Wiring Circuit Board Joint Layout for Stable Inspection Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiring circuit boards suffer from low handleability during inspection due to unstable posture of the mounting portion caused by the frame's movement, which is not adequately supported by the supporting member with low resilience.
Innovation Solution
A method for producing a wiring circuit board involving a frame, mounting portion, and joints, where the mounting portion is supported by both a first and second joint, with the first joint being longer and more resilient, and the second joint being shorter and more rigid, allowing for stable posture and correction of swing during inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a supporting member with low resilience is used to correct swing, then swing correction is achieved, but the mounting portion posture becomes unstable during inspection
Solution Approach 1:
The supporting member is divided into two separate joints: a first joint with low resilience for swing correction and a second joint with high resilience for stable support during inspection. This segmentation allows each joint to perform its specific function optimally without interfering with the other.
Solution Approach 2:
Different resilience characteristics are assigned to different parts of the supporting structure. The first joint has low resilience to enable swing correction, while the second joint has high resilience to provide stable support during inspection, creating local quality variations that satisfy different functional requirements.
2Stability of the object's composition
If the first joint is made longer to improve low resilience, then swing correction is enhanced, but the structural rigidity decreases
Solution Approach 1:
The supporting function is segmented into two joints with different length and rigidity characteristics. The longer first joint provides low resilience for swing correction, while the shorter second joint provides high rigidity for stable support, allowing both requirements to be satisfied simultaneously.
Solution Approach 2:
Different local regions of the supporting structure have different mechanical properties. The first joint is designed with higher length-to-rigidity ratio for swing correction, while the second joint is designed with lower length-to-rigidity ratio for stable support, creating local quality variations that meet different functional needs.

AI summary
A method for producing a product board includes a first step, a second step, and a third step in order. In the first step, an intermediate board including a frame, a mounting portion, a first joint, and a second joint is prepared. The mounting portion is surrounded by the frame. The mounting portion is spaced apart from the frame. The first joint and the second joint connect the frame to the mounting portion. Each of the frame, the mounting portion, and the first joint in the intermediate board includes a base insulating layer and a wiring layer. The wiring layer is disposed on one surface of the base insulating layer in a thickness direction. In the second step, the intermediate board is inspected. In the third step, the second joint is removed.
