Abstract

Characteristic studies were carried out to analyze 5 different types of lead free solder alloy. The concentrations of Pb, Cu, Fe, Ag and Ni in selected lead-free solders were determined by spark emission spectrometry and ICP-OES while their wettability were demonstrated by wetting balance. The Pb content found is well below the limit set in the Restriction of Hazardous Substances (0.1%). Subsequent statistical analysis revealed that there are five distinctive clusters of solders corresponding to their elemental contents, where the concentrations of Cu, Ag and Ni are the main discriminants.
