Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connection devices for measuring electrical characteristics of inspection objects face issues with increased complexity and manufacturing costs due to the high number of connection wires required between the space transformer and the electrode substrate, which complicates the flow of resin and increases manufacturing steps.
Innovation Solution
The electrical connection device incorporates a space transformer with a short-circuit wiring pattern on its first main surface, connecting same-potential probes to reduce the number of connection wires needed, thereby simplifying the connection between the space transformer and the electrode substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of terminals on the space transformer is made the same as the number of probes, then each probe can be individually connected to the electrode substrate, but the number of connection wires increases and manufacturing complexity increases
Solution Approach 1:
The patent merges multiple connection wires that connect to the same potential electrode pads into a single bundled connection wire. This reduces the total number of connection wires from the number of probes to a smaller number corresponding to the number of electrode pads, thereby simplifying the connection structure while maintaining reliable electrical connections.
Solution Approach 2:
The invention makes a single connection wire serve multiple functions by having it connect to multiple electrode pads that are at the same potential. This multi-functional approach allows one connection wire to replace what would traditionally require multiple separate wires, reducing overall complexity.
2Manufacturing precision
If the number of connection wires is increased to match the number of probes, then each probe connection is individually established, but the resin flow becomes difficult and manufacturing steps increase
Solution Approach 1:
By bundling multiple connection wires into a single unit, the invention creates more space around the bundled wire for resin to flow. This merging approach reduces the cumulative space occupation of individual wires, allowing resin to properly fill and fix the connection wires during the encapsulation process.
3Adaptability or versatility
If the number of connection wires increases with the number of probes, then complete probe coverage is achieved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent combines multiple connection wires into bundled units, where each bundle corresponds to electrode pads at the same potential. This merging reduces the total wire count while maintaining the ability to connect all probes to the electrode substrate, thereby reducing manufacturing complexity without sacrificing adaptability.
