Abstract: The flux according to the present invention includes a fatty acid amide; a first solvent having a temperature, at which its mass measured by thermogravimetry at a nitrogen flow rate of 0.2 to 0.3 L per minute and a temperature increase rate of 10° C. per minute becomes zero, of from 180° C. to lower than 260° C.; and a second solvent having a temperature, at which its mass measured by thermogravimetry at a nitrogen flow rate of 0.2 to 0.3 L per minute and a temperature increase rate of 10° C. per minute becomes zero, of from 100° C. to lower than 220° C. The flux has a content of the first solvent that is lower than a content of the second solvent. The flux does not include reducing agents for reduction removal of surface oxide films of solder, and does not include activators for improving reducibility.

Abstract: The object of the present invention is to provide a solder paste that enables to form a surface mounting structure for electronic components that exhibits crack resistance in a solder joint section even in 100 heat-shock cycles at −40° C. to 150° C. as required for use in the vicinity of engines for vehicular applications. A flux including an amine halogen salt and a dicarboxylic acid is kneaded with a Sn—Ag—Bi—In alloy powder. As a result, a solder paste exhibiting long continuous printability, little occurrence of solder balls, and excellent joining ability with no cracking in 100 heat-shock cycles at −40° C. to 150° C. is obtained.
