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