Conduction Inspection Jig With High Flexural Strength Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conduction inspection jigs face issues with probe bending and stress distribution during electrical inspection of printed wiring boards, leading to potential breakage of inspection components due to uneven load distribution and inadequate flexural strength.
Innovation Solution
A conduction inspection jig design featuring a first member with a flexural strength of 300 MPa or higher, a second member with similar strength, and a support member forming a space between them, with probes penetrating through openings in both members to ensure even stress distribution and prevent breakage during inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional inspection jigs are used, then the inspection can be performed, but the probe bends and causes uneven stress distribution leading to breakage of inspection components
Solution Approach 1:
The patent changes the material parameter of the first and second members from conventional materials to materials with a flexural strength of 300 MPa or higher. This parameter change enables the members to withstand the bending stress from probes during inspection without breaking, thereby resolving the contradiction between inspection reliability and component strength.
2Volume of moving object
If the first member and second member are positioned close together, then the inspection jig is compact, but the probe experiences uneven stress distribution and may break the members
Solution Approach 1:
The patent maintains close positioning of the first and second members for compactness while simultaneously changing the material parameter to achieve 300 MPa or higher flexural strength. This allows the members to be positioned close together without compromising their ability to withstand probe-induced stress, thus resolving the contradiction between compactness and breakage resistance.

AI summary
A conduction inspection jig includes a first member having first openings and a flexural strength of 300 MPa or higher, a second member having second openings and positioned above the first member, a support member positioned between the first member and the second member such that the support member is forming a space between the first member and the second member, and a probe that is positioned in one of the first openings in the first member and one of the second openings in the second member such that the probe penetrates through the one of the first openings, the space formed between the first member and the second member, and the one of the second openings and has a first end portion protruding from the first member and a second end portion protruding from the second member on the opposite side with respect to the first end portion.
