Yong An solder bars are generated under the conditions of using high purity metals and rigorous quality controlled by adding anti-oxidant elements in manufacturing processes to remove the oxidants in solders, and the production rate of the solder splash is reduced to the minimum. Yong An solder bars meet and even surpass the requirements of J-STD-006 &JIS-Z-3282AR standards.
