Web2. mar 2024 · The results show that the Cu 6 Sn 5 grain morphology is affected by the solder composition and the reflow time. The Cu 6 Sn 5 grain size decreases upon addition of TiO 2 and shows a significant decrease when the TiO 2 nanoparticle fraction is increased to 0.1 wt %. At higher TiO 2 nanoparticle fractions, the Cu 6 Sn 5 grain size increases slightly.
