Now I can point that people to this thread ;-) I the past year I have done a couple of boards commercially including an 8-layer iMX6/DDR3/FPGA board (all BGA). The experience has been mostly positive but I have had a few issues with the gerbers/xy: 1) There's a bug in the circle generation code that causes small unreported clearance violations, that my PCB maker kicked back to me. Reported here: https://bugs.launchpad.net/pcb/+bug/1100620 2) My PCB maker also moaned about below minimum feature widths in the polygons. I have manually edited my boards to get around this. I suspect they could have run a pass over it to fix it themselves, but whatever. 3) The XY file generation was entirely broken when it came to BGAs/PGAs. This has been fixed/committed now. They also had NO idea what to do with an ".xy" file, so I hacked up a script to turn it into the same format that Proteus outputs, which they happily accepted. 4) Have seen an issue where roughly half of a polygon isn't rendered. This one went away when I changed the circle division to 12 (from 40) in my local version. Probably a degenerate numerical issue. Will chase more when I have time. I too really appreciate the scriptability of geda/pcb. Though admittedly mostly I use that to get around the general clunkiness of the workflow and/or oddities (e.g. gschem's annoying insistence that you put a ":1" suffix on "net" labels) Lilith
