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).
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.
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.
Using screen printing polyester foil is printed with a conductive silver lattice. The mesh width can be adjusted. Display and LED windows are omitted.
When it comes to shielding electro-magnetic radiation, pure copper foil may be used. This foil demonstrates better contact and conducts in all directions.
