Product Features
Low corrosion of copper
High purity refined tin smelting
Oxide, less tin residue
Low surface tension
High conductivity
Low tin slag
Increase productivity
Quick package, good wettability
When the chain speed was increased from 70cm/min to 90cm/min, a significant difference appeared. First of all, the fluidity of the solder is significantly improved, so that the solder covers the solder joint more evenly, improving the welding quality. Secondly, the residence time of the solder on the welding surface is shortened, which reduces the chance of oxidation and ensures the reliability of the solder joint. At the same time, due to the increased fluidity of the solder, the temperature of the tin furnace can be lower, reducing the formation of tin slag, which helps to maintain a clean welding environment. In addition, the reduction in welding time increases the production speed and reduces the use of energy and materials, thus reducing costs. Overall, increasing chain speed improves many aspects of the welding process, improving quality, efficiency, and reducing costs.
Applicable to the industry
Widely used in precision electronic instruments, precision medical equipment, high-end electronic products, automotive electronics and other products manual dip welding and wave soldering; After adding a trace amount of precious metal elements to match, the developed solder bar products are also suitable for manual dip welding and wave soldering of electronic component feet, wire materials, PCB plates and other products.
