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.

Note:
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.

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.
