The application of the present disclosure greatly improves production efficiency, and can completely replace manual operation.

A wire wound-type coil component with an integrated structure does not have a bonding portion where there is concern about reliability with respect to a spiral conductive wire, a terminal electrode, and an annular core. A coil component includes a core with an integrated structure, at least part of which is a winding core portion, which has an annular shape having a through-hole, and which is made of a non-conductive material; and a coil conductor with an integrated structure, which has a spiral conductive wire arranged to spirally extend around the winding core portion and first and second terminal electrodes formed at both end portions of the spiral conductive wire, respectively. The coil component is manufactured through three-dimensionally shaping the core, the coil conductor, and a shape holding member for holding a shape of a wall surface of the core defining the through-hole, by using a 3D printer.

The present invention relates to a method for producing a pole core (1), comprising the following method steps: providing a magnetic workpiece (10), which has a first side (11) and a second side (12), the first side (11) having a groove (15) directed toward the second side (12); inserting at least two inserts (20) and at least one bonding means (25) into the groove (15), the at least one bonding means (25) being arranged between the two inserts (20); and integrally bonding the at least two inserts (20) to each other and/or the at least two inserts (20) to the workpiece (10).

The present disclosure is related to an electronic module assembly structure including a system board, an electronic module and an adhesive material. The system board includes a first upper surface and a first lower surface opposite to each other. The electronic module spatially corresponds to the first upper surface and includes plurality leading pins and a carrier. Each leading pin has a soldering surface and is connected to the first upper surface through a first reflow soldering process. When the plurality leading pins are connected to the first upper surface, a height difference is formed between the carrying surface of the carrier and the soldering surfaces. The adhesive material is disposed on the carrying surface or the first upper surface. The carrier is connected with the first upper surface through the adhesive material, so that the electronic module is fixed to the first upper surface through the adhesive material.
