摘要： Disclosed is a solder paste that includes, within a flux, an activator that has: a dibasic acid with a molecular weight of no more than 250, a monobasic acid with a molecular weight in the range of 150 to 300, and a dibasic acid with a molecular weight in the range of 300 to 600; and at least one resin additive that is selected from among the group comprising high-density polyethylenes and polypropylenes. The solder paste has in the range of 4 wt% to 12 wt% resin additive within the flux, and the viscosity of the solder paste at 80°C is at least 400 Pa·s.

摘要： Disclosed is a solder paste which has adequate fluidity even after a shear force is repeatedly applied thereto by a screen printing method or the like. Specifically disclosed is a flux for a solder paste, which contains: an acrylic resin that is obtained by radically copolymerizing a (meth)acrylic acid ester having a C 6 -C 15 alkyl group and a (meth)acrylic acid ester other than the above-mentioned (meth)acrylic acid ester; and a rosin. When the weight of the rosin is taken as 1, the weight ratio of the acrylic resin is 0.5-1.2 (inclusive), and the flux for a solder paste is fluidized by the application of a shear force of 10-150 Pa (inclusive).

摘要： The present invention is a solder paste that contains no reducing agents or activators, and a method for producing a soldered product for completing solder joints using the solder paste. This solder paste for a reduction gas is used together with a reducing gas, wherein: the solder paste contains a solder powder, a thixotropic agent that is solid at normal temperature, and a solvent; and contains no reducing agents for removing oxidized films or activators for improving reduction properties.
