摘要: A flux for a solder paste according to an aspect of the invention includes an acrylic resin obtained by radically copolymerizing a (meth)acrylate having a C6-C15 alkyl group and a (meth)acrylate other than the above-mentioned (meth)acrylate; and rosins. The weight ratio of the acrylic resin is 0.5 or greater and 1.2 or less when the weight of the rosins is taken as 1, and the flux for a solder paste is fluidized by application of a shear force of 10 Pa or greater and 150 Pa or less.

摘要: A soldering flux contains a base resin and an activating agent. The base resin contains a thermoplastic acrylic resin having a glass transition temperature of below −50° C. This enables to sufficiently suppress the occurrence of cracks in the flux residue after soldering, under the severe environment where the temperature difference is extremely large. The soldering flux has high reliability and excellent solderability, and is conventional with respect to the load against manufacturing cost and environment.

摘要: A resistor with a thermal fuse includes: a substrate consisting of an insulating material; a wire pattern formed on a surface of the substrate; a gap for electrically cutting off the wire pattern; a plate spring consisting of an electrically conductive material arranged across the gap; an electrically conductive member fixed to one end of the plate spring on a side of the wire pattern and having approximately the same linear conduction coefficient as that of the substrate; a first low melting point alloy for welding the electrically conductive material and the wire pattern provided on one side of the gap; a second low melting point alloy for welding the other end of the plate spring and the wire pattern provided on the other side of the gap; wherein, when the first low melting point alloy is melted, the electrically conductive member is released from the first low melting point alloy so that the plate spring is also released from the wire pattern.
