Card Edge Connector Solder Layout for Lower Signal Crosstalk

The patent applies dimensionality change by transitioning from a single-row terminal arrangement to a two-dimensional grid arrangement where terminals are organized in multiple rows and columns. Specifically, signal terminals and grounding terminals are placed in alternating positions within the same row, creating a layered spatial structure that reduces electromagnetic coupling between adjacent signal terminals while maintaining manufacturing simplicity through standardized offset leg configurations.

The patent introduces grounding terminals as intermediary elements positioned between signal terminals. These grounding terminals act as electromagnetic shields that intercept and redirect electromagnetic fields, preventing direct coupling between adjacent signal terminals. The offset leg structure of grounding terminals further enhances this shielding effect by creating additional spatial separation and field distortion paths.

The patent applies local quality by differentiating the spatial arrangement and leg configurations of different terminal types within the same connector. Signal terminals have specific offset distances and orientations, while grounding terminals have different offset parameters. This localized differentiation optimizes each terminal type's electromagnetic characteristics while maintaining overall assembly ease through standardized manufacturing processes.

The patent employs asymmetry in the leg offset configurations of terminals. Rather than symmetric arrangements, the patent uses asymmetric offset distances and angles for signal terminals versus grounding terminals. This asymmetric design creates unequal electromagnetic field distribution that reduces coupling between signal terminals while the standardized asymmetric patterns maintain ease of assembly through consistent manufacturing procedures.
