Exporting CAM Files for PCB Manufacturing: A Step-by-Step Guide

After completing the layout, it's essential to export CAM files for PCB manufacturing. This guide walks you through the steps required. Start by clicking "File" in the layout menu and choosing "CAM." You have the option to import existing CAM settings or add layers manually. Typically, you'll generate N+5 CAM files, where N is the number of design layers plus additional files for silkscreen and solder mask. Fill in the necessary details for each layer, select desired features, and run the process. Finally, your CAM files will be ready for submission to the manufacturer.

  3. Overview After Layout is done, we need to export CAM files of the PCB. CAM files have the information of the board for manufacture.

  4. Step 1 • In Layout, click on File - CAM

  5. Step 2 • Here you have 2 options: • Click on “Import” to read CAM export settings from other designs • Click on “Add” to generate CAM of each layers by yourself • Typically, the total number of CAM files is N+5. N is the number of the PCB design layers. 5 includes 2 Silkscreen, 2 Solder mask, and NC drill.

  6. Step 3 • To add new layers, • Fill in the name of CAM file you want to generate in “Document Name” and “Output File” • Select what type of layer it is in “Document Type”. Typically select Routing/Split Plane, Silkscreen, or NC drill. • Choose the location of the layer (Top/Bottom/Inner) in “Fabrication Layer” • Click on “Layers”

  7. Step 3 • Select what features you want to add to the layer. • Notice that for Silkscreen layer, both the Silkscreen layer and the attached layer (Top/Bottom should be selected)

  8. Step 4 • After adding all the N+5 layers, select all the layers and click run. Your CAM then is ready in the PADS_project – CAM folder. • Optionally, you can export your CAM file settings by click on “Export”. • The N+5 files are the files you need to send to the manufacturer.

  9. You’re done!
