-
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: |
- Light & small
- Damp proof, heatproof, cold proof
- Dustproof is done on the Metal Dome, and oxygenation of Metal Dome has been avoided
