Overview:
Custom Gold & Silver Plated PCB Battery Copper Spring Contacts are precision-engineered conductive components designed to deliver superior electrical performance, corrosion resistance, and mechanical resilience in electronic assemblies. Manufactured from high-conductivity copper, phosphor bronze, or beryllium copper, these contacts are produced using advanced progressive stamping and precision forming technologies. Each spring contact is optimized for consistent contact pressure, low resistance, and long-term cycle life—making it ideal for PCB-mounted battery terminals, mobile devices, medical electronics, and automotive control systems.
With decades of OEM manufacturing experience, we provide customized contact solutions to meet your unique electrical, mechanical, and environmental requirements, from prototype design to large-scale mass production.

- Silver Plating: Offers high conductivity and cost-effective performance for power transmission and grounding contacts.
- Nickel Underplating: Acts as a diffusion barrier to enhance durability and adhesion of top coatings.
- Tin Plating: Delivers reliable solderability and anti-oxidation protection for assembly efficiency.
- Selective Plating: Enables cost control by applying premium coatings only on contact surfaces for functional performance.
Quality Assurance:
Our quality assurance system ensures every Custom Gold & Silver Plated PCB Battery Copper Spring Contact meets strict international standards for conductivity, elasticity, and durability. Certified under ISO 9001:2015 and IATF 16949:2016, we perform comprehensive inspections including dimensional verification via CMM, micro-ohmmeter tests for contact resistance, spring force calibration, and plating thickness analysis using X-ray fluorescence (XRF). Corrosion resistance and fatigue life are validated through salt spray and cyclic endurance testing, ensuring reliable performance even under repeated compression and vibration.
Factory Show:
Our precision metal stamping facility integrates high-speed progressive stamping machines (15–250 tons) with automated plating, heat treatment, and forming lines for efficient, scalable production. Tooling and dies are developed in-house using CNC machining, wire EDM, and mirror polishing to ensure micron-level accuracy. Automated plating lines support gold, silver, and selective plating with uniform thickness control. Supported by SPC monitoring, full material traceability, and rigorous quality documentation, we guarantee stable, repeatable output for every OEM project.With end-to-end manufacturing—from tool design and prototyping to automated assembly—we deliver high-performance electrical contacts trusted across consumer electronics, automotive, and industrial applications.
