What is the production for tin plated car battery busbar?

The car of busbar adopts 99.9% high purity T2 copper substrate (in line with GB/T 5231 standard), copper foil laminated molding through molecular diffusion welding technology, combined with self-developed acidic cleaning solution and plating aid system:

• Tin plating process: 0.03-0.3mm precision copper foil plating, tin layer thickness 3-12μm adjustable (standard value 6μm)
• Surface treatment: Remove oxides by sodium o-nitrophenol compound cleaner, and cooperate with tin chloride-based plating auxiliaries to realize atomic level bonding.
• Structural design: support flexible stacked structure (bending radius ≥15mm), to meet the dynamic stress requirements of EV battery packs.

How is the performance for tin plated car battery busbar?

What are the advantages for tin plated car battery busbar?

1. Highly efficient conductive system
   Copper substrate conductivity of 100% IACS, tin plating only 6% lower conductivity (compared to 43% lower nickel plating), especially suitable for:
   • Battery Management System (BMS) high voltage circuits
   • Motor controller main power paths
   • DC link for fast charging piles (supporting 500A/5 seconds pulse)
2. Long-lasting protection mechanisms
   Tin plating forms a dense oxide film (thickness 0.5-2nm), which improves oxidation resistance by 8 times compared to bare copper:
   • Humidity cycling test: resistance change rate <2% for 2000h under 85℃/85%RH conditions
   • Chemical resistance: Passed SAE J2334 corrosive solution test.
3. Customized engineering services
   Equipped with fully automatic laser cutting system and robotic welding cell to support:
   • Shaped structure: Maximum size 3000×150×10mm (length×width×thickness)
   • Connection program: optional laser welding / crimp terminals / PCB direct connection
   • Insulation configuration: PVC impregnated (3500VDC) or silicone composite sleeve

What is  the application for tin plated car battery busbar?

• Power battery packs: Inter-module jumper connection (supporting ≤3mΩ contact resistance)
• Distribution centers: replacing traditional wiring harnesses, 40% increase in space utilization
• Charging infrastructure: liquid-cooled system conductor (with 6063 aluminum alloy heat dissipation housing)

How is Manufacturing Capability and Quality Assurance?

Relying on 100,000-class clean workshop and full-process inspection system (including X-ray coating analyzer and infrared thermal imager):

• Production precision: ±0.05mm dimensional tolerance (ISO 2768-mK grade)
• Deliverability: 5-15 working days for fast samples, support PPAP level 3 document delivery
• Environmental standards: RoHS/REACH compliant, acid mist emission <5mg/m³

The solution builds a complete technical value system by integrating the material characteristics, process innovation and engineering verification data of tinned copper busbar, which is especially suitable for the upgrade needs of the three power systems of new energy vehicles. For customized solutions or validation samples, it is recommended to provide specific application parameters for DFMEA analysis.
