Layer transition strategy in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a via that connects two layers.

PCB Design

via = create_via(start_layer=[1], end_layer='Layer2')

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

A'Layer5'

B'Layer1'

C'Layer4'

D'Layer3'

💡 Hint

Common Mistakes

Choosing a layer that does not exist in the stack.

The via must start from 'Layer1' to connect properly to 'Layer2'.

2fill in blank

medium

Complete the code to set the via diameter for a layer transition.

PCB Design

via.set_diameter([1])

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

A0.5

B0.8

C0.3

D1.0

💡 Hint

Common Mistakes

Using too small or too large diameter causing manufacturing issues.

A diameter of 0.5 mm is standard for reliable layer transitions.

3fill in blank

hard

Fix the error in the code to correctly create a blind via from top to inner layer.

PCB Design

blind_via = create_via(start_layer='Top', end_layer=[1])

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

A'Top'

B'Bottom'

C'Inner3'

D'Inner2'

Attempts:

💡 Hint

Common Mistakes

Setting end_layer to 'Bottom' creates a through via instead of blind.

A blind via connects the top layer to an inner layer like 'Inner2', not to the bottom or the same layer.

4fill in blank

hard

Fill both blanks to define a microvia connecting top and inner layers with correct drill size.

PCB Design

microvia = create_via(start_layer=[1], end_layer=[2])
microvia.set_drill_size(0.[3])

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

A'Top'

B'Inner1'

C3

D5

💡 Hint

Common Mistakes

Using drill size too large for microvias.

Microvias typically connect 'Top' to 'Inner1' with a drill size of 0.3 mm.

5fill in blank

hard

Fill all three blanks to create a via with correct start layer, end layer, and plating type.

PCB Design

via = create_via(start_layer=[1], end_layer=[2])
via.set_plating('[3]')

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

A'Inner2'

B'Bottom'

CElectroless

D'Top'

Attempts:

3 left

💡 Hint

Common Mistakes

Incorrect plating type or layer selection.

The via starts at 'Top', ends at 'Bottom', and uses 'Electroless' plating for conductivity.
