Convert PCB PDF to Gerber File PCB service bureau: PCB (printed circuit board) to Gerber data conversion, dxf to gerber, PDF to Gerber, Adobe PDF to Gerber, PDF Print to Gerber, PDF Drawing to Gerber, PDF Gerber Conversion, and PCB PDF to Gerber 274x data page. In our example, we’re going to load up the Gerber RS-274X CAM file. This will provide us with five individual Gerber files for the LED Flasher project we completed in our PCB Layout Basics Series Part 1, Part 2, and Part 3. Here’s how to do this: Open your PCB layout (.brd) file in. Altium Designer's PCB Editor, for example, differentiates between Gerber layers by their extensions, such as.gtl for the top layer and.gbl for the bottom. Other design programs might export a.top file for a top layer, and a.sol file for the bottom (solder) layer. The software will generate your Gerber files in the same directory as your design file and in a folder called artwork, and display a log file. But we’re not done yet. But we’re not done yet. We still need to generate the NC Drill file in Excellon format to indicate where all the drill holes on the PCB need to be and of what size.
Open the CAM Processor. In Eagle, open Board view. Click the “CAM” button or choose “File-CAM.
In this Gerber tutorial, I will teach you how to create the files you need for a 2-layer board using Cadsoft Eagle. After you have completed this tutorial you will have all the necessary files needed to send to most PCB manufacturers.
This tutorial is out of date. I have switched to KiCad, so I recommend the updated tutorial How to Create Gerber Files in KiCad.
Step 1: Open the CAM Processor
In Eagle, open Board view. Click the “CAM” button or choose “File->CAM Processor”. This will open the CAM Processor tool that is used to generate the files.
Here you can define the sections you want to create files for.
But you don’t really need to understand this. Actually I have never really thought about the details of this until I was writing this article. I have just been using ready-made configurations. And that is probably what you want to do as well.
Step 2: Open a predefined job
To simplify creating Gerber files, Eagle comes with a predefined job for this. It is called gerb274x.cam.
(Note: If you want to order PCBs from Seeed Studio’s Fusion PCB service, you should instead download their own CAM-file from the bottom of their submission guidelines page. Be aware that this will give you different file names than the ones listed below in this article.)
To open it in the CAM Processor click “File->Open->Job…”
Browse to your …/eagle/cam/ folder, and you should see a file called gerb274x.cam. Choose it and click “Open”.

You will now see five tabs in the CAM Processor. Each of these tabs will generate a Gerber file.
Step 3: 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. Some of the cheap circuit board manufacturers don’t even allow bottom silk screen.
But if you need silk screen on bottom layer as well, follow these steps:
How To Convert Gerber File To Pcb Files
- 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”

There you go.
Step 4: Create each gerber file
Select where you want to put the Gerber files by clicking on the “File” button and choosing a folder. Do this for all the tabs.
Then click “Process Job”. This creates your Gerber files.
Step 5: Adding file for drill holes
Even though drilling is supported by the Gerber format, manufacturers usually want the Excellon file format for specifying drill holes. Luckily, Eagle also comes with a predefined job for creating a drill file.
(Note: This step is automatically done if you’re using the CAM-file from Seeed Studio that I linked to in step 2.)
Open it in the CAM Processor by clicking “File->Open->Job…”
Browse to your …/eagle/cam/ folder, and open the file named “excellon.cam”.
Select where to put the output file by clicking on the “File” button.
Then click “Process Job” to create your Excellon file.
Step 6: Check output files
You should now have the following files:
- *.cmp (Copper, component side)
- *.drd (Drill file)
- *.dri (Drill Station Info File) – Usually not needed
- *.gpi (Photoplotter Info File) – Usually not needed
- *.plc (Silk screen, component side)
- *.pls (Silk screen, solder side)
- *.sol (Copper, solder side)
- *.stc (Solder stop mask, component side)
- *.sts (Solder stop mask, solder side)
After you have created each gerber file, you should always look at them using a Gerber viewer to make sure everything is ok.
Summary
This Gerber tutorial shows one way of creating the files you need. Even though this should be OK for many PCB manufacturers, you might find that some would want the files created in a slightly different way. If so, don’t worry, they will probably provide you with a Job file you can load directly into Eagle or at least have a good explanation on how to do it on their website.
