Inductor Component Shared Vertical Wiring Terminal Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing inductor components face challenges in reducing size due to the large number of outer terminals required, which limits design flexibility and increases complexity.
Innovation Solution
The inductor component design includes first and second inductor wiring lines within a magnetic layer, with vertical wiring lines penetrating through the magnetic layer and exposed on the surface, allowing for a shared connection of second vertical wiring lines to reduce the number of externally exposed terminals, thereby increasing design freedom and enabling smaller component sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of outer terminals is increased to connect all ends of inductor wiring lines, then the connectivity and functionality are improved, but the design freedom decreases and the component size increases
Solution Approach 1:
The patent merges multiple second vertical wiring lines into a single shared wiring line that connects to multiple second end portions of inductor wiring lines. This consolidation reduces the number of outer terminals from six (two for each of three inductor wiring lines) to four (one first vertical wiring line, one shared second vertical wiring line, and two third vertical wiring lines), thereby reducing design complexity while maintaining full connectivity functionality.
2Reliability
If the number of outer terminals is increased to ensure proper connections, then the electrical connectivity is improved, but the component area increases making size reduction difficult
Solution Approach 1:
The patent combines multiple connection functions into a single shared second vertical wiring line that serves multiple second end portions of inductor wiring lines. This merging approach reduces the total number of outer terminals required, thereby reducing the component area occupied by terminals and enabling size reduction while maintaining proper electrical connectivity across all inductor wiring lines.
3Reliability
If more vertical wiring lines are provided for each inductor wiring line end, then the connection reliability is improved, but the number of externally exposed terminals increases reducing design freedom
Solution Approach 1:
The patent merges multiple individual vertical wiring lines into a shared second vertical wiring line that connects to multiple second end portions. This consolidation maintains connection reliability by ensuring proper electrical connection to all inductor wiring lines while reducing the number of externally exposed terminals, thereby increasing design freedom and flexibility in substrate layout and terminal arrangement.
