It turns out that the PCB house will generate their flying probe e-test from your Gerbers, so a flaw in your Gerbers will be faithfully built and sent to you :-( --- End quote --- No, I don't have anything for drilling 0.4mm holes. It would also leave a some pads unconnected, unless I added some jumper wires... The thing is - had I actually sent Gerbers, this wouldn't have happened, since KiCad would re-pour the polygons before plotting. But no, I wanted the easy way and sent the PCB file to Aisler, which they happily processed, including the fault. |O |

I know this might be a bit off topic, but you can also try EasyEDA + JLCPCB. the software is made by them, so it's optimized with their manufacturing setup. the prices are ridiculously low as well so if there are faults, you won't lose much, mainly the shipping cost :-DD |

(I use Protel 99) But, what I do is generate the Gerber files, then READ them back in and view each layer. Hopefully, one would spot a missing pour or something that big while looking at the layers.

All design files are local and I can do my own publishing e.g. on Github. I chose Aisler for this little project because they're a European shop and that means less hassle with shipping and no taxes or customs duties. 3 boards 4 layer with ENIG finish were 28€ and shipping is free. The same PCBs on JLCPCB are 25€ but to have them delivered in a reasonable time frame I have to use DHL express shipping which adds another 16€. That puts me past the magical border above which I have to pay 19% import VAT on top. Also, DHL charges another, hefty fee for handlind taxes and duties. And if I don't let DHL do the handling, the PCBs will sit in a customs warehouse until authorities decide to contact me. Then I need to get the shipment released and DHL to do the final delivery. It's a big nuisance, not really worth it. |

Only send gerbers for fabrication, and always check the gerbers with multiple viewers. I use the oshpark and easyeda gerber viewers. |
