Product Introduction
The alloy ratio of this type of tin wire is Sn99.3%Cu0.7%,which is cost-effective, low residue and transparent colorless.Less smoke, no toxic volatile gas suitable for high quality requirements of a variety of automatic soldering machine soldering and manual soldering operations.
1. High cost performance: Lead-free cored tin copper tin wire has a higher cost performance compared with other solder wires, can achieve better welding results, and the price is relatively low.
2. Low residue: The solder wire produces less residue during the welding process, which will not have a negative impact on the welded joint and improve the welding quality and reliability.
3. Transparent and colorless: During the welding process, the melting state of the solder wire is transparent and colorless, and the welding process is more clearly visible, which is easy for the welder to operate and control.
4. Less smoke: Because lead-free cartridge tin copper tin wire does not contain harmful substances, the smoke generated during welding is less, reducing the harm to welders and environmental pollution.
This lead-free solder wire not only features a fast soldering speed, minimal splashing, bright solder joints, low smoke emission, and high insulation resistance but also provides dual functionality for rapid soldering of both copper and nickel materials. With slight adjustments in the production process, the developed Automatic Soldering Machine Welding Special Rosin Core Tin Wire Sn99.3Cu0.7 can be seamlessly integrated into automatic soldering machine operations, significantly enhancing the versatility of this lead-free solder wire.
Adding convenience to customers' production processes, this product is perfectly suited to meet the rapid development needs of modern electronics industries and welding processes. After years of practice and application, it has been recognized by well-known enterprises. Customers can use this product with confidence knowing it meets high standards of quality and performance.
By incorporating this advanced lead-free rosin core tin wire into your manufacturing processes, you ensure efficient and reliable results that align with contemporary industry demands while maintaining environmental responsibility.
