Abstract
Cu contents in pure Sn and Sn-37Pb solders were measured as a function of reflowing time. The results
indicated that the contents are significantly higher than that of the Cu solubility limit in each solder. Several
plausible causes for the excess dissolution of Cu into the solders were explored with experimental observations.
