Silkscreen placement rules in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to ensure silkscreen does not overlap pads.

    remove_overlap()

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

💡 Hint

Common Mistakes

Using '<=' would remove silkscreen when there is no overlap.

Overlap area greater than 0 means silkscreen overlaps pad; remove overlap.

2fill in blank

medium

Complete the code to check minimum clearance between silkscreen and pads.

PCB Design

if clearance [1] minimum_clearance:
    adjust_silkscreen()

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

C==

D>=

💡 Hint

Common Mistakes

Using '>=' misses cases where clearance is too small.

Clearance less than minimum requires silkscreen adjustment.

Fix the error in the silkscreen placement condition.

💡 Hint

Common Mistakes

Using 'overlaps' allows silkscreen on pads.

Silkscreen should be kept only if it does not overlap the pad.

4fill in blank

hard

Fill both blanks to set silkscreen clearance and remove overlaps.

PCB Design

if silkscreen_clearance [1] minimum_clearance and silkscreen [2] pad:
    remove_silkscreen()

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

A<

B>

Ddoes_not_overlap

Attempts:

💡 Hint

Common Mistakes

Using '>' for clearance or 'does_not_overlap' causes wrong removal.

Remove silkscreen if clearance is less than minimum and it overlaps pad.

5fill in blank

hard

Fill all three blanks to define silkscreen placement rules in code.

PCB Design

if silkscreen [1] pad and clearance [2] minimum_clearance and silkscreen [3] keep_area:
    place_silkscreen()

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

C<=

💡 Hint

Common Mistakes

Using 'overlaps' or wrong comparison operators causes errors.

Silkscreen is placed if it does not overlap pad, clearance is at least minimum, and it fits in keep area.
