  • Patent number: 9948264
    Abstract: An electronic component includes a spiral or substantially spiral first inductor extending along a stacking direction while turning around a ring-shaped or substantially ring-shaped path. The first inductor includes first inductor conductors and a first interlayer connecting conductor connected to each other. The first interlayer connecting conductor passes through some insulating layers. A second interlayer connecting conductor passes through some insulating layers, and is connected in series and is located within the ring-shaped path.

    Abstract: Embodiments of methods of non-destructively testing whether a laminated substrate satisfies structural requirements are disclosed herein. Additionally, laminated substrates that can be non-destructively tested are also disclosed along with methods of manufacturing the same. To non-destructively test whether the laminated substrates satisfies the structural requirement, an electrical characteristic of the laminated substrate may be detected. Since the detected electrical characteristic is related to a structural characteristic being tested, whether the structural characteristic complies with the structural requirement can be determined based on the electrical characteristic.
