Re: [Kicad-developers] New feature: support for Gerber job file.

I feel the via filling option in the job spec is too limited At my company we probably have a few hundred boards where we do via fills depending on their diameter. We keep their usage the same based on diameter, i.e. 8 mil vias go in pads, 6 mil vias are used in impedance controlled traces.And I kn

Re: [Kicad-developers] New feature: support for Gerber job file.

Yes this could be the case, and also for rigid-flex boards. I see from the spec that you already disclaim that the initial version of the job file will not work for these types of boards (Section 2, last few paragraphs) In the area I work, rigid-flex circuits are quite common (and I'm sure for al

Re: [Kicad-developers] New feature: support for Gerber job file.

Yes, a common stackup would be a two-layer rf substrate such as Teflon pressed onto a two-layer fr4 core with an fr4 prepreg in between. Galvanic processing is then done as usual. Best regards Simon Am 11. September 2017 19:07:19 MESZ schrieb jp charras : >Le 01/09/2017 à 12:38, Simon Küppers

Re: [Kicad-developers] New feature: support for Gerber job file.

Another element of this would be to support an arbitrary amount of stacked mechanical layers. I've been designing some flexible PCBs lately and using the user layers to specify stiffeners is a bit clunky. It would be nice if the 3d renderer could do multiple stacked edges. I've had to make separate

Nice. However the file format allows for only one substrate material being specified. In RF application it is often the case that two a RF ceramic substrate for example is bonded with fr4 prepregs and cores. Seems unnecessary limiting Am 1. September 2017 08:48:30 MESZ schrieb jp charras : >Le

Hi JP, Is this something new in GerberX2? I had never seen Gerber jobfiles before... I've given it a try (export and then load on GerbView) and seems to work OK, it loads every layer by just loading the jobfile. Any other gerber viewer which supports it to give it a try? gerbv

Hi JP, This is a nice feature and it seems to work well! I did have to make one change in gerber_jobfile_writer.cpp:154 to get it to compile on MacOS / LLVM: adding c_str() fputs( header[ii].c_str(), jobFile ); Best, Jon On Wed, Aug 30, 2017 at 11:26 AM, jp charras wrote: > Le 30/08/2017 à 13

[Kicad-developers] New feature: support for Gerber job file.

Hi all, I just committed a basic support for Gerber job file. The purpose of a Gerber job file is to handle info needed for board manufacturing. Because (unfortunately) Pcbnew has not actual support of the board layers stack, info about layer stack, dielectric and copper thickness, silkscreen
