When developing a new product that integrates silicone rubber buttons, it is crucial to grasp the intricate design considerations involved. Recently, a long-standing client from France approached us with a project that required finalizing the design of a silicone rubber button pad. Over the years, our collaboration has yielded numerous customized silicone rubber keyboards tailored to their specific requirements. This latest project presented unique challenges that informed our design strategy.
Project Specifications
The silicone rubber button pad needed to fulfill several essential criteria:
– Translucent Silicone: This feature allows for backlighting effects, enhancing the keyboard’s visual appeal and functionality in low-light environments.
– Circular Carbon Contact Points: This design ensures reliable electrical conductivity for each button.
– Cavities for LED Integration: Each button pad required a dedicated cavity to house an LED, thereby improving the keyboard’s illumination capabilities.
In light of these specifications, our design process had to adapt to exclude traditional silkscreen printing legends or laser-etched characters. Instead, we focused on developing an electrically conductive silicone button setup compatible with LED lighting.
Key Design Steps
-
Determining Key Webbing and Actuation Force
The first step in crafting a tactile keyboard involves defining the key webbing to achieve the desired actuation force. Due to space constraints inherent in this client’s design, incorporating adequate key webbing proved challenging. After discussions with the client, our engineering team suggested increasing the outer diameter of the buttons by 5mm. This adjustment resulted in an actuation force ranging from 130 to 160 grams, with a rubber keyboard travel distance of 1.2mm. This configuration not only provides a satisfying tactile response for users but also aligns with ergonomic principles to enhance user experience.
-
Implementing Circular Conductive Contacts for LEDs
Incorporating LEDs under the silicone buttons necessitates a reliable method for electrical connectivity. We opted to use conductive ink at the contact points instead of carbon pills. This choice allowed for greater design flexibility, facilitating adaptations as the project evolved. Using conductive ink streamlined the manufacturing process, reducing costs associated with die-cut tooling required for shaping carbon contacts, while ensuring effective conductivity and reliability.
-
Incorporating Air Vent Grooves
To avoid air entrapment between the silicone keypad and the printed circuit board (PCB), it was essential to integrate air vent grooves into our design. These grooves promote proper adhesion between the silicone keypad and the PCB while allowing trapped air to escape during the manufacturing process. This design feature is critical for maintaining the integrity of electrical connections and enhancing the overall reliability of the keyboard.
-
Utilizing Location Pins for LED Alignment
Precision in LED placement is vital for optimal performance. To achieve this, we incorporated three location pins, each measuring 2mm in diameter, on the rubber button pad. These pins facilitate accurate alignment of the LEDs, preventing misalignment during assembly and ensuring uniform illumination across the keyboard.
Final Design Review Process
Upon completing the necessary design modifications, we provided our client with detailed 3D renderings of the updated silicone rubber keyboard. The client thoroughly reviewed the designs and granted approval to move forward with production. This collaborative effort exemplifies our commitment to working closely with clients to realize their visions while ensuring the highest quality standards.
