Hi,
I had a PCB board with the following rules:
6 mil – minimum copper space
6 mil – minimum copper width
5 mil – minimum touching copper overlap
5 mil – minimum silk width
15mil – minimum drill diameter
5 mil – minimum annular ring
I forward this gerber file to OSH Park and Seeedstudio but did not pass the verification because they limits 6 mil
Please let me know if any company can make this board
Thanks,
MT
