A copper wire tin plating machine is specialized industrial equipment designed to coat oxygen-free copper wire with a thin layer of tin alloy Sn60Pb40. This tinning process significantly improves the wire’s performance in electrical and electronic applications by enhancing conductivity, corrosion resistance, and solderability. The typical tin coating thickness on one side is around 15 microns, and the final wire diameter generally ranges from 0.18 mm to 0.4 mm.
Sky Bluer Environmental designs, manufactures, and supplies a complete range of equipment, including copper wire tin plating machines, PV ribbon machines (lead or lead-free), bus ribbon machines, fine wire drawing machines, rolling mills, and more. We also offer the most common styles for different countries, such as British, Indonesia, Malaysia, Germany, Switzerland, Sweden, Australia,Turkey, American, Australian, Japanese, Italian,Indian styles, etc.
This advanced equipment is designed to convert round copper wire into photovoltaic ribbons, allowing seamless processing of round wire, flat ribbon wire, and segmented round wire. Its versatile design supports both round and flat wire applications.
Key features include precise take-up reed movement for stable wire handling, an automatic bobbin change system to reduce downtime, fully automatic wire threading to improve efficiency, and complete automation of bobbin loading unloading and placement to minimize manual labor and boost productivity.This equipment delivers reliable performance and flexibility, making it well suited for high volume photovoltaic ribbon production.
This is the first part of the copper wire tin plating machine. Its function is to draw large-diameter copper wire into a thinner size. The input wire diameter is typically up to 1.2 millimeters.
The dual rolling machine is designed to convert round copper wire into flat wire. It is offered as an optional solution for users with specific flat wire orders and also targets a growing potential market.
All of our new copper wire tin alloy plating machines are equipped with induction annealing systems. This method uses non-contact heating, which is especially effective for fine wire diameters. The equipment is properly grounded to reduce the risk of electric shock for operators. The annealing process runs at a constant speed, ensuring stable operation and consistent product quality.
Yes, Sn60Pb40 (which means 60% tin and 40% lead) has traditionally been a standard solder alloy used in photovoltaic (PV) ribbon wire production. This alloy offers good solderability, mechanical strength, and reliable electrical conductivity.
However, due to environmental and health regulations—such as the RoHS directive—many manufacturers have shifted towards lead-free alternatives (e.g., Sn99.3Cu0.7 or Sn96.5Ag3.0Cu0.5) in recent years.
If you’re working with traditional PV ribbon manufacturing or certain legacy systems, Sn60Pb40 may still be common, but the industry trend is moving toward lead-free alloys for better environmental compliance.
The machine frame is built as a gantry with both horizontal and vertical supports to ensure the wire remains stable during the tinning process. This copper wire tinning machine applies a thin layer of tin alloy, typically Sn60Pb40 (60% tin, 40% lead), to the copper wire.
Photovoltaic welding ribbon, also known as tinned copper ribbon or tin-coated copper strip, is a critical material used in the interconnection of solar cells within photovoltaic (PV) modules. It is typically classified into busbars (current collecting tape) and interconnect ribbons, both essential for conducting electricity between cells.
As a key component in the PV module soldering process, the quality of the welding tape directly influences the current collection efficiency and overall output power of the solar module. Reliable and secure soldering is crucial—poor-quality tape or improper bonding can result in false welding, leading to reduced performance or failure.
When selecting welding tape, it’s important to match its characteristics with those of the solar cells being used. In general:
Choosing the appropriate welding tape ensures optimal electrical performance and long-term reliability of PV modules.
