An inductor component comprising a base body including first and second magnetic layers laminated in order along a first direction; and an inductor wire between the first and second magnetic layers and on a plane that is orthogonal to the first direction. The first magnetic layer is in a reverse direction to the first direction of the inductor wire, the second magnetic layer is in the first direction of the inductor wire and in a direction that is orthogonal to the first direction, and when a main surface of the second magnetic layer is viewed from a direction which is orthogonal to the main surface of the second magnetic layer in the first direction, the second magnetic layer includes a dark region corresponding to the inductor wire and a bright region whose brightness is higher than that of the dark region.

The invention comprises a method of: providing an inductor core, placing a winding guide within an inch of the inductor core, positioning a first turn element with the winding guide, positioning a second turn element with the winding guide, and mechanically coupling the first turn element to the second turn element to form at least a part of a winding, the winding forming a wrapped shape about the inductor core. Optionally and preferably, turn elements are subsequently joined, mechanically coupled, and/or welded together to form sections of the winding.

A coil component has a magnetic element body made of resin containing magnetic particles, a coil part embedded in the magnetic element body, conductor posts which are embedded in the magnetic element body and whose one ends are connected to the coil part and the other ends are exposed from the magnetic element body, an insulating layer interposed between the conductor posts and the magnetic element body, and other insulating layers interposed between the coil part and the magnetic element body. Since the insulating layer is interposed between the conductor posts and the magnetic element body, it is possible to ensure insulation performance between the conductor posts and the magnetic element body and to prevent the occurrence of peeling therebetween.

To improve magnetic characteristics of a coil component having a structure in which an interlayer insulating film is provided between a spiral coil pattern and a magnetic element body. A coil component 1 includes: an interlayer insulating film 41 covering coil patterns CP1 to CP3 from one side in the axial direction of the coil patterns; a magnetic element body M1 filled in the inner diameter areas of the coil patterns CP1 to CP3; and a magnetic element body M2 covering the coil patterns CP1 to CP3 from the one side in the axial direction through the interlayer insulating film 41. The interlayer insulating film 41 has a protruding part 41A radially protruding to the inner diameter area, and the protruding part 41A is curved to the other side in the axial direction. Since the protruding part 41A is curved in the axial direction, the entrance of a magnetic path passing through the inner diameter area is made wider than when the protruding part 41A linearly protrudes to the inner diameter area. This suppresses deterioration in magnetic characteristics due to the presence of the protruding part 41A.

The magnetic inlay is configured so that, depending on the geometrical properties of the electrically conductive structure, a specific inductance value is provided for the magnetic inlay.

A component carrier includes a stack with at least one electrically insulating layer structure, a structured electrically conductive layer assembled to the stack, where a part of the structured electrically conductive layer is configured as an inductive element, and a magnetic matrix embedded in the stack. The magnetic matrix at least partially surrounds the inductive element. Further, a manufacturing method is described.

Systems and methods of additively manufacturing passive electronic components are provided. An additive manufacturing device may deposit a material to create a passive electronic component. A sensor may continuously measure an electrical property of the passive electronic component across two electrical contacts as the material is deposited during manufacturing. The sensor may transmit the measured electrical property to a processor whereby the processor may adjust a material deposition rate of the additive manufacturing device. The continuous measurement of the electrical property and adjustment of the material deposition rate as the passive electronic component is produced allows for passive electronic components to be manufactured to a high degree of accuracy of the electrical property.
