How Do I Create a PCB in SolidWorks?

Creating a printed circuit board (PCB) in SolidWorks is an essential skill for electronics designers. SolidWorks provides powerful tools to design and simulate PCBs, allowing you to bring your ideas to life. In this tutorial, we will walk through the step-by-step process of creating a PCB in SolidWorks, ensuring that you have a solid foundation to build upon.

Getting Started

Before diving into the PCB design process, it’s important to have a clear understanding of your project requirements. Determine the size and shape of your PCB, the number and type of components you will be using, as well as any specific design constraints.

Once you have your requirements defined, launch SolidWorks and create a new part document. This will serve as the base for your PCB design.

Creating the Board Outline

To start creating your PCB, you need to define its outline. This can be done using the sketching tools provided by SolidWorks.

  1. Create a new sketch: Click on “Sketch” in the toolbar and choose “Create Sketch”.
  2. Select a plane: Choose the plane on which you want to sketch your board outline. Typically, this would be the top or front plane.
  3. Draw the outline: Use lines and arcs to draw the desired shape of your PCB. You can also use constraints and dimensions to ensure accurate sizing.
  4. Exit sketch mode: Once you are satisfied with your board outline, exit sketch mode by clicking on “Exit Sketch” in the toolbar.

Your board outline is now defined in SolidWorks. You can modify it at any time by editing the sketch or applying additional features like fillets or chamfers.

Adding Components

With the board outline in place, it’s time to add components to your PCB. SolidWorks provides a vast library of electronic components that you can use, or you can import custom components.

  1. Access the Component Library: Click on “Library” in the toolbar and choose “Component Library”. This will open the component library window.
  2. Browse and select a component: Navigate through the categories and select the desired component for your PCB.
  3. Place the component: Click on the desired location on your board to place the component. Use constraints and dimensions to accurately position it.
  4. Repeat for other components: Continue adding components until all required elements are placed on your PCB.

You can easily move, rotate, or delete components as needed. SolidWorks also provides tools to check for any overlapping or conflicting placements, ensuring your design is error-free.

Routing Traces

Once all components are placed on your PCB, it’s time to connect them using traces. Traces are conductive paths that allow electrical signals to flow between different components. Select the plane where you want to create traces.

  • Draw traces: Use lines or arcs to draw traces between different component pins.

    You can use dimensions and constraints to ensure proper alignment and spacing.

  • Add vias: Vias are used to connect traces between different layers of the PCB. Place vias at appropriate locations to establish connections.
  • Exit sketch mode: Once you have completed routing traces, exit sketch mode by clicking on “Exit Sketch” in the toolbar.
  • With traces in place, you can use SolidWorks’ simulation tools to analyze signal integrity and ensure that your design meets all electrical requirements.

    Generating Manufacturing Files

    Once your PCB design is complete, it’s time to generate the necessary files for manufacturing. SolidWorks provides tools to create Gerber files, which are industry-standard files used by manufacturers to fabricate PCBs.

    1. Select Output Files: Click on “File” in the toolbar and choose “Save As”. Select “Gerber” as the file format.
    2. Configure Output Settings: Specify the required output settings such as layer selection, units, and other manufacturing parameters.
    3. Save Gerber Files: Choose a location to save your Gerber files and click on “Save”. This will generate all the necessary files for manufacturing.

    You can now send these Gerber files to a PCB manufacturer who will use them to fabricate your design. Ensure that you review the generated files thoroughly before proceeding with manufacturing.

    In Conclusion

    SolidWorks provides a comprehensive set of tools for designing PCBs. By following this step-by-step tutorial, you should now have a good understanding of how to create a PCB in SolidWorks.

    Remember to always consider your project requirements and utilize SolidWorks’ powerful features to optimize your design. With practice and experience, you’ll be able to create complex and functional PCBs using SolidWorks with ease!
