Export

Export Gerber files

Once you're satisfied with your board, all you need to do is export some files for the printing process.

Go to Files > Fabrication Outputs > Gerber Files In the setup, choose the following settings:

• Units: Millimeters
• Format: 4:4
• Layers: plot the following:
  • GTO (Top Overlay)
  • GBL (Bottom Layer)
  • GM1 (Mechanical 1) if you defined a contour for the board

You also need to export the holes. Go to Files > Fabrication Outputs > NC Drill Files and choose the same precision as for the Gerber file (millimeters and 4:4). The resulting file is a .txt in the project folder.

Stencil for acid etching

Acid etching needs a black an white stencil. You can generate one by simply printing your design in File > Print...

However, you first need to setup your page in File > Page Setup... First, change the scale mode to Scaled Print and a scale of 1.00. Also choose Mono as the colour set.

Then in the Advanced menu, keep only the layers you want to print. In general, it should be Bottom Layer and Keep-Out Layer. You thus need to select all the other ones and delete them.

Check Top, Bottom, Double Sided, Holes and Design Views. You do not need to mirror it.
