Generating Gerber file
- Open your PCB design files on Altium designer software.
Select File -> Fabrication Outputs -> Gerber Files.
- General Setting
In the General Setting set the precision to 2:5 (0.01 mill resolution).
- Layers Setting
Please ensure you have the clear outline in mechanical layer.
If your boards are 2-layer, there will be no inner layer (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.
- Aperture Setting
Be sure to mark “Embedded apertures (RS274X).”
- Advanced Setting
When you ensure all configurations are fine, please click OK to generate the Gerber files.
Generating NC Drill File
- Generate the Drilling layer in Excellon format.
File -> Fabrication Outputs -> NC Drill Files
- We recommend you to choose the same units and format parameters as Gerber. Then click OK.
Then you get all files. Please put them into a single zip/RAR file.
