41" x 36" (1041 x 914 mm) * Longer lengths can be custom ordered - please consult factory for information * Full rolls are 325' (99M) long - please consult factory for ordering information. Note: conductive adhesive versions are 164' (50M) long Applications Bonding or laminating to complex geometric shapes with optional hot melt or conductive adhesive. * Large surface coverage with minimal seams due to 41" material width * ESD/RFI-EMI shielding attenuation > 70dB up to 10 GHz for CuNi type * Seal enclosure panels and frames, seams or joints * Use for architectural shielding or shielded room wall and ceiling finishing Part Number w/o Adhesive w/Hot Melt Adhesive SF005PCN SF005PCN-HM SF030PCU SF030PCU-HM SF050PNI SF050PNI-HM w/Conductive Adhesive Description Width Length CuNi 41 1041 36 SF005PCN-CA Conductive Cloth Cu 41 1041 36 SF030PCU-CA Conductive Cloth Ni 41 1041 36 SF050PNI-CA Conductive Cloth Thickness Surface Resistivity 500KHz 100MHz 300MHz 1GHz 914 0.003 0.08 .005 ohm/mm2 79dB 81dB 86dB 82dB 914 0.003 0.08 .035 ohm/mm2 60dB 67dB 65dB 62dB 914 0.004 0.10 .050 ohm/mm2 60dB 72dB 67dB 63dB FABRIC SHIELDING TAPES Applications Cable shielding, enclosure seams, shielded room joints, PCB component shields, irregular surface/component shields, alternative to custom die-cut shielding gaskets or sections. * Service Temperature: -40F to 212F (-40C to 100C) * Adhesion: (peel) 50 oz/in.
