Rc. Reno et al., A MOSSBAUER STUDY OF TIN-BASED INTERMETALLICS FORMED DURING THE MANUFACTURE OF DISPERSION-STRENGTHENED COMPOSITE SOLDERS, Journal of electronic materials, 26(1), 1997, pp. 11-15
Mossbauer spectroscopy was used to characterize dispersion-strengthene
d composite solder powders that were formed through hot gas spray atom
ization. To perform quantitative measurements, we first measured the r
elative recoilless fractions of eutectic solder and three intermetalli
c compounds: Cu3Sn, Cu6Sn5, and Ni3Sn4. These results were then used t
o determine the concentrations of intermetallic species present in var
ious composite solder samples. Mossbauer spectroscopy was shown to be
an effective:tool in the analysis of dispersion-strengthened composite
solders and was preferentially sensitive to the presence of tin-based
intermetallics and oxides.
