This product is mainly made of premium hydrogenated rosin and high-purity refined tin, using internationally advanced composite multi-component active flux formula, combined with modern production technology, strict quality control process, and perfect testing system for careful manufacturing. The product complies with and exceeds the requirements of the EU RoHS directive.

Product features:

• The distribution of flux is uniform, with a deviation of ≤ 0.1%;

• Excellent wettability and fast welding speed;

• The welding points are beautiful and the welding quality is reliable.

This product is suitable for the capacitor manufacturing industry and can directly achieve soft soldering connection on the zinc coating and gold alloy coating on the end face of the capacitor. It is especially suitable for welding difficult to weld metal base materials, such as nickel plated parts, galvanized parts, Dumei wire, beryllium bronze, etc.
