Traditional Gerber

About this tutorial

AISLER understands many Gerber file dialects. Please refer to Altium, Ultiboard, Labcenter Proteus and Designspark. This tutorial is a catch-all for all other PCB Design tools.


  • Make sure your drill files are exported in 2:4 precision and are set to the unit inches.
  • Please ensure that the board outline layer only contains the board outline

Keep in mind that Soldermask is an inverted mask. So you need to fill where you want to remove the mask.

Step 1: Please name your files like the following:

Layer Name in extension in Gerber
Top Layer project_name.toplayer.ger
Bottom Layer project_name.bottomlayer.ger
Top Soldermask project_name.topsoldermask.ger
Bottom Soldermask project_name.bottomsoldermask.ger
Top Silkscreen project_name.topsilkscreen.ger
Bottom Silkscreen project_name.bottomsilkscreen.ger
Top Paste (Stencil) project_name.toppaste.ger
Bottom Paste (Stencil) project_name.bottompaste.ger
Board Outline project_name.boardoutline.ger
PTH Drills (plated holes drills) project_name.drills_pth.xln
NPTH Holes (non-plated holes drills) project_name.holes_npth.xln
Internal plane 1 project_name.internalplane1.ger
Internal plane 2 project_name.internalplane2.ger

Please note:

In case your EDA-Tool exports multiple files of the same layer, you can also provide them in your zip. Please make sure, that the files have the identical name extension (e.g., *.drills_pth.xln) and we will merge them for you. The project name may differ between files.

Step 2: Zip it up

Step 3: Profit :wink:

Hallo ich habe Gerber Dateien von Easyeda und möchte diese gern fertigen lassen Wie muss ich diese umwandeln?

Hi @Borstel67, welcome to our community. So you would like to know how to manufacture EasyEDA via Gerber files. Please take a look at the instructions above.

die mir vorliegenden Gerber-Daten haben bei den Drills das Dateiformat
“” & “”
“xxx.drills_pt.xln” & “xxx.holes_npth.xln”

Funktioniert das auch oder muss ich hier etwas konvertieren?

Hi @Roman,

Welcome to the community!

The file name ending itself doesn’t define the file format. If your drill files have the correct format (excellon, 2:4 precision) there is no need to convert the files. In this case just change the ending from .nc to .xln and zip’ them up together with your gerber files.


When I uploadgerber files for internal planes in 4-layer designs, thermal reliefs and not showning correctly in the visualizer. The gerbers shown the thermal reliefs correctly in all the Gerber viewers I have.

Is this a problem with your visualizer software or is there some problem with uploaded plane layer Gerbers?
