Abstract:The impact behavior of solder joints was studied using three different highvelocity impact tests: the U-notch Charpy impact test, the no-notch Charpy impact test, and a laboratory-designed drop test. The solder joints were made of five solder alloys, Sn-37Pb, Sn-3.8Ag-0.7Cu, Sn-2.0Ag-0.7Cu, Sn-1.0Ag-0.7Cu, and Sn-0.7Ag-0.7Cu (in wt.%), in which the traditional Cu/solder/Cu butt joint was used. All three impact tests gave the same trend of the impact behavior of the solder joints, with the Sn-37Pb joints having… 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.
