Lead-free pure tin balls (tin hemispheres) are manufactured and produced for the needs of domestic electroplating manufacturers and microelectronic packaging operations. The pure tin is refined by high-purity electrolysis, and the production process has undergone strict quality control. Due to the high composition, the content of impurities is extremely low, and The alloy structure is fine, so the conductivity is good, the cleaning performance is uniform, and it provides an excellent electroplating effect.
