Ordering PCBs from fabricators in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the number of PCB layers in the order.

PCB Design

💡 Hint

Common Mistakes

Choosing too many layers for a simple PCB increases cost unnecessarily.

Leaving the layers field empty causes order errors.

The standard number of layers for a simple PCB order is 2 layers.

medium

Complete the code to set the PCB thickness to the common standard.

PCB Design

order.thickness = '[1]'

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

A2.0mm

B1.0mm

C1.6mm

D0.8mm

💡 Hint

Common Mistakes

Using a thickness that is too thin can cause mechanical issues.

Choosing a non-standard thickness may increase cost.

1.6mm is the most common PCB thickness used by fabricators.

Fix the error in the code to correctly set the solder mask color.

PCB Design

order.solder_mask = '[1]'

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

💡 Hint

Common Mistakes

Using unsupported colors may delay fabrication.

Leaving the solder mask color blank causes errors.

Green is the default and most common solder mask color for PCBs.

4fill in blank

hard

Fill both blanks to set the PCB finish type and copper weight.

PCB Design

order.finish = '[1]'
order.copper_weight = '[2]'

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

💡 Hint

Common Mistakes

Choosing HASL finish when ENIG is required for fine pitch components.

Using 2oz copper weight unnecessarily increases cost.

ENIG finish is common for high-quality PCBs and 1oz copper weight is standard.

5fill in blank

hard

Fill all three blanks to set the PCB panelization, minimum drill size, and test method.

PCB Design

order.panelization = '[1]'
order.min_drill = '[2]'
order.test_method = '[3]'

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

Dv-score

Attempts:

💡 Hint

Common Mistakes

Using v-score panelization when array is required.

Specifying drill sizes smaller than fabricator capabilities.

Choosing test methods not supported by the fabricator.

Array panelization is common, 0.2mm is a typical minimum drill size, and flying probe test is standard for prototypes.
