Flexible busbar is through brazing the copper foil parts together,which is 99.9% copper contented. It capitals the products excellect conductivity with less impurities. Laminated copper busbar have more current carrying surface area.
Copper foil: 0.05mm to 0.3mm thick. The contact surface can be tinned or silvered according to the user's requirements.The current is based on the customer's requirement of 1 square knitting belt & the effective loads current 4A calculation. Copper conductors with different sectional areas have different parameters. The large area can be multi-layer or set.The price depends on the current copper price and current size.

0.1/0.2/0.3/0.5/1.0mm,depend on bus bar structure, we will advise suitable thickness |
| Insulation Material | PVC Dipping Coating is good performance, Special shaped bus bar can be put on directly, it is not easy to break when it be bent with many times. |
| Insulation Performance | PE and PVC are good, PVC dipping is better than PE heat shrink tubes |
| Flame Retardant/Fire Resistance | UL94-V-0 or upon you request |
| Leakage Testing | PVC Dipping Sleeves: In condition of 3500VDC with 30s upon thickness 1.5mm, Leakage is 0.025 MA; In condition of 5000 VAC with 30s to 60s upon thickness 1.8mm to 2.0mm, Leakage is 0.065 MA; Or upon your working voltage, we advise to choose better solution. |
| Surface Plating | Nickel, tin or silver plated etc Plating Thickness:Normally 3um to 12um or upon customers' request |
| Salt Spray Testing | In a neutral environment, nickel can bear 240 hours. Silver is lower, tin is lowest |
| Bending Testing | Bend 10000 times in 15 radian angle without breakage or fracture. |
| Temperature Rise Testing | Depend on flexible busbar cross-sectional area, We can offer all temperature rising test report before delivery if you request |
| Operating Temperature | -45 to +150 ºC |
| Copper Foil Tensile Strength | ≥500N |
| Quote Time | Quotation sheet will be sent in 1-3 working days when receive your enqiury |

The manufacturing process of flexible copper busbars involves several key steps to ensure conductivity, flexibility, and durability. Below is a structured workflow:
1. Material Selection
- Copper Type: High-purity electrolytic copper (≥99.9% Cu) for optimal conductivity.
- Form: Typically tinned or bare copper strips/braids for flexibility.
2. Cutting & Shearing
- Copper strips/braids are cut to required lengths using precision shearing machines.
- Laser/CNC cutting ensures dimensional accuracy.
3. Surface Treatment (Optional)
- Tinning: Electroplating with tin (Sn) to prevent oxidation.
- Electro-polishing: For improved surface smoothness.
- Cleaning: Degreasing to remove contaminants.
4. Braiding/Layering (For Flexible Sections)
- Multiple thin copper strands are braided or laminated for flexibility.
- Ensures vibration resistance and thermal expansion handling.
5. Terminal Attachment
- Crimping/Welding: Copper lugs or terminals are attached via:
- Ultrasonic welding (for high-current applications).
- Hydraulic crimping (for secure mechanical joints).
- Soldering: For smaller busbars (optional).
6. Insulation (If Required)
- Heat-shrink tubing for partial insulation.
- PVC/Silicone coating for full insulation.
- Epoxy resin for rigid-flex designs.
7. Quality Testing
- Conductivity Test: Measures resistance (Ohm's law).
- Flex Test: Repeated bending to check durability.
- Pull Test: Ensures terminal strength.
- Thermal Imaging: Detects hotspots under load.
8. Final Assembly & Packaging
- Labeling, barcoding, and packaging for shipment.
- Compliance checks (e.g., IEC 60439, UL standards).
