Connectors in UAV & Drone Systems
Connectors are essential components in UAV and drone systems, ensuring reliable power and signal transmission between flight controllers, batteries, sensors, and communication modules. Designed for demanding environments, UAV connectors must offer excellent conductivity, vibration resistance, and corrosion protection. Qianwei Precision provides high-quality connector components that help enhance system reliability, performance, and service life in aerospace and drone applications.
Customer Requirements
Qianwei Precision Solution
A UAV manufacturer required a custom semi-gold plated terminal capable of delivering reliable electrical connections in demanding operating environments. The terminal needed to meet strict environmental and quality standards while maintaining excellent corrosion resistance and long-term performance.
Key requirements included:
- RoHS-compliant materials and manufacturing processes
- Excellent corrosion resistance
- No functional-impacting cracks or burrs
- No deformation, oxidation, contamination, or surface defects
- Stable electrical connection performance
- Capability to pass 48-hour Neutral Salt Spray Testing
- Custom dimensions and plating specifications for UAV applications
Because UAV systems rely on lightweight yet highly reliable electrical interconnections, even minor connector failures could affect operational stability and safety.
To meet the customer's requirements, Qianwei Precision developed a custom KT950431108-150C semi-gold plated terminal manufactured from high-conductivity copper.
Our engineering team optimized both the material selection and plating process to ensure superior corrosion resistance and reliable conductivity.
Solution highlights:
- High-conductivity copper base material
- Material thickness: 1.5 mm
- Nickel underplating: 60–150 μin
- Full-area gold plating: minimum 0.5 μin
- Precision stamping and forming technology
- Strict burr and crack control
- Customized dimensions according to customer specifications
- RoHS-compliant production process
The optimized plating structure significantly improved corrosion resistance while maintaining stable electrical performance in UAV operating environments.
