Why EMI Shielding is Essential for Modern Electronics and Devices

Our EMI shielding solutions offer various conductive fillers that are designed to ensure galvanic compatibility while providing low contact resistance between mating surfaces. Our conductive elastomers are fully cured silicones or fluorosilicone loaded with a variety of highly conductive particles providing superior EMI/RFI shielding performance combined with excellent environmental sealing.

Why is EMI shielding important?

All active electronic devices have the potential to emit electromagnetic radiation. EMI shielding products protect critical electronic components and systems from EMI interference.

EMC compliance required by law/performance specifications
EMC non-compliance causes system level redesign late in product development process

Where is EMI shielding used?

EMI shielding gaskets are applied at the seams of an enclosure to establish a low resistance conductive path to block radiated emissions into and out of the enclosure.

EMI Shielding Application Solution

RFI/EMI shielding gaskets and components provide exceptional EMC shielding solutions to address regulatory compliance and performance needs. Our shielding solutions include electrically conductive gaskets, EMI shielding ventilation panels, shielded window, cable shielding and shielding components.

Clip on knitted wire mesh: Clip on knitted wire mesh gasket strip is a very flexible, easily compressible sponge EPDM tubular or bulb type gasket strip with a steel spring clip covered with a double knitted wire mesh layer for RFI / EMI shielding. Most suited for enclosure / cabinet door applications.

Electrically Conductive Adhesives: Our line of electrically conductive adhesives provides RFI/EMI shielding and grounding solutions. They consist of a densely loaded adhesive filled with electrically conductive particles to make a strong and effective conductive glue.

Conductive Fabric over foam gaskets: Highly conductive nickel/copper or silver-plated polyester or nylon fabric over an open celled urethane core. Many profiles are available including rectangular, D shape and low compression/deflection C shape seals, half wrap and fabricated gaskets.

Conductive Foam: Conductive foam is a low-density polyethylene terephthalate (PET) and polyurethane foam

Form in Place Gasket: Electrically conductive or non-conductive silicone elastomer compounds are deposited as a gasket directly to the enclosure by XYZ CNC technology.

Beryllium Copper Fingers: Beryllium copper (BeCu) spring finger stocks and contact gaskets are manufactured by punching or etching thin BeCu strip which is pressed and formed into the required final shape and then heat treated to give it ‘memory’.

Conductive Adhesive Tape: Electrically conductive tape is available in copper, tinned copper or aluminum, an electrically conductive adhesive is applied to the foil.

PCB Spring Contacts: Spring finger contacts (also known as shield fingers, grounding springs, universal ground contacts, or clips) can be used in all types of small printed circuit board applications across all industries.
