Products Description
Our Electric Contact Gold Plated and multi-material contacts are designed for environments where failure is not an option:
Material Synergy: 99.99% pure gold (Au) plating on bases like copper (for cost-efficiency), bimetal (copper-tungsten/copper-silver), or tri-metal composites, creating a low-resistance interface that resists oxidation and wear.
Thickness Control: 1-3μm gold layers (customizable to 5μm) applied via advanced electroplating, ensuring uniform coverage on complex shapes (rounded rivets, stepped bimetal contacts) with Ra ≤0.1μm mirror finish.
Application Focus: Optimized for gold-plated bimetal contacts in military relays and gold-plating copper rivets in precision switches, balancing the conductivity of gold with the mechanical strength of base materials.
Key Advantages
1. Unmatched Performance in Extreme Conditions
0.5% Signal Loss at 60GHz: Gold's atomic smoothness minimizes high-frequency attenuation, critical for radar systems and satellite communications-5x better than silver-plated alternatives.
2,000+ Hours Salt Spray Resistance: 3μm gold plating passes MIL-STD-810G testing without pitting, making it ideal for marine, airborne, and underground military equipment.
-65°C to +200°C Stability: Maintains ≤2mΩ contact resistance across extreme temperatures, ensuring reliable operation in missile guidance systems and deep-space probes.
2. Precision Plating for Complex Structures
| Technology | Advantage | Typical Application |
| Pulse Electroplating | 0.05μm/min deposition rate, ±5% thickness control | Micro-miniature contacts (φ0.8mm) |
| Nickel Underlayer | 10μm electroless nickel boosts bond strength to 80MPa | High-vibration aerospace relays |
| Cleanroom Processing | ISO 8 cleanroom prevents particle contamination | Quantum computing connectors |
3. Factory-direct expertise for Critical Projects
Cost Efficiency (Relative to Quality): While gold plating costs 3-5x base materials, our in-house plating reduces subcontractor markups by 20%, offering 15% lower prices for MIL-S-45204-compliant contacts.
Certifications: ISO 9001, RoHS.
Rapid Prototyping: 5-day turnaround for custom samples (including bimetal and copper rivet variants), with dedicated support for defense/aerospace customers requiring FAIR reports and material traceability.
Applications
Military & Defense
Gold Plated Bimetal Contacts: Used in missile launch relays to withstand 100g shock and 200℃ engine bay temperatures, ensuring instantaneous signal transmission during launch.
Gold Au Coated Contacts: Submarine communication switches with 2μm gold plating resist seawater corrosion for 10+ years of submerged operation.
Aerospace & Aviation
Gold Plating Copper Rivets: Lightweight (0.5g/pc) gold-plated copper rivets in aircraft avionics, minimizing signal loss in high-frequency data buses (10Gbps+).
High-Altitude Relays: 1μm gold-coated composite contacts maintain conductivity in vacuum conditions (-100kPa), critical for satellite power distribution systems.
High-End Industrial & Precision Instruments
Semiconductor Equipment: Gold-plated bimetal contacts in wafer handlers resist chemical vapors (HF, O2 plasma), ensuring 99.999% uptime in cleanroom environments.
Medical Implants: 0.5μm gold-plated micro-rivets (φ0.8mm) for pacemaker connectors, biocompatible and stable over 15+ years of continuous use.
Factory Strengths: Vertical Integration for Mission-Critical Quality
1. Specialized Plating Capabilities
Bimetal Expertise: Unique ability to plate complex bimetal structures (e.g., copper-tungsten with 45° angled contact surfaces) without edge thinning, a common challenge in subcontracting.
Rivet Precision: Automated systems ensure uniform gold plating on copper rivet heads (even concave/convex surfaces), with thickness variation <3% across the entire contact area.
2. Military-Grade Quality Assurance
5-Step Inspection for Defense Orders:
Purity Check: 100% XRF to confirm 99.99% gold content.
Thickness Mapping: Automated XRF scanning for every contact.
Adhesion Test: Scratch test with zero plating detachment.
Environmental Testing: Thermal cycling (-65°C to +200°C, 100 cycles) and vibration (20g, 10-2000Hz) for military compliance.
Visual Inspection: 100% optical screening with 5μm resolution to reject any surface defect.
3. Customization & Support
Material Consultation: Engineers assist in selecting the optimal base material (copper for cost, bimetal for strength) and gold thickness (1μm for signals, 3μm for high current).
Documentation Package: For defense/aerospace customers, provide DFARS-compliant material certificates, process flow diagrams, and failure mode analysis (FMEA) reports.
