Highly thermal stress resistant alloy with indium
Increasing demand for high thermal stress durability
For PCBs exposed to severe temperature fluctuation, long term durable alloys are required to counter thermal cycling induced stress.
■ Mechanism of crack occurrence by thermal cycling stress

Absorption of mechanical stress by addition of indium
SB6N58 M500S1 adopted 6% indium to balance and optimize thermal stress and deformation character̶ istics, which could occur if excessively added.
■ Difference of deformation temperature by Indium content
