Circuit Board Inlay Members for Press-Fit Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional circuit structures face misalignment issues due to differences in spacing between press-fit holes on a circuit board and the terminals of electronic components mounted on it.
Innovation Solution
The circuit board design incorporates first and second inlay members with specific end portions and areas, along with resistive patterns, to align and secure electronic components by press-fitting the inlay members into through holes, ensuring proper spacing and reducing misalignment.

Engineering Contradiction Analysis
1Ease of manufacture
If press-fit holes are used to mount electronic components on a circuit board, then manufacturing simplicity is improved, but misalignment occurs when spacing between press-fit holes differs from spacing between component terminals
Solution Approach 1:
The patent introduces inlay members as intermediary components between the press-fit holes and the electronic component terminals. These inlay members have mounting surfaces with precisely positioned through-holes that match the terminal spacing, acting as a mediator that bridges the spacing mismatch between the circuit board press-fit holes and the component terminals, thereby eliminating alignment errors while maintaining the simplicity of press-fit mounting
Solution Approach 2:
The patent segments the mounting structure into multiple independent parts: the circuit board with press-fit holes, the inlay members with precisely positioned through-holes, and the electronic components. This segmentation allows each component to be optimized independently - the circuit board maintains simple press-fit hole spacing while the inlay members provide the precise terminal spacing alignment, resolving the contradiction between manufacturing simplicity and alignment precision

AI summary
A circuit board includes a circuit board main body including a first through hole and a second through hole, a first inlay member inserted into the first through hole, and a second inlay member inserted into the second through hole. A first end surface of the first inlay member includes a first end portion on the side of the second inlay member, a second end portion on the opposite side of the second inlay member, a first area including the first end portion, and a second area including the second end portion. A first end surface of the second inlay member includes a third end portion on the side of the first inlay member, a fourth end portion on the opposite side of the first inlay member, a third area including the third end portion, and a fourth area including the fourth end portion. The circuit board further includes a first resist provided in the second area, and a second resist provided in the fourth area.
