If you create your PCB layout with the freely available program KiCad, please note the following instructions below.
The KiCad software is a complete project manager with a number of integrated modules, such as Schematic Editor, PCB Editor and Gerber Viewer.
KiCad is open source, and thus available free of charge
We naturally import your ODB++, Gerber-, KiCad-, OrCAD-, Target-, Eagle-, Altium-, IPC-2581-, DPF- and Sprint layout data free of charge!
Please send your data as .kicad_pcb or Gerber export (+drill file).
Before you send us your data, please run the KiCad Design Rule Check (DRC). This avoids queries, thus saving you valuable time and can lead to the detection of errors in the layout.
When using KiCad's DRC, please select the option: "Refill all zones before performing DRC".
If you send us .kicad_pcb data, we will take care of generating the production data (Gerber export) for you with our standard settings.
Following KiCad’s official recommendation, we create the Gerber data with "refilled zones" . We therefore recommend that you select the option "Refill all zones before performing DRC" for the KiCad DRC (see above).
If you export the Gerber data (+ drill file) yourself, we recommend that you check the generated production data with KiCad's integrated Gerber viewer in addition to the KiCad DRC (see above). This allows you to check, e.g., whether you have exported all the necessary layers.
Our experience with numerous KiCad data sets of different program versions / different users teaches us: It is more crucial to run the DRC of KiCad than the question in which file format you send us your layout.
The design rules can be found directly in the main menu of Pcbnew. There are two tabs:
For an optimal result, please define the free-of-charge high-tech parameters of Multi-CB:
This guarantees the best technology at the best price. The minimum possible values can be found here: Circuit board design parameters.

Additional required track-widths, clearances and Vias can also be defined in the Design Rules.
You can start the Gerber Export under File / Plot. In the Plotting dialog, you define the layers to be exported. Please activate the function "Subtract soldermask from silkscreen" to avoid silkscreen on the pads. You can usually use default settings for all other options.
After the Gerber export, you start the drill file export from the same window (Generate Drill File). You can usually use default settings for all other options.
By default, KiCad uses Protel's tried and tested filename extensions for Gerber export. Please use the default setting.

To view the generated Gerber files, click the Gerber Viewer icon in the KiCad Project Manager. Then import your Gerber and drill files:
You can now check your complete production data. Pack all into a zip file which you can upload with your PCB order.
