The substantial gold coating provides multiple advantages for demanding industrial applications:
• Exceptional corrosion resistance preventing oxidation in harsh environments
• Stable electrical performance across temperature variations (-30°C to +70°C)
• Elimination of common defects including deformation, contamination, burrs, and material mixing
These precision-engineered domes are processed into complete solutions:
• PET Film Switch Modules - Custom arrays with 3M 468 or equivalent adhesives
• Specialized PET Solutions - Available with IP-rated 3M adhesive materials offering waterproof and high-temperature resistance (up to 85°C continuous operation)
• Dome Sticker Panels - Pre-aligned for manual or automated installation
• Reel Packaging - 5,000PCS units per reel for high-volume SMT production
Industrial applications include signal transmitters, control panels, medical equipment interfaces, and ruggedized handheld devices where reliability exceeds 1 million actuation cycles. The cross design provides optimal tactile feedback with actuation forces customizable from 150gf to 400gf.
BONSDA's manufacturing process ensures zero visual defects - no pressure marks, deformation, debris, or oxidation. Each dome undergoes 100% electrical testing and visual inspection before integration into PET carrier films.
Available for both prototype development and mass production, these gold-plated cross dome arrays combine the conductivity benefits of precious metal plating with the manufacturing efficiency of reel-to-reel processing.
