EMI printing metal dome array

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:

Light & small ;

1.Damp proof, heatproof, cold proof ;

2.Dustproof is done on the Metal Dome, and oxygenation of Metal Dome has been avoided;

3.There's one layer of Rubber Glue on top of the Mayler or EMI. It has special Plastic performance and can be tightly stick on Keypad or PCBs.
 

Character:

1. Special Plastic performance and tightly stick on Keypad;
2.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 ;

3.With the infiltration of static the effect of protecting the loop happened Manufacturing engineering can be more difficult compared with the exist metal dome;

4. Strong applicability to the changeable climate.
