On top of the Mayler which carries metal dome contacts, silver paste or silver carbon paste is printed as ESD (Electrostatic Discharge Control). This helps reduce electrostatic which might be harmful to other parts inside of mobile phones. Electrostatic is gathered on the printed silver paste or silver carbon paste and neutralized.
EMI Single layer
-- EMI is printed on top of single-layer metal dome arrays (dome arrays)
EMI Double layer
-- EMI is printed on top of double-layer metal dome arrays (dome arrays)
Character of EMI dome array
EMI printing has been adopted on current Metal Dome switch, and the priority of EMI printing lies in controlling the impedance of printing surface below 1.0, which result in effect of prevention to Hertzian waves and electrometer, in this way, the tone can be dealt with on the surface.
With the infiltration of static the effect of protecting the loop happened
Manufacturing engineering can be more difficult compared with the exist Metal Dome
Strong applicability to the changeable climate
