1. From Prototype to Production with Eagle PCB Design
Workshop 6
Manufacturing File Generation
Layout of a single-channel CheerLights Wi-Fi controller

2. Manufacturing files are defined in layers – i.e.
Outline
Top Copper
Bottom Copper
Top Silkscreen
Etc.

3. Gerber and Drill Formats
The standard file types for PCB manufacturing are
Gerber RS-274X for PCB layers, and
Excellon for holes
Eagle creates Gerber and Excellon files directly using the CAM Processor

4. Eagle CAM files from manufacturers
Many PCB manufacturers create CAM files for Eagle that define the naming convention preferred by the manufacturer
For example, the Chinese manufacturer Seeed provides an Eagle cam file for two-layer PCBs called
Seeed_Gerber_Generater_2-layer.cam
We will now follow the steps to generate manufacturing files in Eagle using Seeed format as an example

5. Load the latest Eagle board and schematic
Download the latest files from Github as a zip: FiCheerLightsController
Open the board and schematic
Open the CAM processor in Eagle and load the file (job) called Seeed_Gerber_Generator_2- layer.cam
File>CAM Processor…>File>Open>Job><The Seed file>

6. Generate the Gerber and Drill files
Click Process Job
Eagle will generate the following files in your folder:

7. Upload the files to Seeed and view them
Zip the files in your folder
Visit Seeed at usion_pcb.html
Upload your zipped files
