Air Channels
When the rubber key is combined with the substrate or the keyboard film, it must have the air passage, otherwise when the button operation is performed, air can't be discharged smoothly, affecting the adjacent keys, and it can cause wrong movements or insensitivity, and it will be more elastic and so on.
Press Ribs
Please don't forget that there are ribs inside the button structure. When the silicone button is pressed, the ribs will make each single keyboard operate indenpendntly* Also, it doesn't affect other nearby keyboard, and the elasticity and sensitivity.
Contact Pills
The contact pills 【Silicon rubber and round conductive carbon particles】 can come out under the continuous high temperature vulcanization environment.
The contact pills can be designed in a circular, elliptical, circular or any specific size format as required.
In general, the standard diameter of the conductive carbon particles is 4 mm and the thickness is 0.5 mm. We also offer any diameter sizes that client wants. Other shapes can also be replace with printing conductive agent instead of carbon.
Location Holes
The silicon rubber button must have some specific positioning holes on the substrate or on the plastic case to facilitate assembly and parts without displacement.
Contact Areas
The contact area is designed and soldered by various special applications.
We can offer different methods such as 〝tin-plated, nickel-plated, nickel-plated and gold-plated substrates.〞Also, printed substrate can be used.
Keyboard Protection Against Attrition
Silicon rubber buttons can be rubbed with a layer of paint after printing or laser engraving. This layer can protect printing blur from after using for a long time, and achieves the anti-wear function.
