Abstract Scope |
The aim of this study was to show the effect of aging time, temperature and Na addition to eutectic SnZn on the kinetics of formation and growth of the Cu5Zn8 and CuZn4 phases on Cu substrate. After a wetting test, the samples were aged at different temperatures for different times. Analysis of the microstructure of a cross section of the connection showed an NaZn13 phase in the solder matrix, which can reduce the diffusion rate of Zn atoms to the interface.
