Silicone backlit keyboards have become essential components in a wide range of electronic devices, offering flexibility, durability, and an enhanced user experience. Constructed from high-elastic silicone rubber, these keyboards can be customized with various legends and patterns to meet specific aesthetic and functional requirements. This post will outline the manufacturing process of silicone backlit keyboards and highlight the advantages of working with Flykeyboard, a leader in this industry.
Understanding Silicone Backlit Keyboards
Silicone backlit keyboards provide not only tactile feedback but also visual appeal, making them suitable for various applications, from consumer electronics to medical devices. The key advantages include waterproofing, easy cleaning, and the ability to incorporate different designs and colors.
Manufacturing Process of Silicone Backlit Keyboards
The production of silicone backlit keyboards involves several critical steps:
Step One: Creating the Transparent Silicone Base
The process begins with compression molding to produce a transparent silicone base. This involves placing silicone rubber into a mold, where heat and pressure are applied to shape it into the desired form. The result is a durable and flexible base that serves as the foundation for the keyboard.
Step Two: Applying Base Coatings
After forming the silicone base, the next step is to apply a white and black spray coating. This dual-layer approach is essential for creating the visual effects required for backlit keyboards. The white base provides a backdrop for the legends and ensures optimal light diffusion.
Step Three: Laser Engraving
Once the spraying is complete, the silicone keypad is positioned on a laser engraving machine. Desired characters and patterns are imported into the machine, which then precisely removes the black spray to expose the white characters beneath. This step is crucial for achieving accurate legends and enhancing the keyboard’s aesthetic appeal.
Step Four: Silkscreen Printing
Following the laser engraving, silkscreen printing is employed to reinforce the white characters. This additional layer of ink ensures that the legends remain visible and durable throughout the keyboard’s lifespan.
Step Five: Protective Coating Application
To enhance durability and protect the surface legends, a protective coating—such as polyurethane (PU)—is applied. This coating helps prevent wear and tear, ensuring that the keyboard maintains its appearance and functionality over time.
Manufacturing Tips for Optimal Results
- Spraying Consistency: Uneven spraying can lead to light leakage. It’s advisable to increase the spraying time to create a thicker coating, while also ensuring that the sides of the buttons are evenly coated.
- Laser Etching Brightness: During the laser etching process, the removal of white ink can affect brightness. It is crucial to reduce the strength of the laser and conduct tests to ensure optimal brightness before proceeding with the formal etching.
- Coating Thickness: A thin coating may result in a reduced lifespan for the keyboard. Increasing the number of spraying layers can significantly improve durability.
Frequently Asked Questions
Q: Does color spraying affect the actuation force of silicone backlit keyboards?
A: Yes, the actuation force can increase significantly after the color spraying process. For example, if a keyboard is designed for an actuation force of 150g, the actual force may rise to 250g ± 80g due to the added thickness from the spray coating. This increase can impact the overall feel and responsiveness of the keys.
