    摘要: Provided is a flux which can remove metal oxides to improve solder wettability and can fix the object to be soldered with flux residue. The flux contains thermosetting resin, and long-chain dibasic acid mixture including one or more species of first long-chain dibasic acid having an alkyl group in a side chain, the first long-chain dibasic acid being added as a hardening agent for hardening the thermosetting resin and an activator, and second long-chain dibasic acid having an alkyl group and an alkoxycarbonyl group in a side chain and having carbon number of 8 or more in a main chain between the carboxyl groups at opposite terminals. It is preferable that content of the thermosetting resin is 30 % through 70 % and content of the long-chain dibasic acid mixture is 20 % through 60 %.

    摘要: Provided are: a resin composition for soldering use, which has excellent compatibility with a rosin-based resin and excellent temperature cycle reliability and is therefore suitable for a flux for soldering use; and a soldering composition and a flux cored solder, in each of which the resin composition for soldering use is used. The resin composition for soldering use comprises: an acrylic resin having a number average molecular weight of 500 or more and less than 2000 as determined by mass spectrometry using a time-of-flight mass spectrometer; and a rosin-based resin, a polyethylene-based resin or a polypropylene-based resin. Alternatively, the resin composition for soldering use comprises: an acrylic resin having a weight average molecular weight of 500 or more and less than 2000 as determined by mass spectrometry using a time-of-flight mass spectrometer; and a rosin-based resin, a polyethylene-based resin or a polypropylene-based resin.

    摘要: A purpose of the present invention is to provide a flux having an improved cleaning property by suppressing a carbonization of a flux residue.
    A flux contains an organic acid, a thixotropic agent, rosin and a solvent wherein a fatty acid monoalkylol amide having 14-20 carbon atoms is contained as the thixotropic agent. The fatty acid monoethanol amide is added in an amount of 3-10% by weight as the thixotropic agent. In addition, a dicarboxylic acid having 10 or less carbon atoms is added in an amount of 4-10% by weight as the organic acid. Moreover, the solvent is added in an amount of 30-60% by weight.
