PROBLEM TO BE SOLVED: To provide flux for solder capable of reducing the amount of white smoke generated during a soldering time, having sufficient wettability, and capable of preventing deposition of a raw material in flux during a flux manufacturing.SOLUTION: There is provided flux for resin flux cored solder containing 30 mass% or more and 80 mass% or less rosin ester, and 5 mass% or more and 15 mass% or less activator. Preferably, the total of a base material containing the rosin ester is 85 mass% or more and 95 mass% or less.SELECTED DRAWING: None |
