Production Process

The reason why copper foil flexible connections can be widely used in the market is driven by research and development in the following aspects:

● Market demand:With the rapid development of new energy vehicles and energy storage technology, higher requirements have been put forward for the connection between batteries, electronic control systems and other components.

● Power equipment requirements:Especially high-current switchgear, transformers and bus ducts, etc., have extremely high requirements for the performance and reliability of connections.

● Materials Research: Develop copper foil materials with higher purity and higher conductivity, and study copper foil surface treatment technology to improve the oxidation resistance and contact properties of the connections.

● Process optimization: Develop more advanced welding technologies, such as ultrasonic welding and laser welding, to achieve smaller, more precise connections and improve production efficiency and product consistency.

● Structural design: For different application scenarios, various structural forms of copper foil soft connections, such as bifurcated soft connections, woven soft connections, etc., have been developed to meet various complex connection requirements.

● Product testing and verification: Establish a complete testing system to conduct DC resistance testing, temperature rise testing, bending fatigue testing and earthquake testing on soft connections to ensure that products can operate stably and reliably in various extreme environments.

With the rapid development of new energy vehicles and energy storage technology, higher requirements have been put forward for the connection between batteries, electronic control systems and other components.
● High current density:Fast charging and high-power output of new energy vehicles require connections that can withstand high currents, and copper foil soft connections can provide excellent electrical conductivity.
● Shock absorption and fatigue resistance:The battery pack will be subject to vibration and impact while the vehicle is driving, and traditional hard connections are easy to break. The flexibility of the copper foil soft connection can effectively absorb vibration and extend service life.
● Lightweight:Compared with traditional cables, copper foil soft connections can achieve smaller size and lighter weight while meeting the same conductivity requirements, helping to improve vehicle cruising range.
● Power equipment:Especially high-current switchgear, transformers and bus ducts, etc., have extremely high requirements for the performance and reliability of connections.
● High reliability:The copper foil soft connection achieves a firm bond between molecules through pressure welding and other processes, with small contact resistance and low temperature rise, which greatly improves the reliability of the equipment.
● Easy installation:Copper foil soft connections can be customized according to the shape and size of the equipment to facilitate installation and maintenance.
● Heat dissipation performance:Copper foil has excellent thermal conductivity and can effectively conduct the heat generated at the connection to avoid overheating of the equipment.
