Engineering Contradiction Analysis
1Area of moving object
If signal conductive areas are arranged closely to increase integration density, then device miniaturization is improved, but shielding performance deteriorates
Solution Approach 1:
Ground conductive areas are introduced as intermediary elements between adjacent signal conductive areas. These ground areas act as shielding mediators that intercept electromagnetic interference and provide a reference potential, thereby improving shielding performance without reducing the integration density of signal areas.
Solution Approach 2:
The conductive area layout is segmented into distinct functional zones: signal conductive areas for signal transmission and ground conductive areas for shielding. This segmentation allows independent optimization of signal density and shielding effectiveness by strategically distributing ground areas between signal groups.
2Object-affected harmful factors
If ground conductive areas are added to improve shielding, then shielding performance is improved, but device complexity increases
Solution Approach 1:
Ground conductive areas are strategically placed only in specific locations where shielding is most needed—between adjacent signal conductive areas. This localized approach provides effective shielding while minimizing the overall complexity compared to a complete ground shield.
Solution Approach 2:
The ground conductive areas are electrically connected to form a unified shielding network that works collectively to protect signal areas. This merging creates a coordinated shielding system that achieves better performance with simpler individual elements.

AI summary
A circuit board includes a first signal conductive area, a second signal conductive area, a first ground conductive area and a second ground conductive area. The first signal conductive area and the second signal conductive area both extend along a first direction. The first ground conductive area and the second ground conductive area are located on two sides of the first signal conductive area and the second signal conductive area, respectively, thereby improving shielding effect.
