Various embodiments of the teachings herein include a method of establishing a solder bond between a first solder partner and a second solder partner with a solder medium including a metallic solder material and a multitude of magnetic nanoparticles. An example method includes: a) generating a magnetic alternating field with a magnet coil acting on the solder medium; b) heating the magnetic nanoparticles via the interaction with the magnetic alternating field; and c) melting the metallic solder material owing to heat transfer from the magnetic nanoparticles to the metallic solder material and thereby forming the solder bond between the first solder partner and the second solder partner with molten metallic solder material.

Disclosed is a component-mounted structure including a first object having a plurality of first electrodes, a second object as an electronic component having second electrodes, a joint portion joining the plurality of first electrodes and the corresponding second electrodes to each other, and a resin-reinforcing portion. The joint portion has a core including at least one of a first metal and a resin particle, and a layer of an intermetallic compound of the first metal and a second metal having a low melting point. The resin-reinforcing portion includes a particulate matter including the core and the intermetallic compound, in a portion except between the first and second electrodes. An amount of the particulate matter included in the portion is 0.1 to 10 vol %.
