When you have finished your design in Eagle, the last step before sending it off to the fab house is to generate Gerber files. Autodesk EAGLE includes a handy computer-aided manufacturing (CAM) processor that allows you to load a CAM file and quickly generate the specific files you need for your design.
Generating Your Gerber Files (up to v.7, see at the bottom for v.8+)
- Open the CAM Processor
Open your PCB layout (.brd) file in Eagle, Click the “CAM” button or choose “File -> CAM Processor”. This will open the CAMProcessor tool that is used to generate the files.
- Select File-> Open -> Job
- Then navigate to your default EAGLE cam folder, choose the gerb274x.camfile, select Open.
- Adding a second silk screen (Optional)If you look at the tabs, you will see that you don’t have a file for silk screen bottom. For simple boards, the silk screen is usually on the top layer so that you don’t need the bottom. But if you need silk screen on bottom layer as well, follow these steps:Click “Add”Change Section to something like “Silk Screen SOL”Change File to “%N.pls”Deselect all layers
Select layers 20 “Dimension”, 22 “bPlace” and 26 “bNames”
- Select the Process Jobbutton to create all of your Gerber files. You can find all your generated Gerber files in the Autodesk EAGLE Control Panel in your project folder.
Generating Your Drill File
- Select the CAM Processor toolat the top of your interface or select File » CAM Processor to open the CAM processordialog.
- You now need to load a drill CAM job to get things started. Select File» Open » Job, and in your default EAGLE cam folder select the excellon.cam file, then select Open.
- You’ll have a single Generate drill data tab available that will grab the data from layers 44 Drillsand 45 Holes, just to name what you need. Select the Process Job button to generate this file.
- After you have created for each Gerber file, you should always look at them, using a Gerber viewer to ensure everything is ok.Check the below video to find out how to obtain all of your CAM and Manufacturing files for your PCB designs in Autodesk EAGLE.
