Nihon Superior's High Ductility Lead-free Solder Provides High Impact Strength

Mar 06, 2009

OSAKA, JAPAN � March 2009 � Nihon Superior Co. Ltd., a supplier of advanced soldering and brazing materials to the global market, announces SN100C high ductility lead-free solder provides high impact strength. A high ductility solder alloy can absorb more energy during impact than an alloy with high tensile strength but is brittle.

The graphic below shows the stress-strain curves and BGA sphere fracture areas generated by shear impact tests with speeds of (a) 100 mm/sec and (b) 1000 mm/sec on an electroless Ni/Immersion Au surface finish. (The fracture areas are compared to Sn-37Pb normalized to 100 percent).

The fracture area of SN100C is similar to that of Sn-37Pb at the shear speed of 100mm/sec but the fracture area for Sn-3.0Ag-0.5Cu is smaller than Sn-37Pb.

The fracture area of SN100C is slightly smaller than that of Sn-37Pb at the shear speed of 1000 mm/sec, while the Sn-3.0Ag-0.5Cu fracture area is much less than Sn-37Pb due to its low ductility and brittleness. Comparing the fracture areas, Sn-37Pb>SN100C>Sn-3.0Ag-0.5Cu.

In general, a solder alloy with a larger fracture area can absorb greater energy and shock due to its ductility and ability to deform. Additionally, Sn-3.0Ag-0.5Cu is brittle and resistant to deformation, where SN100C is ductile like Sn-37Pb. Furthermore, SN100C(Sn-0.7Cu-0.05Ni+Ge) has no shrinkage defects, reduced copper erosion, and its' high ductility inhibits growth of the IMC layer.
