Single-layer vs multi-layer PCB in PCB Design - Interactive Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a single-layer PCB characteristic.

PCB Design

pcb_type = "[1]"  # Defines a PCB with only one conductive layer

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

Cdouble-layer

💡 Hint

Common Mistakes

Confusing single-layer with multi-layer or double-layer.

A single-layer PCB has only one conductive layer, so the correct term is single-layer.

2fill in blank

medium

Complete the code to calculate the number of layers in a multi-layer PCB.

PCB Design

total_layers = [1] + 2  # Number of internal layers plus two outer layers

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

Aouter_layers

Binternal_layers

💡 Hint

Common Mistakes

Using outer_layers instead of internal_layers.

Multi-layer PCBs have internal layers plus two outer layers. The variable internal_layers represents the count of inner layers.

3fill in blank

hard

Fix the error in the code that checks if a PCB is multi-layer.

PCB Design

if pcb_layers [1] 1:
    print("This is a multi-layer PCB")

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

B<=

C<

💡 Hint

Common Mistakes

Using equality or less than operators incorrectly.

A multi-layer PCB has more than one layer, so the condition should check if pcb_layers is greater than 1.

4fill in blank

hard

Fill both blanks to create a dictionary showing PCB types and their layer counts.

PCB Design

pcb_layers = {"single-layer": [1], "multi-layer": [2]

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

💡 Hint

Common Mistakes

Confusing the number of layers for single-layer and multi-layer.

A single-layer PCB has 1 layer, and a typical multi-layer PCB can have 4 layers or more.

5fill in blank

hard

Fill all three blanks to define a function that returns PCB type based on layer count.

PCB Design

def get_pcb_type(layers):
    if layers == [1]:
        return "[2]"
    else:
        return "[3]"

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

Cmulti-layer

💡 Hint

Common Mistakes

Mixing up the return values or the condition.

If the number of layers is 1, the PCB is single-layer; otherwise, it is multi-layer.
