| 简介 | A lead free solder consisting of a ternary eutectic composition of Sn-3.9Ag-0.7Cu with Ce in the amount of 0.5 to 2% by weight exhibits improved oxidation resistance increased ductility in comparison with other RE metals and is characterized by a homogeneous mixture of large grain CeSn3 intermetallics in a Sn beta phase. In solder applications, the joints with the solder are resistance to interfacial fracture by distributing the strain within the solder interface increasing impact resistance. | ||
