The manufacturing process of copper PV ribbons begins with raw material preparation, where high-purity copper—typically 99.99% oxygen-free—is fed into the production line via a payoff machine. The purity of the copper is a critical factor in determining the quality of the final welding strip.
Next, the ribbons undergo annealing, a heat treatment process that enhances their ductility and flexibility. To improve solderability and prevent oxidation, a tin coating machine applies a uniform layer of tin. The ribbons are then straightened and precisely cut to the required lengths.
Following this, rigorous quality inspections are conducted to ensure optimal conductivity, accurate thickness, and strong coating adhesion. Finally, the finished ribbons are spooled, packaged, and labeled, ensuring they are ready for safe transportation and reliable use in photovoltaic applications.
Copper PV Ribbon Machines: Precision Equipment for Solar Panel Manufacturing
Copper PV ribbon machines are specialized equipment designed for the production of high-performance copper-based PV ribbons used in solar panels. These systems include a payoff machine for feeding raw materials, rolling mills for precise thickness reduction of flat ribbon wires, and annealing furnaces to enhance ductility. Additionally, tin coating systems improve solderability and corrosion resistance, while a take-up machine efficiently packs the finished product. These advanced turnkey manufacturing solutions are essential for producing reliable, high-conductivity interconnect ribbons and busbars, ensuring superior performance in photovoltaic applications.


Advantages of Copper PV Ribbon Machines
1. Efficient Processing: The machine transforms round copper wire into high-quality photovoltaic ribbon through a precise process that includes annealing, cleaning, hot-tin coating, cooling, and precision winding.
2. Superior Coating Quality: Ensures uniform tin coating thickness, a glossy surface, and eliminates defects such as tin beads (slag) and pinholes, guaranteeing stable and reliable quality.
3. User-Friendly Operation: Features an intuitive human-machine interface (HMI) with a built-in round wire mode, making the system easy to operate and control.
4. High Mechanical Performance: Designed for durability, the ribbon maintains a yield strength of ≥56MPa, ensuring excellent mechanical stability and performance in photovoltaic applications.

The speed of PV ribbon machines typically varies between 100 to 500 meters per minute, depending on the machine type and process complexity. Machines optimized for higher efficiency and automation usually operate at the faster end of the spectrum, while those involving more intricate processes, such as coating or precision shaping, may run at slower speeds. Additionally, factors such as the required quality of the ribbons, the materials used, and specific product types (such as fine-sized ribbons, flat wire, busbars, or black ribbons) all influence the speed. The level of automation in the system also plays a significant role in determining production speed.
In photovoltaic ribbon equipment, manufacturers use various types of flux to ensure effective soldering. Rosin flux is commonly chosen for its excellent solderability and minimal residue. On the other hand, water-soluble flux is preferred for its environmental benefits, as it can be easily cleaned after soldering, making it ideal for automated systems. No-clean flux leaves minimal residue and reduces the need for post-production cleaning. For tinning copper ribbons, organic acid flux is frequently used, providing strong solder joints and preventing oxidation. Additionally, activated flux contains chemical activators that remove oxide layers, ensuring a superior bond. The selection of flux depends on the ribbon type, soldering process, and the required level of cleanliness.
