1.Start a New Project in Altium Designer

Launch Altium Designer: Open the Altium Designer software on your computer.

Create a New Project: In the welcome screen or the main menu, select "File" > "New" > "Project". Alternatively, you can click the "New Project" icon on the toolbar.

Choose a Project Template: Altium Designer provides several project templates to help you get started. Select the one that best suits your needs, such as "Basic PCB Project" or "Schematic and PCB Project".

Name and Save the Project: In the "New Project" dialog, provide a name for your project and choose a location to save it. Then, click "OK" to create the new project.

Set Project Preferences: Altium Designer will open the new project. You can now set various project preferences, such as the default design rules, design layers, and output settings. You can access these settings by navigating to "Design" > "Project Preferences".

Create a Schematic: If your project includes a schematic, you can start by creating a new schematic document. Right-click on the "Schematic Documents" folder in the Projects panel and select "Add New To Project". This will open a new schematic sheet where you can start placing and connecting components.

Design the PCB: Once you have the schematic ready, you can create a new PCB document by right-clicking on the "PCB Documents" folder in the Projects panel and selecting "Add New To Project". This will open a new PCB editor where you can start placing components, routing traces, and designing the layout of your PCB.

Save and Manage the Project: As you work on your project, be sure to save your changes regularly. You can also use the Project panel to manage your project files, such as adding new documents, importing libraries, and organizing your design.

2. Place schematic parts

Now let's place our first component. Simply search for the component you want to add and you should see a list of all available options. Check the details and footprint of each one to make sure you select the right one.

Once you've found the component you want to use, add it to the circuit. To do this, right-click on the component and select "Place". Your cursor will change to indicate you are in placement mode. You can then click anywhere on the schematic to place the component.

1) . Open the saved schematic file you want to work on.

2) . On the left side of the screen, click on the "Libraries" bar. This will open the Libraries panel, where you'll see all the components available for your design.

3) . Select the components you want to use from the Libraries panel. Once a component is selected, click the "Place" button to add it to the white drawing area on the right side of the screen. You can then rotate or orient the component as needed for your design.

Click on the Tools bar, which will reveal a variety of tools you can use to modify your schematic. Take a look through the available tools and select the ones you need for your schematic design.

3. Update the PCB from the schematic

1).After making your modifications to the schematic, it's time to update the PCB document from the schematic. To do this, go to the Design menu and select "Update PCB Document".

When the Engineering Change Order dialog appears, click "Validate Changes" first. Once that's complete, click "Execute Changes".

When you see green checkmarks appear next to the "Check" and "Done" columns, it indicates there are no issues with your schematic design and the update to the PCB was successful.

4. Board Shape and Layer

Circuit board design should be completed within a specific boundary, so the board shape must be redefined. To do this, go to the Design menu and select "Board Shape" > "Redefine Board Shape".

PCBs typically have multiple layers. When designing a custom PCB, you'll need to define the specific layer for each component. To do this, go to the Design menu and select "Layer Stack Manager".

If a component is placed on the bottom layer of the PCB, double-click the component in the design to open its properties. Then, set the "Layer" property to the appropriate bottom layer. This will update the layer information shown in the PCB design graphic.

5. Rules and Routing

1.To define design rules, go to the Design menu and select "Rule...". This will allow you to choose the different types of rules you want to apply to your PCB design.

2.To automatically route the connections on your PCB, click the "Auto Route" button, then select "All...". This will initiate the auto-routing process.

3.While the auto-routing feature can be convenient, it may not always produce the best results. For more control over the routing, you can use the "Interactively Route Connections" tool. This will allow you to manually route the connections as desired.

6. Mounting Holes and File Generation

Locate the yellow hole indicator on the top of the PCB design.

Double-click on the yellow hole to open its properties. Here, you can customize the hole size, shape, net connection, and other relevant settings.

To add a text string to your PCB, go to the Place menu and select "String".

AD File Generation

1.Prepare the PCB Design:

Ensure your PCB design is fully complete and ready for manufacturing.

Verify that all components have been placed correctly.

Confirm that all necessary routing has been done.

Review the overall design to ensure it is ready for output and fabrication.

2.Navigate to the Output Job File:

In Altium Designer, locate the "PCB" panel.

Right-click on the PCB file you want to generate Gerber files for.

From the context menu, select "Output Job File".

3.Configure the Output Job File:

In the "Output Job" window, you will see a list of predefined output options.

Expand the "Fabrication" section.

Select the Gerber outputs you need, such as:

  • Top Layer
  • Bottom Layer
  • Solder Mask
  • Silkscreen

and any other necessary Gerber files for your PCB manufacturing.

4.Review and Customize Gerber Settings:

  • In the "Output Job" window, double-click on each Gerber output item in the list.
  • This will allow you to review and customize the settings for that specific Gerber file.
  • Verify that the layer name, file type, and any other relevant parameters are correct and match your PCB design requirements.

5.Set the Output Folder:

In the "Output Job" window, locate the section where you can specify the output folder.

Determine the appropriate location where you want the Gerber files to be generated.

Enter or browse to the desired output folder path.

Choosing the correct output folder is important, as this is typically the location where you will send the generated Gerber files to the PCB manufacturer for the fabrication process.

7.Generate the Gerber Files:

  • After reviewing and configuring all the necessary Gerber outputs in the "Output Job" window, locate the "Output Job" button at the bottom of the window.
  • Click the "Output Job" button to initiate the generation of the Gerber files.
  • Altium Designer will now generate the Gerber files and save them in the specified output folder.

8.Additional Files:

Depending on your preferences or the manufacturer's requirements, you may need to generate additional files alongside the Gerber files, such as:

  • Drill Drawing (NC Drill)
  • Drill Guide
  • Assembly Drawings
  • Bill of Materials (BOM)

These supplementary files can provide the manufacturer with further details and information required for the complete PCB manufacturing process.

Ensure that you review the manufacturer's requirements and generate any additional files that may be necessary for a successful PCB fabrication.
