Hi everyone,
I already order 3 times from BatchPCB with no problem but now I have some problem with my last design. I think the drc bot hate me, I submit my design a dozen of time but it always send me the first image I joint when is supose to look like the second one.
I already contact batchpcb but they are very not helpful, they said they will pass the design manualy bot I get no confirmation or anything…
What should I do, sorry for my bad english
Currently nothing is wrong with your design. Once a design is passed a confirmation email is sent to you immediately. Maybe something got lost in a email filter? As the one who passes all designs I can assure this is the standard procedure. If you have any further questions feel free to email me at support@batchpcb.com
I am not sure what you are saying. I think you may be saying that the Amplifier.gbl.png image is what you expected the bottom copper to look like,safarir:

and that the Botttom.png file is what you received back in the confirmation.
I don’t know that you are saying that the DRC bot failed your design, but that you are concerned that the image you got back is missing most of the traces.
I would try gerbv viewer to see if it shows your gerber files and holes the way you expect. That will serve as an independent view.
Maybe I did not understand correctly. SFEBPCB gives very knowledgeable information.
Just to clarify on whats happening here; the SFE DRC bot does not handle “negative draws”.
Gerber files can be made up of multiple layers with different draw polarities. In your image, the ground plane is likely drawn as a solid polygon, then “slots” are cut in it with negative draws into which the traces are drawn. This makes your gerber files shorter. The way the SFE DRC bot internally represents the Gerber data made it impossible to handle negative draws, and at the time the bot was written, no CAD package that saw significant submissions to BatchPCB used them.
So, to recap, your gerbers are probably fine, and will be produced fine. The DRC bot just doesn’t see them right.
