What Is Dome Sheets & UV？
Dome Sheets & UV represent an advanced evolution of the standard Metal Dome Sheet, incorporating a precision application of Ultraviolet (UV)-curable adhesive for functional enhancement. This process involves depositing specially formulated UV glue onto specific areas of a dome array—such as around the dome periphery or contact points—which is then instantly cured by UV light to form robust sealing rings, protective barriers, or tactile bumps. This is more than a manufacturing step; it’s a functional upgrade that transforms a standard metal dome array into a highly integrated module with superior environmental sealing and custom tactile haptics, specifically engineered for demanding applications.

Why Choose Shanyo's Dome Arrays?
The integration of UV curing technology delivers multidimensional performance enhancements for Dome Sheets:
Superior Environmental Sealing & Protection
The cured UV adhesive creates seamless gaskets that effectively block moisture, dust, corrosive gases, and liquids from penetrating the Dome Sheets UV assembly. This is critical for achieving high Ingress Protection (IP) ratings like IP67/IP68, making Dome Sheets &UV ideal for harsh environments.
Enhanced Structural Stability & Durability
The cured polymer layer securely bonds the metal domes, circuits, and overlay materials together. This prevents delamination or shifting caused by repeated actuation, vibration, or thermal cycling, significantly boosting the mechanical lifespan and reliability of the entire metal dome array.
Customized Tactile & Ergonomic Design
By forming precise UV-cured tactile bumps over specific keys, the pressing feel—such as actuation force or travel-end hardness—can be fine-tuned without altering the metal dome itself. These bumps also provide physical guidance for blind operation, greatly expanding the tactile design possibilities of a Metal Dome Sheet.
Efficient & Precise Manufacturing Process
UV curing happens within seconds, enabling high production efficiency. The application location, shape, and volume of the adhesive are precisely controlled via programming, ensuring exceptional batch-to-batch consistency for Dome Sheets &UV products.
Excellent Chemical & Thermal Stability
Once cured, the UV adhesive layer exhibits strong resistance to chemicals, high temperature/humidity, and UV aging, ensuring the added functionalities remain reliable throughout the product's operational life.

자주 묻는 질문
Q: Does adding the UV process significantly increase the overall thickness and cost of the Dome Sheet?
A: The thickness increase is minimal. UV adhesive layers or bumps can be precisely controlled within a range of 0.1mm to 0.3mm. While cost increases depend on the adhesive type, volume, and complexity, it represents a high-return investment. The added value comes from dramatically improved reliability, achieved waterproofing ratings, and enhanced product differentiation, which can reduce long-term failure risks and warranty costs.
Q: Does this process affect the electrical conductivity or lifespan of the metal dome sheets?
A: Not at all. Professional Dome Sheets UV manufacturing precisely avoids the critical electrical contact areas of the metal domes. The UV adhesive is used for sealing, reinforcement, or creating external tactile structures, leaving the dome’s electrical performance (like contact resistance) and mechanical lifespan (typically still 1 million+ cycles) completely unaffected. In fact, it protects these properties through added stabilization and sealing.
Q: What about the long-term reliability of the UV adhesive? Will it yellow or peel over time?
A: We use high-performance, electronics-grade UV-curable adhesives with excellent yellowing resistance (UV stability), and resistance to thermal humidity and chemicals. When processed with correct parameters, the cured adhesive forms an extremely strong bond with substrates like PET and metal. It is designed to pass stringent environmental reliability tests (e.g., damp heat, thermal shock, salt spray), ensuring it remains stable, non-degrading, and does not peel for the product’s entire service life.
Q: Can we customize the color, shape, and location of the UV adhesive?
A: Absolutely. Customization is a core strength of the Dome Sheets &UV solution. We can tailor the UV application precisely based on your panel design (e.g., matching keycap color), tactile needs (e.g., different bump shapes for different functions), and sealing requirements. Please provide your specific needs and drawings, and our engineering team will develop a tailored solution.
