Aluminum Ribbons
Bimetallic Ribbons
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.

Our PV ribbon line produces a wide range of interconnect ribbons and busbars, typically 0.6 mm to 8 mm wide and 0.1 mm to 0.5 mm thick. We apply a 20-micron thick solder coating to the ribbons, with a tolerance of ±3 microns. The line also allows us to manufacture ribbons with various yield strengths—Rp0.2% below 60 MPa, 70 MPa, or 80 MPa, and in some special cases, even below 50 MPa—to meet different customer requirements.
