In the context of the increasing internal competition in the photovoltaic industry, the requirements of component companies for welding ribbon materials have long ceased to be just "usable", but to pursue "more stable", "more accurate" and "more economical". Especially with the continuous advancement of high-density welding, high-power output and new packaging technologies,A small-sized copper-clad aluminum flat wire with high stability and precision technology is becoming a key variable on the material side..
andRaytron, is the high-quality provider of this variable.
?? 01. Precision size, adapting to the needs of smaller components
Ruichuang has 13 high-precision rolling equipments, capable of rolling copper-clad aluminum strips starting from 0.05mm.The minimum width is 2mm, the maximum width is 10mm, and the thickness tolerance is controlled within ±0.003mm, providing a perfect match for most fine pitch welding, MBB, TOPCon, HJT and other new battery components.
?? 02. Strong bonding, not easy to delaminate, not afraid of high temperature
Common problems with traditional small-sized copper-clad aluminum welding strips include: the copper layer is too thin, the bonding is not strong, aluminum is exposed during welding, and the rate of strip breakage is high.
Ruichuang's technical team continues to tackle the problem of controlling the bonding strength of the copper-aluminum composite layer.Adopt hot pressing + uniform compound + oxygen-free protective annealing process to ensure that the density, uniformity and adhesion of the copper layer are far higher than the industry average, welding will not delaminate, solder joints will not drift, and component life is more guaranteed.
?? 03. High conductivity, low resistance, higher power generation efficiency
Photovoltaic welding ribbonNot a simple conductive strip, it directly affects the power output of the component.
Ruichuang's small-size copper-clad aluminum flat wire has high outer copper purity and uniform tin plating on the surface.The conductivity can reach 90% IACS or above, effectively reducing resistance loss, while optimizing current path distribution and improving overall cell output efficiency.
?? 04. Stable mass production and fast delivery
Ruichuang not only has advanced equipment, but also pays more attention to management efficiency. The whole process is automated and controlled.Stable daily output and strong batch consistency, ensuring that customers have no worries about mass production projects.
At the same time, the factory always has standard specifications of raw materials in stock.Fastest shipment in 3 days, delivery in 7 days, support flexible customization, making procurement more secure and production more efficient.
? 05. Adapt to various usage scenarios
- High-density MBB battery → can use ultra-thin strips such as 0.1×2mm/0.1×3mm;
- Flexible components/lightweight components → 0.05×5mm lightweight flat wire is preferred;
- Overseas outdoor projects → Customized high anti-oxidation treated copper layer;
- Precision welding scene → The surface tinning process is adjustable to ensure a stable welding temperature range;
