Solder wire
   
Sn-Cu/Sn-Ag-Cu Series alloys
Lead-free solder wire  
     
 

Sn-Cu/Sn-Ag-Cu alloy solder is refined from new casting technology and high purity raw materials and is applied to manual soldering with strict environmental requirements.

 

Using scientific flux formula, it has the characteristics of good fluidity, small smoke and less spatter.
