Metal Dome Rubber Glue Dome Array

Rubber Glue Dome Array

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. Because material of adhesive is Silicone, so it also named Silicon or Acrylic PSA adhesive tape.


Special Plastic performance and tightly stick on Keypad

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
