    摘要: PROBLEM TO BE SOLVED: To provide a flux in which the cracks of the flux residue can be suppressed, and which also has satisfactory solder wettability even in high temperature soldering, and to provide a solder composition.SOLUTION: A flux includes at least one polybutadiene (meth)acrylate compound selected from a group consisting of specified polybutadiene (meth)acrylate compounds and hydrogenated dimer acid. Cracks are hard to be generated in the residue flux after soldering, and also, satisfactory solder wettability can be exhibited even if reflow heating under high temperature preheating is performed in an air atmosphere.
