Today, FS Technology will explain to you the basic knowledge of circuit boards, from a simple introduction of circuit boards to complex design processes. Whether you're new to PCB design or want a refresher, FS Technology explains the process as simply as possible with this informative article.

A. What is a PCB?

PCB stands for Printed Circuit Board. If you are familiar with electronics, you know that these components are used for many purposes.

A PCB consists of a base material (copper strips), a substrate, and other components that are usually soldered to a circuit.

B. TYPES OF PCB

1. Point PCB
There's something on the back of a PCB like this. The holes at the top are for mounting components. Then connect wires to these components and solder them together.

Dot PCB design is difficult and often leads to many errors.

2.PCB layout
Layout PCB is much simpler. Layouts are created using PCB design software. The design is engraved on a copper board and the components are soldered to the board.

This approach minimizes errors and has a very short execution time.

C. Step-by-step guide to printing a PCB layout

Step 1: Design the Circuit

Run the program first.

Once the program loads, you should see your workspace at the top with all the tools and tools you can access by swiping down from the left. There is a white rectangle in the middle. The circuit will be designed inside this blue rectangle.

Step 2: Select Components

The components you use will depend on the type of circuit you are designing, so we won't discuss specific component selections right now.

However, there are two ingredients.

Go to "Libraries", then "Devices/Symbols". The selected component appears in a new window.
Use the toolbar on the left. Click on the component model and select it from the component library.
The component you selected appears in the device list. These devices can be rotated. There is a spin button to do this.

When you're ready, you can start adding components to the workspace. Once everyone is in place, the cursor can be used to draw connections between components to create circuits.

If you need to modify a component, you can right-click to see a drop-down menu with modification options.

After the virtual circuit is complete, save and debug the file.

Step 3: Design the PCB Layout - Open Areas

At this stage, virtual circuits are used to design the PCB layout.

You should see a window with a list of components.

To create slab edges, choose 2D Graphics Box Mode > Layers > Slab Edges.

You can now drag a box into the workspace. Click after the box is drawn and the line (green) turns red. The circuit is drawn within this yellow wireframe.

Step 4: PCB Layout - Design Components

Click on the components you want to use, and if you want to rotate them, use the rotate buttons and drag them to the workspace.

Once all components are in good condition, install them as needed. Use "Select Mode" to do this.

Once all the components are in place, wire them up. Use track mode to change track width. The width of the traces depends on the unique design of the PCB.

Click on the component end to connect the component. A green line will appear that you can drag to another component. When done, the green line will disappear.

PCB layer
it's a level
You'll see components on one side and connections on the other.

It's a double layer
The traces of the two components can also be seen on the sides.

There are multiple levels
Each layer is displayed in a different color: for example, bottom layer - blue, top layer - red, inner layer 1 - purple, etc.

Step 5: Design the PCB Layout - Trace

The white arrows indicate the direction of the component traces.
Green lines indicate coincidences
The blue line represents the trajectory
Red circles indicate tracking errors
Errors can be avoided by changing the trajectory.

If you have more than one layer on your PCB, you can use the left mouse button to change the traces between each layer. Double click this.

Note that you can use an automatic router. This allows you to set design rules and PCB widths before auto-routing.

After tracing is complete, save the PCB project to the same file that contains the Proteus virtual circuit. You can view 3D visualizations if needed.

Step 6: Print the layout

Go to "Output". Select the "Print" option.

You should see the Print Configuration window.
