Minimum trace width and spacing in PCB Design - Dashboard Guide

Dashboard Mode - Minimum trace width and spacing

Goal

Understand how minimum trace width and spacing affect PCB manufacturing quality and electrical performance.

Sample Data

Trace ID	Trace Width (mil)	Trace Spacing (mil)	Current Capacity (A)	Signal Type	Layer
T1	6	6	1.2	Power	Top
T2	4	4	0.8	Signal	Inner
T3	8	6	1.5	Power	Bottom
T4	3	3	0.5	Signal	Top
T5	5	5	1.0	Power	Inner

Dashboard Components

• KPI Card: Minimum Trace Width - Shows the smallest trace width in the data.
  Formula: MIN([Trace Width (mil)]) = 3 mil
• KPI Card: Minimum Trace Spacing - Shows the smallest spacing between traces.
  Formula: MIN([Trace Spacing (mil)]) = 3 mil
• Bar Chart: Trace Width by Trace ID - Displays trace widths for each trace.
• Bar Chart: Trace Spacing by Trace ID - Displays spacing for each trace.
• Table: Trace Details - Shows all columns from the sample data.

Dashboard Layout

+----------------------+----------------------+
| Minimum Trace Width   | Minimum Trace Spacing |
|       (KPI)          |        (KPI)          |
+----------------------+----------------------+
|  Trace Width by Trace ID (Bar Chart)          |
|  Trace Spacing by Trace ID (Bar Chart)        |
+-----------------------------------------------+
|                 Trace Details Table            |
+-----------------------------------------------+
    

Interactivity

Filter by Signal Type (Power or Signal) or Layer (Top, Inner, Bottom) to update all components:

• KPI cards recalculate minimum width and spacing for the filtered traces.
• Bar charts update to show only filtered traces.
• Trace details table shows only filtered rows.

Self Check

If you add a filter for Signal Type = Power, which components update and what changes?

• Minimum Trace Width KPI updates to minimum width among power traces (5 mil).
• Minimum Trace Spacing KPI updates to minimum spacing among power traces (5 mil).
• Bar charts show only power traces (T1, T3, T5).
• Trace details table shows only power traces.

Key Result

Dashboard shows minimum trace width and spacing with visual and tabular details filtered by signal type and layer.
