Adding a board outline to Gerber files in DesignSpark PCB, which is a software tool for designing PCB layouts, involves defining the shape of the PCB within the software. This is a critical step because the board outline determines the physical boundaries of the finished PCB. Here is a step-by-step guide for adding a board outline to Gerber plots:
-
Design the Board Outline:
- Open your PCB design in DesignSpark PCB.
- Switch to the "Board Outline" layer. In DesignSpark PCB, there's usually a dedicated layer where you can draw the outline.
- Use the drawing tools (e.g., lines, arcs) to draw the shape of your PCB. This shape defines the edge of the board, so ensure it is accurate and encompasses all the components and traces as required.
-
Verify the Board Outline:
- After drawing the outline, check that it is continuous without any breaks. A broken board outline can lead to manufacturing issues.
- Make sure that the outline is on its own separate layer and not merged with other design layers.
-
Generate Gerber Files:
- Once the board outline is verified, go to the manufacturing output options in DesignSpark PCB.
- Look for an option similar to "Output Manufacturing Plots" or "Export Gerber Files."
-
Include the Board Outline in Gerber Export:
- In the exporting dialog, make sure to select the board outline layer along with other necessary layers that you want to include in the Gerber files.
- If prompted, ensure that you are exporting all layers required by the manufacturer, including the board outline, copper (top and bottom), silkscreen, solder mask, and any internal layers.
-
Review and Validate the Gerber Files:
- After exporting, always review your Gerber files with a Gerber viewer. This step is essential to confirm that the board outline and all other data are correctly represented.
- Verify that the outline is present and all other elements are within the outline boundary as expected.
-
Send to the Manufacturer:
- Once you’ve validated the Gerber files, including the board outline, you can send them to the PCB manufacturer. Include a README or any additional notes specifying that the outline is included and should be used for cutting the PCBs.
Please be aware that the exact steps can vary based on the version of DesignSpark PCB that you are using. Always consult the specific help resources or manuals provided with your version of DesignSpark PCB for the most accurate instructions. If you’re unsure, you can usually find additional resources or contact support through the program’s official website or help forums.
