| dc.description.abstract | The bond shear test was used to assess the integrity of Sn-0 7Cu and Sn-0 3Ag-0 7Cu lead-free solder alloy drops solidified on copper substrates with smooth and rough surface finishes. Solder alloys solidified on smooth substrates required higher shear force compared to that on rough substrates. Sn-0 3Ag-0 7Cu alloy required higher shear energy than Sn-0 7Cu alloy. Solder alloys solidified on smooth substrate surfaces exhibited complete ductile failure. On rough copper surfaces, solder alloys showed a transition ridge characterized by sheared intermetallic compounds (IMCs) and the presence of dimples. The peak shear strength decreased with increase in contact area of the solder bond on the substrate. Smooth surface and the presence of minor amount of Ag in the solder alloy enhance the integrity of the solder joint. 2013 Institute of Materials, Minerals and Mining. | en_US |
