Manual trace routing in PCB Design - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start a manual trace from the selected pad.

PCB Design

start_trace = pcb_board.[1](selected_pad)

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

Astart_trace

Binit_trace

Cbegin_trace

Dtrace_start

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'begin_trace' or 'init_trace' which are not valid methods.

The method start_trace is used to begin manual routing from a pad.

2fill in blank

medium

Complete the code to add a corner point at the current cursor position during manual routing.

PCB Design

trace.[1](cursor_position)

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

Aplace_corner

Binsert_corner

Cadd_corner

Dcorner_add

Attempts:

💡 Hint

Common Mistakes

Using 'insert_corner' or 'place_corner' which are not recognized methods.

The method add_corner adds a corner point to the trace at the cursor position.

3fill in blank

hard

Fix the error in the code to complete the manual trace routing by connecting to the target pad.

PCB Design

trace.[1](target_pad)

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

Aend_trace

Bcomplete_trace

Cfinish_trace

Dclose_trace

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'finish_trace' or 'complete_trace' which are not valid methods.

The correct method to end a manual trace is end_trace, which connects the trace to the target pad.

4fill in blank

hard

Fill both blanks to set the trace width and layer before starting manual routing.

PCB Design

trace.set_[1](0.25)
trace.set_[2]('TopLayer')

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

Awidth

Bheight

Clayer

Ddepth

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing width with height or depth, and layer with depth.

Use width to set the trace thickness and layer to specify the PCB layer.

5fill in blank

hard

Fill all three blanks to create a manual trace dictionary with start point, end point, and trace type.

PCB Design

manual_trace = {
  'start': [1],
  'end': [2],
  'type': [3]
}

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

Astart_pad

Bend_pad

C'signal'

D'power'

Attempts:

3 left

💡 Hint

Common Mistakes

Using incorrect variable names or trace types.

The dictionary keys require the start pad, end pad, and the trace type as 'signal'.
