The urgency of researching on lead-free technology is introduced since lead-free manufacture has been spread. The soldering experiment on several kinds of package resistances and capacitances is made. Contrast and analyze the shearing performance, the effects of boding time on improving the quality of solders are summarized. By observing the pictures of bad solders, the factors of soldering time on improving solder quality are elaborated. Under the condition of this experiment, prolonging bonding time suitably can improve the solder quality.
