What Is a Dome Sheet Array?
A dome sheet array — also known as a metal dome array, dome array sheet, or dome sheet — is a pre-assembled component that mounts multiple metal domes onto a single adhesive-backed PET (polyester) sheet. Each dome is precisely positioned over a corresponding contact pad on a PCB or FPC, so that when the sheet is applied, every dome lands exactly where it needs to be. Instead of placing domes one by one by hand, a dome sheet array lets you peel and stick the entire keypad layout in one step — dramatically speeding up assembly and eliminating positioning errors.
📌 What a dome sheet array does:
A dome sheet array sits between a graphic overlay and a circuit board, turning a scattered set of individual metal domes into a single, easy-to-handle keypad module. It ensures consistent dome placement, protects the domes from dust and moisture, and gives every key a uniform tactile click. It is the core actuation layer in remote controls, medical keypads, automotive interfaces, industrial control panels and consumer electronics.
📌 Custom layouts and constructions:
We supply dome sheet arrays in single-layer, double-layer and spacer-on-top constructions, with custom dome positions, venting cuts and adhesive zones tailored to your PCB or FPC design. Round domes, four-leg domes and triangle domes can be mixed on the same sheet. Share your layout drawing and we will tool, assemble and sample to it.
📌 Integrated FPC + dome array solutions:
For applications that need both the circuit and the dome array, we offer FPC + dome sheet array combined modules — the flexible printed circuit and the dome array are produced and aligned in-house, reducing your assembly steps and supply chain risk. This is especially popular in wearable devices, sports watches and medical handhelds where space is tight.
📌 Quality and lifecycle:
Every dome sheet array goes through in-house CCD visual inspection before shipping — dome position, adhesive integrity and electrical continuity are checked 100%. Standard dome life reaches 1,000,000 cycles, and gold-plated domes are available for high-reliability or low-contact-resistance requirements. We support both small-batch prototyping and mass production with consistent quality.

Types of Dome Sheet Arrays
Shanyo engineers six standard dome array constructions, each optimized for a specific tactile profile, environmental condition and assembly workflow. Custom layouts and hybrid structures are available on request.
Single-Layer Dome Array
The foundational construction: precision-stamped stainless-steel domes laminated onto a single PET carrier sheet with pressure-sensitive adhesive. Actuation force spans 10–200 gf with 0.05–0.5 mm travel, and contact resistance stays below 100 mΩ. Rated for 500,000+ cycles across a -40°C to +85°C operating window.
Best for: remote controls, calculators, low-cost consumer keypads
LGF-Integrated Dome Array
Combines a light-guide film (LGF) layer with the dome sheet in a single lamination pass, enabling uniform LED backlighting across every key without light bleed between positions. The light-blocking overlay ensures crisp, even illumination. Force and travel match the single-layer baseline, with the same 500K+ cycle rating.
Best for: backlit remote controls, automotive infotainment panels, smart home keypads
UV-Bump Dome Array
Features UV-cured protrusion dots printed directly onto the dome sheet surface, creating raised tactile zones that guide the user's finger to the exact key center — ideal for blind operation. The bumps also improve actuation precision and reduce mis-presses. Built on PEN substrate for enhanced durability and 1,000,000+ cycle life.
Best for: industrial handhelds, POS terminals, walkie-talkie
Bend-Insulated Dome Array
Incorporates a pre-bent insulating spacer sheet that creates the precise actuation gap between dome and circuit while preventing electrical shorting. The bend profile is custom-tooled to match the enclosure geometry. Uses PEN substrate with 301 stainless-steel domes, delivering 1M+ cycles and consistent force across the full -40°C to +85°C range.
Best for: automotive steering-wheel switches, appliance control panels, industrial HMIs
Bend + 3M-Adhesive Dome Array
The bend-insulated construction laminated with 3M double-sided adhesive for secure, long-term bonding to PCB or enclosure surfaces — eliminating the need for additional fasteners. The high-tack adhesive maintains bond integrity through thermal cycling and vibration. Premium option upgrades to PI substrate with beryllium-copper domes for 5,000,000 cycles and -55°C to +125°C endurance.
Best for: automotive smart-cockpit panels, outdoor equipment, medical device interfaces
IP67/IP68 Sealed Dome Array
Engineered with a labyrinth-edge seal and nano-hydrophobic coating to achieve IP67 (splash-proof) or IP68 (3-meter submersion) ingress protection. The flagship PI-substrate version supports 5–500 gf customizable force, 0.02–1.0 mm travel, and below-50 mΩ contact resistance with 5M+ cycle life. Validated for 1000 hours at 85°C/85%RH damp heat and 500 hours UVB irradiation.
Best for: outdoor/military keypads, marine navigation, food-equipment controls, wet-environment HMIs

FAQ
FAQ
Q: Can you customize dome sheet arrays with mixed‑force keys on one single sheet?
A: Yes. We can integrate multiple metal dome types with varied actuation force, click ratio and stroke onto one laminated array sheet. Different tactile feedback can be assigned for power keys, function keys and navigation keys according to your design drawing. Both standard and irregular keypad layouts are supported.
Q: Do you provide dome sheet array samples? How long is the sample lead‑time?
A: We offer free standard‑layout samples for evaluation. For custom‑layout dome sheet arrays, tooling is required. Normal sample lead‑time runs 7‑12 working days after drawing confirmation. We also provide force‑test prototype kits for tactile validation before formal tooling.
Q: What certifications do you support for dome sheet arrays used in automotive & medical devices?
A: Our dome sheet arrays are manufactured under IATF 16949 for automotive projects and ISO 13485 for medical equipment. Products comply with RoHS, REACH, ISO9001, ISO14001 and ISO45001. Material certificates and test reports can be provided upon request.
Q: What substrate options are available for dome sheet arrays? What are their differences?
A: We supply PET, PEN and PI substrates. PET is cost‑effective for general‑purpose consumer electronics. PEN delivers stable performance under cyclic temperature changes. PI suits high‑temperature, high‑reliability scenarios for automotive, industrial and medical applications.
