Gold-Plated Copper Alloy Wire for Flexible PCB and Sensor Applications is designed to meet the critical demands of compact electronic systems, where flexibility, high conductivity, and corrosion resistance are essential. Featuring a high-purity copper alloy core with precise gold plating, this wire offers excellent mechanical endurance, stable electrical performance, and easy integration into flexible printed circuits and precision sensor assemblies.
Its ultra-smooth surface and fine-diameter control ensure superior bonding, solderability, and long-term reliability in dynamic, space-constrained environments.
Gold-plated surface minimizes oxidation and maintains stable electrical contact
Fine-diameter flexibility supports intricate FPC routing and micro-assembly
High mechanical strength ensures durability under repeated flexing and bending
Smooth, bright finish enhances wire bonding and soldering consistency
Customizable specifications to match specific PCB layouts and sensor designs
Flexible printed circuit (FPC) reinforcement and dynamic signal paths
Micro-sensor wiring for medical, aerospace, and IoT devices
Fine-pitch bonding in wearable electronics and portable devices
Dynamic interconnections in flexible displays and smart modules
High-precision signal transmission in microelectronic sensing platforms
