Via stitching for ground planes in PCB Design - Dashboard Guide

Dashboard Mode - Via stitching for ground planes

Goal

Understand how via stitching improves ground plane performance in PCB designs by analyzing via count, placement, and impact on signal integrity.

Sample Data

Layer	Via Count	Via Spacing (mm)	Ground Plane Area (cm²)	Signal Integrity Score
Top	50	5	100	85
Inner 1	70	4	120	90
Inner 2	65	4.5	110	88
Bottom	55	5.5	105	83
Test Layer	30	7	80	75

Dashboard Components

• KPI Card: Total Via Count = 270 (Sum of Via Count across all layers)
• KPI Card: Average Via Spacing = 5 mm (Average of Via Spacing)
• Bar Chart: Via Count by Layer (shows via count for each layer)
• Line Chart: Signal Integrity Score by Layer (shows signal integrity scores)
• Table: Detailed Layer Data (shows all columns from sample data)

Interactivity

A filter for Layer allows selecting one or multiple layers. When a layer is selected, all components update to show data only for those layers. For example, selecting "Top" and "Bottom" layers updates the KPI cards, bar chart, line chart, and table to reflect only those layers' data.

Self Check

If you add a filter to show only the "Inner 1" layer, which components update and what is the new Total Via Count?

Answer: All components update. The Total Via Count KPI shows 70, the Average Via Spacing KPI shows 4 mm, the charts and table show data only for "Inner 1".

Key Result

Dashboard shows via stitching details by PCB layer including via counts, spacing, and signal integrity scores.
