Metal dome array and sheet (dome array) is a PET sheet containing a 메탈 돔, which is used as a switch on circuit boards such as PCB or FPC and plays an important role between the user and the instrument. The function of the tactile switch. Can be easily peeled off the release paper and stuck on the circuit board as a switch for electronic equipment. Therefore, from the perspective of metal shrapnel encapsulation, it also requires a ” Peel & Place metal dome”. You can place one or more metal domes in each array depending on the design purpose, mostly in the same number and position as the PAD of the circuit board to which it will be posted.
Dome Arrays (Metal Dome Arrays) are the most cost-effective simple switching solution with a superior tactile interface between your device and the user. It has a nice click feel compared to the membrane polyester switches previously used. Due to the use of metal domes, it also lasts longer compared to polymer dome sheets.
The metal dome contacts on the array (sheet) sit above the contact points on the PCB. When the metal dome is pressed, the center of the dome contacts the PCB and allows current to flow. This is how metal dome arrays work. Please click on our blog to learn How to Place a Metal Dome Array on a Circuit Board.
Metal dome arrays (metal dome) of various sizes can be manufactured and meet customer requirements. At present, the metal dome arrays we produce have the following basic types.
Used for: remote controls, MP3, MP4, GPS systems, electronic dictionaries, digital photo frames, etc.; mobile phones, PHS, cordless phones, handsets, walkie-talkies, etc. Digital electronic products with buttons…
Metal Dome Array Features:
Chemical resistance, weather resistance, and damage resistance;
Ø 3 to Ø 6 mm, 100 g to 250 g driving force;
Typical life span is greater than 1M cycles;
You can choose the version with or without pits.
Metal Dome Array Advantages:
1. Shorten Production Time and Easy Assembly
The dome array is easy to assemble, and all domes can be placed on the PCB at the same time to shorten production time. The combination of automated processes will bring extremely low unit costs and improve production efficiency.
2. Ensure Quality
Dome arrays can reduce quality issues associated with dome placement because these arrays or dome sheets prevent misalignment or misalignment of dome pads, upper domes, and double dome misalignment during assembly.
Single Layer Metal Dome Array:
Single-layer dome arrays are used in dome arrays. Metal dome contacts are attached underneath Maylar, a layer of adhesive PET film. On the lamella, each dome contact has an air hole for a nice click feel.
Double Metal Dome Array:
Dual-layer dome arrays are somewhat similar to single-layer dome arrays and are implemented with metal dome contacts attached underneath the Maylar. But the pads in the double-dome array are attached underneath the metal dome contacts. The air paths function like air holes in the single layer, contributing to a nice clicky feel when pressing the dome contacts. In addition to this effect, the air channels help reduce the chance of damage to the PET film by metal dome contact burrs and prevent dust from entering the PET film.
EMI Printed Metal Dome Array:
EMI Printed Dome Array On top of a Mayler with metal dome contacts, silver paste or silver carbon paste is printed for ESD (Electrostatic Discharge Control). This helps reduce static electricity that can be harmful to other parts of your phone. Static electricity collects on the printed silver paste or silver carbon paste and is neutralized.
-EMI Single Layer Metal Dome Array
The EMI Single Layer Dome Array is a specialized metal dome array designed to provide both excellent tactile performance and effective electromagnetic interference (EMI) protection. In this configuration, an EMI shielding layer—typically silver paste or silver carbon paste—is printed directly on top of the single-layer dome array. This coating helps prevent electrostatic discharge (ESD) and electromagnetic interference that may affect the operation of nearby electronic components.Because the EMI layer is printed on the top surface of the PET sheet, the structure remains lightweight and flexible while offering stable conductivity. The EMI single layer dome array is widely used in mobile devices, communication equipment, and precision control panels, where compact structure and high reliability are critical. It combines smooth tactile feedback, long lifespan, and enhanced protection against static electricity—all in one cost-effective solution.
-EMI Double Layer Metal Dome Array
The EMI Double Layer Dome Array features an additional insulating and air channel layer, giving it better durability and tactile performance compared to the single-layer version. Like the single-layer type, the EMI layer is printed on top of the dome array, but the double-layer structure improves mechanical strength and prevents damage to the PET film caused by the dome edges.This design enhances airflow and provides a crisp click feel when the metal dome is pressed. The EMI coating effectively blocks unwanted electromagnetic signals and reduces ESD risks, ensuring the device functions smoothly even in harsh electromagnetic environments. The EMI double layer metal dome array is ideal for high-end electronics, industrial keypads, and smart control devices, where both tactile response and signal stability are crucial.
Rubber Metal Dome Array:
The Rubber Dome Array integrates a special layer of rubber glue applied on top of the Maylar or EMI film, creating a strong and flexible bond with the keyboard or PCB surface. This adhesive layer provides excellent sealing and protection, ensuring the dome array stays securely in place even under continuous use.
Due to its elastic and resilient rubber properties, this type of metal dome array offers superior shock absorption and environmental resistance, making it suitable for outdoor electronics, industrial control panels, and waterproof keypads. It also simplifies the assembly process by providing a ready-to-mount structure that adheres firmly to the substrate.
LGF Metal Dome Array:
The LGF Dome Array (Light Guide Film Dome Array) combines the tactile advantages of the standard metal dome array with light-guiding functionality. By adding a Light Guide Film (LGF) to an existing double-layer or EMI dome array, the LGF dome array achieves excellent light distribution across the keypad surface, ensuring that each button is uniformly illuminated.
This configuration is especially popular in backlit applications, such as automotive control panels, remote controls, and handheld electronic devices. The LGF layer allows the device to maintain a slim profile while providing both tactile feedback and visual enhancement. Overall, the LGF metal dome array is an advanced solution that improves user experience, aesthetic appeal, and functional efficiency in modern electronic designs.
Custom Dome Arrays:
Shanyo engineers independently developed the automatic shrapnel attachment and assembly machine equipment, which is more convenient, less troublesome, more accurate, and faster than manual labor. The metal shrapnel is independently developed and stamped and has multiple patents. Order now.
