Wiring Board Partitioned Opening for Component Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring boards face challenges in preventing electronic components from making contact with each other, leading to potential short circuits, especially when they are densely packed in a shared opening portion of the substrate.
Innovation Solution
The solution involves forming a substrate with a partially partitioned opening portion and protrusions on the wall surfaces to keep electronic components separated, along with an insulation layer and conductive layers to ensure reliable electrical connections and prevent short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electronic components are accommodated in an opening portion of a substrate, then the wiring board achieves compact configuration and high integration, but the electronic components may make contact with each other causing short circuits
Solution Approach 1:
The opening portion of the substrate is divided into multiple regions by protrusions extending from the wall surface. These protrusions partition the space to accommodate multiple electronic components while maintaining physical separation between them, preventing contact and short circuits while enabling compact arrangement.
Solution Approach 2:
Protrusions are introduced as intermediary structures between adjacent electronic components. These protrusions act as physical barriers that maintain separation between components, ensuring reliable operation while allowing dense packing within the opening portion.
2Volume of moving object
If electronic components are positioned closely to achieve miniaturization, then the wiring board becomes more compact, but the components become unstable and may shift position
Solution Approach 1:
The opening portion is segmented into distinct accommodation regions by protrusions. Each region independently holds an electronic component in a fixed position, providing stability even when components are densely arranged. The protrusions create defined spaces that prevent component shift during assembly and operation.
Solution Approach 2:
The protrusions are pre-formed on the wall surface of the opening portion before electronic components are mounted. This preliminary structuring of the accommodation space ensures that components are guided into correct positions and maintained stably during the assembly process and subsequent handling.
3Ease of manufacture
If traditional insulation methods are used without wall surface partitions, then the manufacturing process is simpler, but electronic components cannot be effectively separated
Solution Approach 1:
The wall surface of the opening portion is segmented by adding protrusions that extend into the accommodation space. This segmentation creates natural separation barriers for electronic components, improving reliability without requiring complex external fixtures or additional separation mechanisms.
Solution Approach 2:
The protrusions serve multiple functions simultaneously: they partition the opening portion to prevent component contact, provide positional reference during assembly, and maintain separation during operation. This multi-functionality achieves reliable component separation without significantly increasing manufacturing complexity.

AI summary
A wiring board includes a substrate having an opening portion, multiple electronic devices positioned in the opening portion such that the electronic devices are arrayed in the lateral direction of each of the electronic devices, and an insulation layer formed on the substrate such that the insulation layer covers the electronic devices in the opening portion of the substrate. The substrate has a wall surface defining the opening portion and formed such that the opening portion is partially partitioned and the electronic devices are kept from making contact with each other.
