Tin Plated Copper Bus Bar
Products Description
Tin Plated Copper Bus Bar is an integrated high-performance conductive connection component based on a multi-layer ultra-thin copper foil stacked structure, formed through a diffusion welding process. This product uses multiple layers of 0.05–0.2mm ultra-thin electrolytic copper foil, stacked and bonded at the molecular level through high-temperature diffusion welding, giving the overall conductor both excellent conductivity and a flexible structure. The busbar surface can be tin-plated or covered with an insulating layer according to application requirements to improve oxidation resistance and environmental adaptability.
Material Properties and Advantages
High-purity T2 copper material
Copper purity for Flexible BusBar Copper reaches over 99.9% (higher than the national standard of 99.85%), ensuring excellent conductivity and long-term stability.
01
Ultra-thin copper foil laminated structure
0.05–0.2mm electrolytic copper foil is laminated to form a flexible conductive structure for Multilayer Bus Bar, avoiding the rigid limitations of traditional thick copper busbars.
02
Low resistivity performance
Flexible copper laminated busbar resistivity ≤0.021μΩ·m, effectively reducing energy loss and improving system efficiency.
03
Grain refinement process
Through grain refinement control, the average particle size is <50μm, improving the material's mechanical properties and conductivity uniformity.
Copper Flexible Busbar.

Technical Features
Effective Current Distribution
Traditional solid busbars are prone to current density concentration at bends, but the Copper Flexible Busbar design effectively eliminates this defect, ensuring uniform current distribution throughout the busbar.
High Conductivity
Extremely low resistivity, ≤0.021μΩ·m, ensuring low voltage drop operation under high load conditions for Flexible copper laminated busbar.
Customizable Surface
In addition to the basic tin plating, the surface can be covered with a high-grade insulating layer or a special protective plating (such as silver plating) to meet the needs of different environments for Multilayer Bus Bar.
Strong and Tough Bonding
Utilizing a diffusion welding process, the strength and integrity of each copper foil layer are ensured, preventing delamination and extending service life.
