Surface Treatment & Integration Options:
- Embedded Nickel Pill Precision
During compression molding, each nickel pellet is robotically placed into a preformed cavity, ensuring perfect alignment and uniform contact resistance across every button. - Custom Pad Printing
Apply high-conductivity silver or durable epoxy-based inks to create crisp, high-contrast legends and custom graphics without sacrificing conductivity. - High-Precision Laser Etching
Permanent, high-resolution laser engraving delivers sharp logos and icons, preserving the integrity of the silicone surface and nickel interface. - Selective Electroless Nickel Plating (Optional)
For applications requiring additional corrosion resistance, a uniform electroless nickel-phosphorus layer can be applied to surrounding contact pads, boosting wear tolerance and extending cycle life.
Quality Assurance:
Our comprehensive QA program, fully compliant with ISO 9001 and IATF 16949, guarantees automotive-grade reliability for consumer devices:
- Raw Material Verification
- Utilize FTIR spectroscopy to confirm silicone polymer purity and Rheometry to validate compound viscosity.
- In-Process Monitoring
- Deploy machine-vision systems to verify nickel pill placement accuracy (±0.02 mm) and maintain consistent silicone wall thickness.
- Dimensional & Hardness Testing
- Perform CMM inspections to validate critical dimensions within ±0.02 mm tolerances.
- Use Shore A durometers to ensure consistent hardness across each batch.
- Electrical Performance Verification
- Measure button contact resistance with precision milliohm meters, verifying each nickel pill achieves specified low-resistance thresholds.
- Conduct adhesion and peel tests between silicone and nickel components to ensure robust bond strength.
- Environmental & Durability Testing
- Subject samples to 60 °C humidity chamber cycles and mechanical endurance rigs (e.g., >50,000 actuation cycles) to confirm long-term tactile reliability.
- Final Inspection
- Every keypad undergoes 100% visual inspection in our inspection bay and functional testing (electrical continuity, tactile response) before packaging.
