EMI CONDUCTIVE LAYER SHIELDING
EMI shielded cover glass with a conductive transparent coating is a good solution for use in EMI/RFI shielding application requiring moderate shielding effectiveness and high quality optical properties.
The glass substrate can be replaced by PMMA substrate. Each option offers pross & cons.
The EMI ITO substrate is a highly conductive optical PET film ( Polyester or polyethylene terephthalate ).
Standard shielding options are between 4 to 8 & 15 ohms/sq.
PET thickness starts from 50 µm.
Coatings greater than 20 ohms/sq lack shielding effectiveness and lower ohm/sq coatings have greatly reduced light transmission and increased light reflection.
the advantages of the new conductive layers, are high flexibility and superior optical transparency
ADR offers all those options, together with touch, heater and other layers, through our facilities in Taiwan.
