Shielding foils
Shielding to protect against EMI and ESD
The performance of electronic appliances can be impaired by electro-magnetic interference or static charges. We manufacture shielding foils to prevent electro-magnetic interference (EMI) and electro-static discharge (ESD).
Membrane keyboard shielding
Polyester foil with copper or aluminium coating
The specially-coated foil is cut to customer requirements and fitted with openings. It shields over the entire surface and is embedded under the design foil of the foil keyboard.
Shielding of window areas with transparent ITO foil
The window area of a foil keyboard needs to remain transparent for the displays and underlying indicators, so it cannot be protected by the above-mentioned shielding foils. In order to protect this window area, we use an ITO foil (indium/tin oxide-coated foil). It is possible to combine ITO shielding with the above-mentioned shielding foils.
Polyester foil with lattice printing made of conductive silver
Using screen printing polyester foil is printed with a conductive silver lattice. The mesh width can be adjusted. Display and LED windows are omitted.
Pure copper foil
When it comes to shielding electro-magnetic radiation, pure copper foil may be used. This foil demonstrates better contact and conducts in all directions.
