Step1: The work before generate the Gerber file
Before generate Gerber file, you need to set criteria, but for most of PCB designers, these are not necessarily. The following is a brief explanation of these settings, You can also ignore these setting when generate Gerber file.
1. The settings of PCB shape and size, generally are mechanic1,2 layers.
2. Before generate the Gerber file, the preprocessed of PCB file.
The preprocessed include:
a. Add break away rails of PCB
b. Add stamp hole.
c. Add the machine jack.
d. Add mouting hole
e. Add drilling description.
f. Add dimension description.
g. Set the origin
Step2: Generate Gerber file
1. Open the Gerber Files.
File -> Fabrication Outputs -> GerberFiles.
2. Parameter setting.
a. “General” setting
Set Units to “Inches”
And Format to “2:5”
b “Layers” setting
Select “Used On” in Plot Layers
Select “All Off” in Mirror Layers
Check “include unconnected mid-layer pads”
Uncheck all in Mechanical Layers to Add to All plot
c. “Drill Drawing” setting
Uncheck all boxes.
Select “Graphic Symbols” in Drill Drawing Symbols
d. “Apertures” setting
Select RS274X
e. “Advanced” setting
Select “Separate file per layer” for Batch Mode
Select “Suppress leading zeroes” in Leading/Trailing Zeroes
Select “Reference to relative origin” in Position on Film
Select “Unsorted” in Plotter Type
Click “OK”
Gerber Files are automatically loaded in 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.
3. Generating NC Drill File
a.In the PCB view, and select : File / Fabrication Outputs / NC Drill Files
Select “Inches” in Units
Select “2:5” in Format
Select “Suppress leading zeroes” in Leading/Trailing Zeros
Select “Reference to relative origin” in Coordinate Positions
Click “OK”
b. Import Drill Data : Click “OK”
c.Import Mill/Route Data : Click “OK”
4. Package Gerber File
Compress all the files in a single .zip file.All Gerber and NC Drill files generated by Altium Designer are automatically saved in the Project output folder.
