Design Rules Check (DRC) setup in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the minimum clearance rule in the DRC setup.

PCB Design

drc.set_minimum_clearance([1])

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

A0.35

B0.45

C0.25

D0.15

💡 Hint

Common Mistakes

Using a clearance value that is too small causing potential shorts.

Using a clearance value that is too large reducing PCB density.

The minimum clearance is commonly set to 0.25 mm to ensure safe spacing between traces.

Complete the code to enable the DRC rule for minimum trace width.

PCB Design

drc.enable_rule('[1]')

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

💡 Hint

Common Mistakes

Enabling the wrong rule such as max_trace_width which is not a DRC check.

Using a rule name that does not exist in the DRC setup.

Enabling the 'min_trace_width' rule ensures traces do not go below the minimum width set.

3fill in blank

hard

Fix the error in the code to set the via drill size in the DRC.

PCB Design

drc.set_via_drill_size([1])

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

A0.6mm

B'0.6mm'

C"0.6"

D0.6

Attempts:

💡 Hint

Common Mistakes

Including units like 'mm' inside the parameter.

Passing the size as a string instead of a number.

The drill size should be a numeric value without units for the function to accept it correctly.

4fill in blank

hard

Fill both blanks to set the minimum annular ring and enable its DRC rule.

PCB Design

drc.set_min_annular_ring([1])
drc.enable_rule('[2]')

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

A0.15

Bmin_annular_ring

Cmin_via_drill

D0.25

Attempts:

💡 Hint

Common Mistakes

Confusing annular ring with drill size.

Enabling the wrong rule name.

Setting the minimum annular ring to 0.15 mm and enabling the 'min_annular_ring' rule ensures proper via pad size.

5fill in blank

hard

Fill all three blanks to set the minimum solder mask clearance, enable its rule, and set the clearance value.

PCB Design

drc.enable_rule('[1]')
drc.set_solder_mask_clearance([2])
drc.set_rule_clearance('[3]', [2])

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

Amin_solder_mask_clearance

B0.1

Dmin_trace_clearance

Attempts:

💡 Hint

Common Mistakes

Using different rule names inconsistently.

Setting clearance values too large or too small.

Enabling the 'min_solder_mask_clearance' rule, setting the clearance to 0.1 mm, and applying it to the same rule ensures solder mask spacing is checked.
