How are metal domes manufactured?
The manufacturing process of metal domes is precise and highly controlled. Each step plays a critical role in ensuring the final product delivers consistent tactile performance and long service life. The process begins with high-quality stainless steel sheets. These sheets are selected based on thickness, hardness, and surface finish. The material must meet strict standards to ensure durability and elasticity.
The main production steps include:
- Stamping: The metal sheet is stamped into the desired dome shape using high-precision molds
- Forming: The dome structure is shaped to achieve the correct tactile force and snap ratio
- Heat treatment: This step enhances elasticity and ensures stable performance over repeated use
- Surface cleaning: Removes contaminants to improve conductivity and reliability
- Plating (if required): Gold or nickel plating may be applied for better corrosion resistance
- Inspection: Each batch undergoes strict quality checks for force, size, and consistency
After individual domes are produced, they may be assembled into arrays. This involves placing the domes onto adhesive carriers with precise alignment. Advanced factories maintain placement accuracy within ±0.05mm, which is critical for automated assembly.
The final step may include packaging in Tape & Reel format. This allows domes to be picked and placed by SMT machines, significantly increasing assembly speed and reducing labor costs.
What materials are used in standard metal dome manufacturing?
Material selection is a key factor in determining the performance and lifespan of metal domes. The most commonly used material is stainless steel, known for its excellent balance of strength, elasticity, and corrosion resistance. Different grades of stainless steel are used depending on the application. These grades vary in hardness and flexibility, which directly affect tactile feedback and durability.
Common materials include:
- SUS301 stainless steel: Offers high elasticity and is widely used for tactile domes
- SUS304 stainless steel: Provides better corrosion resistance and is suitable for harsh environments
- Nickel-plated steel: Enhances conductivity and improves surface durability
- Gold-plated domes: Used in high-end applications requiring superior conductivity and reliability
Each material has its own advantages. For example, SUS301 is often preferred for applications requiring a sharp tactile response, while SUS304 is better suited for environments with higher humidity or exposure to chemicals.
Factories like EBest Circuit (Best Technology) carefully select materials based on customer requirements. This ensures that each dome meets specific performance criteria, whether it is for a consumer device or an industrial control panel.
