1. Access the PCB Layout: First, ensure you're in the PCB layout view of your project. In Flux, designs typically start in the schematic view and then transition to the PCB layout after the schematic is complete.
2. Select the Silkscreen Layer: PCBs have multiple layers, including the top and bottom layers, copper layers, mask layers, and the silkscreen layer. For adding text, you'll need to select either the top silkscreen layer or the bottom silkscreen layer, depending on where you want the text to appear on your PCB.
3. Choose the Text Tool: Look for a text tool or label tool in the toolbox. This tool allows you to place text on the PCB layout.
4. Add Text: Click on the location where you want to add text, then type the text you wish to appear on the silkscreen. This could be component labels (e.g., "R1" for resistor 1), identifiers (e.g., "U1" for the first integrated circuit), or any other useful information such as "Input" or "Output."
5. Adjust Properties: After typing your text, you can usually adjust properties such as font size, line width, and rotation to ensure the text is clear and fits well within the space allotted.
6. Placement Verification: Ensure that the silkscreen text does not overlap with pads, vias, or other components where it could cause manufacturing issues or be obscured. Also, check that text intended to help with component placement does not fall under large components, as this would make the text invisible in the final assembly.
7. Final Review: After placing and adjusting your text, review the entire PCB layout to ensure everything is labeled correctly and clearly legible. Consider the manufacturing and assembly processes where the silkscreen information will be instrumental.
8. Save and Export: Save your updated PCB layout. When you're ready to manufacture your PCB, ensure the silkscreen layer is included in the files you export for manufacturing.
