Zone properties configuration in PCB Design - Real Business Scenario

Scenario Mode

👤 Your Role: You are a PCB design engineer working on a new circuit board layout.

📋 Request: Your manager wants you to configure copper zones on the PCB to optimize signal integrity and thermal management.

📊 Data: You have a PCB layout file with multiple layers and components placed. The data includes zone areas, net assignments, clearance rules, and thermal relief settings.

🎯 Deliverable: Produce a report showing the configured zone properties for each copper zone, including net assignment, clearance, fill type, and thermal relief settings.

Sample Data

Zone ID	Layer	Net Name	Area (mm²)	Clearance (mm)	Fill Type	Thermal Relief
1	Top Layer	GND	1500	0.2	Solid	Enabled
2	Bottom Layer	VCC	1200	0.15	Hatchet	Disabled
3	Inner Layer 1	GND	1800	0.25	Solid	Enabled
4	Inner Layer 2	Signal1	900	0.2	Hatchet	Enabled
5	Top Layer	Signal2	700	0.2	Solid	Disabled
6	Bottom Layer	GND	1600	0.15	Solid	Enabled

1

Step 1: Open the PCB design software and load the layout file.

No formula needed; just open the file.

Expected Result

PCB layout with all zones visible on their respective layers.

2

Step 2: Select Zone ID 1 on the Top Layer and configure its properties.

Set Net Name = 'GND', Clearance = 0.2 mm, Fill Type = 'Solid', Thermal Relief = 'Enabled'.

Expected Result

Zone 1 configured with correct net, clearance, fill, and thermal relief.

3

Step 3: Configure Zone ID 2 on the Bottom Layer with the given properties.

Set Net Name = 'VCC', Clearance = 0.15 mm, Fill Type = 'Hatchet', Thermal Relief = 'Disabled'.

Expected Result

Zone 2 configured as specified.

4

Step 4: Repeat configuration for Zone ID 3 on Inner Layer 1.

Set Net Name = 'GND', Clearance = 0.25 mm, Fill Type = 'Solid', Thermal Relief = 'Enabled'.

Expected Result

Zone 3 configured correctly.

5

Step 5: Configure Zone ID 4 on Inner Layer 2.

Set Net Name = 'Signal1', Clearance = 0.2 mm, Fill Type = 'Hatchet', Thermal Relief = 'Enabled'.

Expected Result

Zone 4 configured as requested.

6

Step 6: Configure Zone ID 5 on Top Layer.

Set Net Name = 'Signal2', Clearance = 0.2 mm, Fill Type = 'Solid', Thermal Relief = 'Disabled'.

Expected Result

Zone 5 configured properly.

7

Step 7: Configure Zone ID 6 on Bottom Layer.

Set Net Name = 'GND', Clearance = 0.15 mm, Fill Type = 'Solid', Thermal Relief = 'Enabled'.

Expected Result

Zone 6 configured correctly.

8

Step 8: Generate a report listing all zone properties for review.

Export zone properties table with columns: Zone ID, Layer, Net Name, Area, Clearance, Fill Type, Thermal Relief.

Expected Result

Report generated showing all configured zone properties.

Final Result

-------------------------------------------------------------
| Zone ID | Layer        | Net     | Area | Clearance | Fill Type | Thermal Relief |
|---------|--------------|---------|------|-----------|-----------|---------------|
| 1       | Top Layer    | GND     | 1500 | 0.2 mm    | Solid     | Enabled       |
| 2       | Bottom Layer | VCC     | 1200 | 0.15 mm   | Hatchet   | Disabled      |
| 3       | Inner Layer 1| GND     | 1800 | 0.25 mm   | Solid     | Enabled       |
| 4       | Inner Layer 2| Signal1 | 900  | 0.2 mm    | Hatchet   | Enabled       |
| 5       | Top Layer    | Signal2 | 700  | 0.2 mm    | Solid     | Disabled      |
| 6       | Bottom Layer | GND     | 1600 | 0.15 mm   | Solid     | Enabled       |
-------------------------------------------------------------

✓GND zones use solid fill with thermal relief enabled for better grounding and heat dissipation.

✓VCC zone uses hatchet fill with thermal relief disabled to reduce impedance.

✓Signal zones have appropriate clearance and fill types to maintain signal integrity.

Bonus Challenge

Optimize the thermal relief settings to balance heat dissipation and manufacturability for all zones.

Show Hint

Consider enabling thermal relief on power nets and disabling on sensitive signal nets to improve performance.
