Zone priority for overlapping fills in PCB Design - Dashboard Guide

Dashboard Mode - Zone priority for overlapping fills

Business Question

Which copper fill zones take priority when they overlap on a PCB design, and how does this affect the final copper coverage?

Sample Data: Copper Fill Zones

Zone ID	Net Name	Area (mm²)	Priority	Overlap With	Effective Area (mm²)
Z1	GND	150	1	Z2	130
Z2	VCC	120	2	Z1	20
Z3	Signal	80	3	None	80
Z4	GND	60	1	Z3	60
Z5	VCC	40	2	Z4	10

Dashboard Components

• KPI Card: Total Copper Area
  Formula: SUM of all Zone Areas = 150 + 120 + 80 + 60 + 40 = 450 mm²
• KPI Card: Total Effective Copper Area
  Formula: SUM of Effective Areas = 130 + 20 + 80 + 60 + 10 = 300 mm²
• Bar Chart: Zone Areas by Priority
  Shows total area per priority level:
  Priority 1: 150 + 60 = 210 mm²
  Priority 2: 120 + 40 = 160 mm²
  Priority 3: 80 mm²
• Stacked Bar Chart: Overlapping Areas by Zone
  Shows how much area is overlapped and effective:
  Z1: 150 total, 130 effective (overlap with Z2)
  Z2: 120 total, 20 effective (overlapped by Z1)
  Z4: 60 total, 60 effective (overlap with Z3)
  Z5: 40 total, 10 effective (overlapped by Z4)
• Table: Zone Details
  Shows all columns from sample data for detailed review.

Interactivity

User can filter by Net Name (e.g., GND, VCC, Signal). Filtering updates all components to show only zones of the selected net.

Filtering by Priority updates the bar charts and KPIs to reflect only zones with that priority.

Hovering over bars in charts highlights corresponding rows in the Zone Details table for easy comparison.

Self Check

If you add a filter for Net Name = GND, which components update and what changes occur?

• KPIs update to sum only GND zones: Total Area = 150 + 60 = 210 mm²; Effective Area = 130 + 60 = 190 mm².
• Bar Chart shows only Priority 1 zones with areas 210 mm².
• Stacked Bar Chart shows overlapping details only for Z1 and Z4.
• Zone Details table filters to show only Z1 and Z4 rows.

Key Result

Dashboard shows copper fill zone areas, their overlapping priorities, and effective copper coverage on a PCB.
