Silicone Rubber Backlight Keypad: That have some ways to process the backlight silicone keypads.
1. Laser Etched Silicone Keypad. Firstly, Do Printed Ink Process, the printed ink color is same to the laser etched legends, and then spray coating on the surface the silicone rubber keypad. Lastly place the keypads on the laser etched machines for process.
Notes: The legends color should have a high contrast with the spray coating color
Like following case: The legends color is translucent, and the spray coated color is gray.
2. Translucent Silicone Backlight Keypad
1.) Translucent Silicone Backlight Keypadtake full advantage of silicone original materials which is translucent. Different silicone is different transparency. Generally, more better silicone materials, the color is more transparent. The original color of liquid silicone is almost transparent.
That have two different translucent backlight Silicone Keypad: The first one is more transparent: The one make cover tool to protect the translucent parts and then dotwo layers sprayer coating. The Second is less transparent, which choose mixed color process way.
2.) Silk Screen Translucent Silicone Backlight Keypad, generally, need spray painted before do font or symbol printing on the surface, and the do PU coating process to protect the legends. However, Silk Screen Translucent Silicone Backlight Keypad, which needn't do spray coating process. For better backlight legends effects, sometimes, also needn't do PU coating or UV+PU coating.
Knowledge: The light source of Plastic Backlit Keyboard is different the backlight which light source behind LCD.
1. Offer 2D, 3D design (PDF, CAD, STEP, IGS, slprt. ) drawings, or samples 2. Include number of legend and silicone colors, Of need silicone light guide. 3. With or without carbon pills 4. Keypads surface demands: Laser Etched, Silkscreen, Spray Coating, UV Coating etc. 5. Quantities to be quoted
These are the primary elements for a quotation. Other details such as travel, force, durometer and tactile response can be determined at the time of order.Specialty features such as protective coatings, laser etching, light pipes, etc. should be included.
