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. 

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.

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.
