Common Mistakes

Choosing a text or image file format instead of Gerber.

The Gerber file format (.gerber) is the standard output file used in PCB fabrication. It contains the necessary layer information for manufacturing.

Complete the code to include the drill file in the fabrication output.

PCB Design

fabrication_files = ['board.gbr', [1]]

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

💡 Hint

Common Mistakes

Using document or image file extensions instead of drill file.

The drill file (.drl) specifies the holes to be drilled in the PCB and is essential for fabrication.

💡 Hint

Common Mistakes

Including document or spreadsheet files instead of Gerber layers.

The 'board.gbl' file represents the bottom copper layer Gerber file, which is necessary for fabrication.

4fill in blank

hard

Fill both blanks to correctly generate the list of essential fabrication files.

PCB Design

fabrication_files = ['board[1]', 'board[2]']

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

💡 Hint

Common Mistakes

Using document or text file extensions instead of Gerber layers.

The '.gts' and '.gto' files represent the top solder mask and top silkscreen layers respectively, both required for PCB fabrication.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping fabrication file types to their extensions.

PCB Design

fab_files = {'copper_top': 'board[1]', 'copper_bottom': 'board[2]', 'drill': 'board[3]'}

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

💡 Hint

Common Mistakes

Using document or image file extensions instead of fabrication files.

The top copper layer uses '.gtl', bottom copper uses '.gbl', and drill files use '.drl' extensions, all essential for fabrication.
