Common Mistakes

Choosing a BOM or document file instead of the PCB design file.

Using a file extension that is not related to manufacturing data.

The manufacturing file for PCB design typically has a .pcb extension. Opening design_file.pcb allows you to review the manufacturing data.

Common Mistakes

Selecting copper or silkscreen layers instead of drill.

Using incorrect layer names that cause errors.

The drill layer contains the holes to be drilled in the PCB. Using get_layer('drill') extracts this important manufacturing layer.

Fix the error in the code to correctly check if the manufacturing file has a soldermask layer.

💡 Hint

Common Mistakes

Using underscores or dashes in the layer name.

Capitalizing parts of the layer name incorrectly.

The standard layer name for soldermask is 'soldermask' without underscores or dashes. Using the exact name ensures the check works correctly.

Fill both blanks to create a dictionary of layer names and their file extensions for export.

PCB Design

export_files = {'copper': '[1]', 'drill': '[2]'}

💡 Hint

Common Mistakes

Mixing up file extensions for copper and drill layers.

Using generic or incorrect file extensions.

Copper layers are usually exported as .gbr files, and drill layers as .drl files for manufacturing.

5fill in blank

hard

Fill all three blanks to filter layers for export that are either copper or soldermask.

PCB Design

export_layers = {layer: data for layer, data in manufacturing_file.layers.items() if (layer [1] 'copper' or layer [2] 'soldermask') and data [3] True}

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

💡 Hint

Common Mistakes

Using incorrect operators like != or is for string comparison.

Mixing logical operators without parentheses causing wrong filtering.

The code checks if the layer name equals 'copper' or 'soldermask' and that the data is True (exists). Using == is the correct equality operator in this context.
