The nanoparticles of tin-silver solder, Sn-3.5Ag, of necklace geometry were made in a swirl batch. It was found that the addition of the element, Ag, did not vary the microstructure of the solder matrix, but Ag simply diluted into the Sn matrix randomly. The swirl flow facilitated the formation of particles with different sizes. It was found that the size distribution of the nanoparticles was strongly related to the height in the swirl batch. In addition, the aggregation of the nanoparticles was explored and the dispersion of the nanoparticles was achieved by adjusting the pH value of the solution near the neutral value.
