S01XBIG58-M500-4

Sn 0.1Ag 0.7Cu 1.6Bi + Ni

The only difference from SAC305 is "low cost"

A very small amount of two modifying elements Bi and Ni are added. Different effects from these 

elements achieved strong and easy-to-use low Ag solder that is equivalent to or superior to SAC305, such 

as the melting point, thermal resistance, and time-dependent change in crystal structures.Click here for the

 mechanism of hybrid reinforcement.

Maintains thermal-fatigue resistance for a long time

IMCs containing Ni (yellow points in he diagram on the left) finely disperse among Sn crystals and 

prevents growth of Sn crystals due to thermal shocks. Therefore, S1XBIG/S01XBIG makes a clear distinction

 from SAC305 also for its "long-lasting robustness" not just temporary withstandability.

Achieved both low-Ag and halogen-free

KOKI strives to respond to customers' requests for cost cutting and to become, as a company 

that sets a high value on environmental conservation, a good partner of all customers who are 

considerate to the environment. Therefore, all our low Ag products have halogen free versions in

 their line-up.
