    Copper Foil Flexible Busbar For High Current Application

    Copper Foil Flexible Busbar (also named Laminated Copper Connector ) is a high-performance flexible electrical conductor, manufactured by stacking multiple layers of high-purity copper foil and integrally welding both ends via molecular diffusion bonding. It is designed for high-current, high-reliability, vibration-prone, and space-constrained power connections.
    Conductor Material: T2/TU2 High-Purity Electrolytic Copper (Cu ≥99.95%）
    Copper Foil Thickness: 0.05mm / 0.1mm (standard) / 0.2mm / 0.3mm / 0.5mm
    Surface Treatment: Bare Copper / Tin-Plated / Nickel-Plated / Silver-Plated
    Customization: Width, thickness, total length, welding length, hole pattern, bending shape (custom per drawing)
