An electronic component includes a component body including a mounting surface facing a circuit substrate, and a plurality of first external electrodes arranged on the mounting surface so as to extend between a first side and a second side of the mounting surface substantially parallel with each other and so as to be within a first region having a width that is substantially equal to half a length of the first side in a direction in which the first side extends. A circuit substrate includes a substrate body, a plurality of second external electrodes, arranged on a main surface of the substrate body, respectively connected to the plurality of the first external electrodes, and support units arranged to protrude from the main surface of the substrate body and such that the electronic component overlaps the support units outside the first region.

A layered inductor 10 is manufactured by layering “silver-based conductive layers” and “ferrite-based magnetic layers” and simultaneously firing these layers. The conductive layers are via-connected to form a helical coil 30. A shape of a cross sectional surface of the conductive layer, cut by a plane perpendicular to a longitudinal direction of each of the conductive layers is a substantial trapezoid shape, having an upper base and a lower base. A base angle θ of the trapezoid shape at both ends of the lower base is equal to or greater than 50° and is smaller than or equal to 80°.

A nanoparticle for conductive ink including a ferromagnetic core and a conductive layer surrounding the ferromagnetic core. The ferromagnetic core is 5 to 40 parts by weight, per 100 parts by weight of the nanoparticles. The conductive ink provides electrical reliability by allowing a uniform distribution of nanoparticles in ejected ink and prevents the coffee stain phenomenon and migration.

摘要:
Printed circuit boards and breadboard devices have contact pads and magnetic component connectors where connection between the contact pads and the magnetic component connectors are made by magnetic force. Either the contact pad or the magnetic component connector will be magnetic and the other will be made of a material to which a magnet will be attracted. For example, printed circuit boards, which usually have copper traces, include contact pads made of a material to which a magnet will be attracted. Circuit components are connected to magnetic component connectors having magnetic legs which then connect the components to the contact pads of the circuit board or breadboard device. This makes the connection of components to a printed circuit board or breadboard device fast and easy and provides for easy removal and replacement of components. Magnetic component connectors can also be configured to connect magnetically to one another.
