Topic: Plasma activation and coating on silicone key pads. Pretreating conductive rubber
Strong Adhesion, even on Non-Polar Material Potential-Free Pre-Treatment of Silicone Key Pads
are an essential element in every computer, mobile telephone or
remote control keyboard, yet they are made of materials with low
wettability, such as silicone and conductive rubber. During
manufacturing, a conductive film is applied so that, when the keys
that lie on top of that layer are touched, the necessary contact is
established between them and the printed circuit board.
Optimal adhesion of printed coatings on telephone key pads
Openair® Plasma treatment for improved conductivity
plasma activation creates optimal preconditions for the coating
applied during the printing process, and at the same time the higher
surface energy means that the material’s electrical conductivity is
significantly increased as well.
