How to export Gerber files from Altium PCB?

If you need to place a PCB order on the NextPCB website, you should provide a Gerber file which is for PCB manufacturing.

This article is teaching you how to export Gerber files from Altium PCB software.

Step 1.Open you.PCBDOC design files on Altium designer software

Click: File -> Fabrication Outputs -> Gerber Files.

Gerber Files

Step 2.General Setting

In the General Setting, please set the precision to 2:5 (0.01 mill resolution)

General Setting

Step 3.Layers Setting

Firstly, please make sure you have a clear outline in the mechanical layer.

If your board is 2-layer PCB, there will be no inner layers (G1, G2, G3....).

Include the layers that you want to export by marking these,

select “Used On” in Plot Layers, Select “All Off” in Mirror Layers.

Layers Setting

Step 4.Aperture Setting

Please make sure to mark the “Embedded apertures (RS-274-X)” format.

Aperture Setting

Step 5.Advanced Setting

See the below picture, when you make sure all configurations are fine. Please click the OK to generate the

Gerber files. Gerber Files will be automatically exported from the Altium cam viewer.

This tool allows you to verify that all layers have been generated correctly and that they are all in positive mode.

Advanced Setting

Step 6.Generating NC Drill Data

Don’t forget to export the NC Drill data after generating the Gerber file. Many engineers will forget this

step so that the supplier could not fabricate the PCBs without a drill data file.

a. Generate the Drilling layer in Excellon format.

Choose: File -> Fabrication Outputs -> NC Drill Files

NC Drill Files

b. We recommend you choose the same units and format parameters

in this setting process for drill data. Then click OK.

After this step, please zip the Gerber files and NC Drill data, then correct Gerber files have been done.
