Analysis of the use of metal domes in silicone rubber keyboards The metal dome used on the silicone membrane keyboard is mainly located on the conductive part of the PCB (mostly above the gold fingers on the circuit board). While the metal dome is mainly made of stainless steel, the metal dome plays an important role in the tactile switch and also has conductive properties. When the silicone rubber keypad is pressed, the center point of the metal dome is concave and contacts the circuit on the PCB to form a loop. The metal dome is reflowed to make the silicone rubber keyboard work. The metal dome array consists of individual metal domes on a pressure sensitive bonded PET sheet, each individual metal dome occupying a designated position on the dome display. This kind of position is after the supplier provides the drawing and confirms with the engineer, advanced proofing, and then starts mass production to ensure the availability of the product and reduce the error rate of the product. At the same time, a detachable anti-adhesive backing is arranged on the metal dome display, which allows customers to use it more efficiently. Silicone rubber keyboard in use, the dome display provides a new tactile experience, due to the different design, the metal dome provides users with a unique and satisfying keystroke response when pressed, improving the user’s comfort during use sex. The metal dome is an inseparable component in work and life, it connects the command transmission between us and the machine. There is a metal dome added to the silicone rubber keyboard, which makes the transmission command fast, accurate and efficient. From modern consumer electronics to industrial mechanical interfaces, the sophistication and reliability of metal domes has evolved little by little. https://www.metal-domes.com/blog/2023/09/01/analysis-of-the-use-of-metal-domes-in-silicone-rubber-keyboards/
