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.

Click to view datasheet of one of normal Rubber Glue materail used in our top adhesive metal dome array.

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
  4. Manufacturing engineering can be more difficult compared with the exist Metal Dome
  5. Strong applicability to the changeable climate
