Manual trace routing in PCB Design - Dashboard Guide

Dashboard Mode - Manual trace routing

Goal

Understand how manual trace routing affects PCB design quality and production time.

Sample Data

Trace ID	Length (mm)	Number of Bends	Layer	Routing Time (min)	Signal Integrity Score
T1	50	3	Top	15	8.5
T2	70	5	Bottom	20	7.8
T3	40	2	Top	12	9.0
T4	60	4	Inner	18	8.0
T5	55	3	Bottom	16	8.3
T6	65	6	Top	22	7.5

Dashboard Components

• Total Routing Time: Sum of all routing times.
  Formula: Total Routing Time = SUM([Routing Time (min)])
  Result: 103 minutes
• Average Signal Integrity Score: Average of signal integrity scores.
  Formula: Average Signal Integrity = AVERAGE([Signal Integrity Score])
  Result: 8.18
• Trace Length vs Routing Time Scatter Plot: X-axis is Trace Length (mm), Y-axis is Routing Time (min). Each point is a trace.
• Number of Bends by Layer Bar Chart: Shows total bends per layer.
  Calculation:
  Top: 3 + 2 + 6 = 11 bends
  Bottom: 5 + 3 = 8 bends
  Inner: 4 bends
• Trace Details Table: Shows all columns from sample data for detailed review.

Interactivity

Filter by Layer: Selecting a layer (Top, Bottom, Inner) updates all components to show data only for that layer.

Hover on scatter plot points highlights the corresponding trace in the details table.

Self Check

If you filter for Layer = 'Top', which components update?

• Total Routing Time updates to 49 minutes (15 + 12 + 22)
• Average Signal Integrity updates to 8.33 ((8.5 + 9.0 + 7.5) / 3)
• Scatter plot shows only Top layer traces
• Number of Bends by Layer bar chart updates to show only Top layer bends (11 bends)
• Trace Details Table shows only Top layer traces (T1, T3, T6)

Key Result

Dashboard shows manual trace routing metrics including total routing time, signal integrity, bends by layer, and trace details.
