C"IPC-2581"

D"ODB++"

💡 Hint

Common Mistakes

Using RS-274D which is outdated.

Confusing Gerber format with other PCB file formats.

The standard Gerber file format version used is RS-274X.

medium

Complete the code to set the units for the Gerber file to millimeters.

PCB Design

gerber_file.set_units([1])

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

A"cm"

B"mm"

C"inches"

D"mil"

💡 Hint

Common Mistakes

Using inches instead of millimeters.

Using unsupported units like cm.

Gerber files commonly use mm or inches. Here, millimeters are set with "mm".

hard

Fix the error in the code to correctly add a copper layer to the Gerber file.

PCB Design

gerber_file.add_layer([1])

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

A"drill"

B"solder_mask"

C"silkscreen"

D"copper"

💡 Hint

Common Mistakes

Adding solder mask instead of copper layer.

Using drill layer which is for holes.

The copper layer is added by specifying "copper" as the layer type.

4fill in blank

hard

Fill both blanks to set the aperture size and shape for the Gerber file.

PCB Design

gerber_file.set_aperture([1], [2])

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

A0.25

B0.5

C"circle"

D"rectangle"

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing size and shape values.

Using unsupported aperture shapes.

The aperture size is set to 0.25 mm and the shape is "circle".

5fill in blank

hard

Fill all three blanks to generate the Gerber file with correct filename, format, and precision.

PCB Design

gerber_file.generate(filename=[1], format=[2], precision=[3])

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

A"board_top.gbr"

B"RS-274X"

C4

D"board_bottom.gbr"

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong filename or extension.

Confusing format string with other formats.

Setting precision as string instead of number.

The filename is "board_top.gbr", format is "RS-274X", and precision is set to 4 decimal places.
