EMI Shielding

KGS’ EMI shielding materials help with sealing or grounding EMC noise entering or exiting a device. Using shielding can be crucial for long-term reliability of your design. KGS’ shield include a wide variety of products including electrically conductive fabric-over-foam (FoF) gaskets, conductive EZ foams, shielding tapes (copper, embossed copper, aluminum, and conductive fabric), cable shielding jackets (adhesive or Velcro closure), metal mesh tape, and thin conductive films (transparent and non-transparent). Depending on the application, KGS EMI shields can be used alone or in conjunction with another solution material (such as EMI grounding parts or EMI absorbers), typically with double-digit attenuation levels.

Careful design should be considered in order to have the most optimal effects from using shielding materials. For cables, a continuous shielding jacket (rather than segmented pieces connected with conductive tape) is a much more effective and reliable plan. Grounding clamps can be used on both ends to EMC ground the shield for increased shielding effectiveness. Alternatively, metal mesh tape can be used for shielding and grounded by soldering the metal itself.

For displays and apertures, out transparent shielding film is a great way to achieve EMI shielding and provide optical clarity. The shield can be ground around the perimeter to a metal bezel using FoF gaskets, conductive foams, or conductive fabric tapes.

On metal enclosures, conductive tapes are a commonly used during EMC testing. FoF gaskets and conductive foams are also very effective. It is one of the easiest solutions to apply gasketing along the entire perimeter to prevent any slit antennas.
