Dome Arrays

1. Introduction to Dome Arrays

SHANYO is a professional supplier of metal dome arrays, which has focused on offering integrated tactile switch solutions of high performance and reliability. Metal dome arrays belong to those products that integrate several precision metal domes onto flexible or rigid carriers in any arrangement, thereby building standardized switch array modules that considerably facilitate the PCB assembly process by speeding up production and increasing consistency. Such consumer goods find vast application in industrial equipment, medical apparatus, automotive electronics, and auxiliary fields under harsh environmental conditions for touch control requirements.

2. Features of Dome Arrays

Highly Integrated Design

Multiple metal domes are pre-assembled into an array structure, supporting high-density layouts and reducing the number of individual component placement steps.

Accurate Tactile Sensation

It provides clear touch with consistent actuation force, e.g., 3N-5N, for better user experience.

Strength and Long Life

Made of stainless steel, e.g., SUS 301/304, they have a life of more than one million cycles plus corrosion resistance and high-temperature resistance.

Customizable Flexibility

Customizable within the following spring size and arrangement. Substrate type (Polyester film, FPC, PCB, etc.).

Compatible for Automated

Production via SMT placement process, thereby improving the assembly efficiency as well as reducing labor cost.

3. Customer Benefits of Dome Arrays

Simplified Supply Chain Management

The integrated array structure reduces component count, simplifying procurement and inventory management complexity.

Improved Product Reliability

Avoids individual spring assembly errors, ensuring stable overall switch performance and reducing after-sales failure rates.

Cost Optimization

Standardized modular design reduces assembly time, and large-scale production further reduces unit cost.

Accelerated Product Development

Provides rapid prototyping support and customized solutions, shortening customer R&D cycles.

Technical Collaboration Support

Our engineering team provides selection guidance, adaptation testing, and failure analysis services.

4. Application Scenarios of Dome Arrays

Industrial Control Equipment

POS terminals, printer control panels, and industrial instrument keypads (e.g., waterproof and dustproof arrays for outdoor use).

Consumer Electronics

Game controllers, VR device buttons (such as military-grade VR controllers), and smart home control panels.

Medical Devices

Medical instrument buttons and handheld testing equipment user interfaces (must meet disinfection tolerance requirements).

Automotive Electronics

Vehicle center consoles, instrument panel buttons, and steering wheel control modules.

Home Appliances and IoT

Microwave oven panels, air conditioning controllers, and smart wearable device interaction modules.

5. FAQ

Q1: Can the shape and connection method of Dome Arrays be customized based on our PCB layout?

A1: Yes, SHANYO offers full customization services. We can provide a fully customized metal dome array solution based on your PCB design requirements, including connection solutions such as FPC cables or solder pad positioning.

Q2: What substrate types are available for Dome Arrays? Are there waterproof and dustproof options?

A2: Polyester film (PET), flexible printed circuit boards (FPCs), and rigid PCB substrates are the main substrate offerings that we supply. In special applications, Dome Arrays can also be installed with extra waterproof adhesive layers or coatings-as an example, a silicone seal.

Q3: What is the minimum order quantity (MOQ) for Dome Arrays? How can I obtain samples?

A3: MOQ of Dome Arrays is based on the level of complexity in design, between 1,000 and 5,000 units. We have a< free dome array sample test> (you just pay for shipping) plus a full report on compatibility verification.

Q4: What is the actuation travel and force tolerance for metal dome arrays?

A4: Our standard tolerance for Dome Arrays is ±10%, and we also offer customization with ±5% for higher precision. The specific tolerance depends on the dome size and material properties. Our engineers will provide expert advice based on your Dome Array application needs.

Q5: Do you support Dome Arrays with high-temperature or special environmental requirements?

A5: Yes, SHANYO can provide special specifications for metal dome arrays, including high-temperature substrates (such as polyimide) and specialized plating treatments to enable Dome Arrays to withstand reflow processes or various extreme environmental conditions.
