How to generate the Gerber files?
To place an order on JLCPCB, please provide us with the data files needed for production. These are:
Gerber files in RS-274x format for the copper layers, soldermask and legend layers, mechanical layer and SMD paste layers. Plus carbon, peel-off and via-fill layers as needed.
Excellon drill file(s) for drilling.
1. Gerber files and the Drill file must be stored in the same folder/archive.
2. The board outline must be provided.
For specific guides on how to generate the necessary files in the correct format, here is a list of some of the most popular circuit design programs we have notes for.
PCB Gerber File
If your Gerber filenames are good, this will save us a lot of time in checking your design.
There are many different PCB design software packages so there are many variations of Gerber filenames and filename extensions.
If you don't know how to map your files, don't worry about changing the file names and please contact our support for help.
We encourage you to use our free online Gerber viewer to check your Gerber files before placing an order.
