Solution Overview
Problem
Existing multilayer electronic components with built-in inductors and multilayer LC components require complex redesign and process changes to adjust magnetic field coupling, involving changes to via-hole conductor distances or addition of new conductors, which is operationally cumbersome.
Innovation Solution
A multilayer electronic component design featuring two different distances between interlayer connection conductors allows for adjustable magnetic field coupling by varying the lengths of these conductors, enabling easy control of coupling between inductors without the need for extensive redesign or process changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the distance between via-hole conductors is adjusted or a new via-hole conductor is added to control magnetic field coupling, then the desired characteristic is obtained, but the operation becomes very complicated requiring redesign of punching programs, resetting of punching apparatus, and manufacture of new metal molds
Solution Approach 1:
The patent applies parameter changes by varying the distance between interlayer connection conductors in different insulating layers. Specifically, the first and second interlayer connection conductors are spaced by a first distance, while the third and fourth interlayer connection conductors are spaced by a second distance different from the first. This allows control of magnetic field coupling characteristics through geometric parameter variation rather than process redesign.
Solution Approach 2:
The patent segments the inductor structure into multiple interlayer connection conductors distributed across different insulating layers. By dividing the inductor into segments (first, second, third, and fourth interlayer connection conductors) with different spacing arrangements, the magnetic field coupling characteristics can be controlled without requiring complete redesign of the entire via-hole conductor system.
2Adaptability or versatility
If the distance between via-hole conductors is adjusted to control magnetic field coupling, then the coupling degree is controlled, but extensive redesign and process changes are required
Solution Approach 1:
The patent enables adaptable magnetic field coupling control by implementing different spacing parameters for different sets of interlayer connection conductors. The first distance between the first and second conductors differs from the second distance between the third and fourth conductors, providing manufacturing flexibility without requiring complex process changes or new equipment setup.

AI summary
A multilayer electronic component and a multilayer electronic component manufacturing method are capable of easily controlling the degree of magnetic field coupling between inductors. Via-hole conductors are arranged so that they extend in a lamination direction in a laminate, and function as a first inductor. Via-hole conductors are arranged so that they extend in the lamination direction in the laminate, and function as a second inductor. A first capacitor and the first inductor define a first resonance circuit. A second capacitor and the second inductor define a second resonance circuit. The via-hole conductors are arranged in a first insulating layer so that they are spaced apart from each other by a first distance. The via-hole conductors are arranged in a second insulating layer so that they are spaced apart from each other by a second distance that is different from the first distance.
