Other details from the product page:

Gerber file requirement:

The following layers are needed:

  • Top layer: pcbname.GTL

  • Bottom layer: pcbname.GBL

  • Solder Stop Mask top: pcbname.GTS

  • Solder Stop Mask Bottom: pcbname.GBS

  • Silk Top: pcbname.GTO

  • Silk Bottom: pcbname.GBO

  • NC Drill: pcbname.TXT

Naming requirements:

  • "Mark your order number in silkscreen layer"

  • "Pack gerber files into a zip file named: D(your order number)_(Your PCB size) (e.g. D14756_10X10.rar)"

Comments from the forums (linked below):

KiCad is very easy...you can select the rules as follows:

    Click "Design Rules" -> "Design Rules".

In the window, type your rules, I usually use 8 mil (0.0080) for the tracks and the margin.

    Via Dia: 0.0295   
    Via Drill: 0.0197

You can use smaller sizes.

And:

Fusion requires min linewidth of 6mil and a min spacing of 6 mil. However, if you adhere to designrules that are stricter, for example, 8, 10, or even 12, then the chances of a bad board are much smaller.

Before submitting I will always run a DRC against 12mil design rules and wherever there is enough room, I'll fix the problems it points out to me. Next I'll run a 10mil design rule check. This should only fail around the 0.5mm pitch chips. And then I'll run the actual 6mil fusion DRC to make sure that I didn't accidentally miss a real problem.
