Manufacturing constraints awareness in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to calculate the total number of layers in a PCB design.

PCB Design

total_layers = [1] + 2

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

Asignal_layers

Bcore_layers

Ccopper_layers

Ddrill_layers

💡 Hint

Common Mistakes

Using core_layers instead of signal_layers

Confusing drill_layers with signal layers

The total number of layers includes the signal layers plus 2 outer layers.

2fill in blank

medium

Complete the code to filter components that exceed the maximum allowed height for manufacturing.

PCB Design

tall_components = [c for c in components if c.height [1] max_height]

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

A<=

B==

C>

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using <= instead of >

Using == which only matches exact height

We want components taller than the maximum allowed height, so we use >.

3fill in blank

hard

Fix the error in the code that calculates the minimum drill hole diameter allowed.

PCB Design

min_drill = min([hole.diameter for hole in holes if hole.diameter [1] min_diameter])

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

A>=

B<

C==

D<=

Attempts:

3 left

💡 Hint

Common Mistakes

Using < which filters smaller holes

Using == which filters only exact matches

We want holes with diameter greater than or equal to the minimum diameter allowed.

4fill in blank

hard

Fill both blanks to create a dictionary of components with their widths, filtering only those wider than the minimum width.

PCB Design

component_widths = {c.name: c.width for c in components if c.width [1] [2]

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

A>

B<

Cmin_width

Dmax_width

Attempts:

3 left

💡 Hint

Common Mistakes

Using < instead of >

Using max_width instead of min_width

We want components with width greater than the minimum width, so use > and min_width.

5fill in blank

hard

Fill all three blanks to create a summary dictionary of components with their heights, filtering those within allowed height range.

PCB Design

allowed_components = {c.id: c.height for c in components if c.height [1] [2] and c.height [3] max_height}

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

A>=

Bmin_height

C<=

Dmax_height

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect operators like < or > for range checks

Mixing up min_height and max_height variables

The code filters components with height greater than or equal to min_height and less than or equal to max_height.
