Study on soldering flux used for Sn-07Cu welding wire
- 材料学院－会议论文 
The wettability and corrosiveness of some organic acids were tested to choose an appropriate activator. Then orthogonal design method was used to determine the proportion among the components of the activator. At last a certain amount of water-white rosin was added to further optimize the dispensation. The final soldering flux for Sn-0.7Cu welding wire caters to the demands of welding process such as good weld ability, good liquidity, less smoke, full and shiny welding spot. ? 2011 IEEE.
