Abstract
A precise and efficient method to analyze surface oxide using FTIR and electrochemical reduction was successfully developed in this study. Systematic analyses on surface oxide layer of commercial Cu-Fe-Zn-P (C194) lead frames demonstrate that this integrated analytical method can be applied to decide the variation in oxide type from top surface to subsurface and corresponding layer thickness. The results turned out to be in good agreement with XPS and TEM data.
