Common Mistakes

Confusing footprint with symbol

Using physical layout terms

The symbol represents the logical component, so it is named by the component name.

2fill in blank

medium

Complete the code to assign a footprint to a component symbol.

PCB Design

symbol.assign_footprint([1])

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

💡 Hint

Common Mistakes

Using symbol name instead of footprint

Confusing pin count with footprint

The footprint is the physical layout pattern assigned to the symbol.

3fill in blank

hard

Fix the error in the code to link symbol and footprint correctly.

PCB Design

component = Symbol([1])
component.set_footprint('R_0805')

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

💡 Hint

Common Mistakes

Passing footprint name to Symbol constructor

Confusing footprint and symbol

The Symbol constructor needs the component name, not the footprint name.

4fill in blank

hard

Fill both blanks to create a symbol and assign its footprint.

PCB Design

symbol = Symbol([1])
symbol.[2]('QFN-32')

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

💡 Hint

Common Mistakes

Using footprint name as symbol name

Wrong method to assign footprint

Create the symbol with the component name, then assign the footprint using set_footprint.

5fill in blank

hard

Fill all three blanks to define a symbol, assign a footprint, and set pin count.

PCB Design

symbol = Symbol([1])
symbol.[2]([3])
symbol.pin_count = 16

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

💡 Hint

Common Mistakes

Using wrong method to assign footprint

Passing component name instead of footprint name

First, create the symbol with the component name, then assign the footprint using set_footprint with the footprint name.
