Au10Sn90

 Features:                                                  


-Eutectic solder, melting point 217°C

-Good wettability

-Lower cost than Au80Sn20







Description                                                     


 Au10Sn90 is a eutectic lead-free solder alloy with a eutectic temperature of 217°C and good wetting properties. Due to the low Au content, the cost is lower than that of Au80Sn20, and it is used in low temperature wafer level packaging and other fields.
