A Tin Coated Copper Busbar is a high-conductivity copper conductor with a protective tin layer, designed to provide excellent electrical performance, corrosion resistance, and long-term reliability. Also known as a Tinned Copper Busbar or Tin Plated Copper Bus Bar, it is widely used in battery packs, switchgear, EV systems, industrial power distribution, and grounding applications.
These busbars combine the superior conductivity of copper with a tin coating to prevent oxidation, enhance solderability, and maintain low contact resistance in harsh environments.
Creating a reliable Tin Plated Copper Bus Bar involves several precise steps:
Material Selection: High-purity copper (T2, C11000, or oxygen-free copper) ensures excellent conductivity.
Cutting & Shaping: CNC machining, stamping, or rolling creates precise dimensions for Custom Tin Coated Copper Busbar requirements.
Tin Coating: Electroplating or hot-dip tinning adds a protective layer to resist corrosion and improve solderability.
Customization: Holes, bends, slots, and insulation can be added to meet specific layouts, including Tin Plated Copper Ground Busbar applications.
Inspection: Each batch undergoes conductivity, mechanical, and plating adhesion tests to ensure long-term reliability.
