Abstract:ARTICLES YOU MAY BE INTERESTED INAbstract. This study investigates the effects of Si particles addition into a Sn-Cu-Ni lead-free solder paste on its microstructure and mechanical properties. The Sn-Cu-Ni-Si composite solder pastes were prepared by mechanically mixing Si particles into Sn-Cu-Ni solder paste. From microstructure observation, it was found that the area of β-Sn has decrease and the bulk microstructure has been refined. The result for shear test indicates that composite solder joint exhibited high… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
