Thermal spoke connections in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a thermal spoke connection with correct clearance.

PCB Design

thermal_spoke = ThermalSpoke(clearance=[1])

💡 Hint

Common Mistakes

Choosing too small clearance causing shorts

Choosing too large clearance reducing heat dissipation

The standard clearance for thermal spokes is typically 0.5mm to balance heat dissipation and manufacturability.

medium

Complete the code to set the number of thermal spokes in a connection.

PCB Design

thermal_spoke.set_spokes(count=[1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using too few spokes reducing heat dissipation

Using too many spokes complicating layout

Four spokes are commonly used to provide balanced heat flow and mechanical stability.

3fill in blank

hard

Fix the error in the code to correctly create a thermal spoke with width 0.3mm.

PCB Design

thermal_spoke = ThermalSpoke(width=[1])

Drag options to blanks, or click blank then click option'

A0.03mm

B0.3mm

C3mm

D30mm

💡 Hint

Common Mistakes

Using 0.03mm which is too thin

Using 3mm or 30mm which are too wide

The correct width for a thermal spoke is 0.3mm to ensure proper heat conduction without risking damage.

4fill in blank

hard

Fill both blanks to define a thermal spoke with 4 spokes and 0.5mm clearance.

PCB Design

thermal_spoke = ThermalSpoke(spokes=[1], clearance=[2])

Drag options to blanks, or click blank then click option'

B0.3mm

C0.5mm

💡 Hint

Common Mistakes

Mixing clearance and spoke count values

Choosing incorrect clearance values

Four spokes and 0.5mm clearance are standard values for thermal spokes to balance heat and manufacturability.

5fill in blank

hard

Fill all three blanks to create a thermal spoke with 4 spokes, 0.3mm width, and 0.5mm clearance.

PCB Design

thermal_spoke = ThermalSpoke(spokes=[1], width=[2], clearance=[3])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Swapping width and clearance values

Using wrong spoke count

This configuration uses 4 spokes, 0.3mm width, and 0.5mm clearance for optimal thermal performance.
