How to export CircuitMaker PCB to gerber files

Generating Gerber file

1. Click the “ Cerber” button

2. General Setting

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

3. Layers Setting

In general, there are minimum 8x layers you need to have a PCB fabricated, considering a standard 2 layer PCB. For multiple layers of PCB, these layers may be increased.
  • pcbname.GTL               Top Copper 
  • pcbname.GTS               Top Soldermask
  • pcbname.GTO               Top Silkscreen
  • pcbname.GBL                Bottom copper
  • pcbname.GBS                Bottom Soldermask:
  • pcbname.GBO                Bottom Silkscreen:
  • pcbname.TXT                 Drills
  • pcbname.GML/GKO        Board Outline
  • pcbname.GL2                   Inner Layer2( for ≥4 layer)
  • pcbname.GL3                   Inner Layer3( for ≥4 layer)

Please make sure you have the clear outline layer, outline layer or GKO layer can describe outline. Choose one of them to generate the outline.

4. Aperture Setting

Be sure to mark “ Embedded apertures (RS274X)

5. Advanced Setting

When you make sure all configurations are fine. Please click the OK to generate the gerber files.

Generating NC Drill File

1. Click the “ NC Drill Files” button

2. Please 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.

If everything looks OK, upload the zip file to JLCPCB order page.
