80% of PCB fabs use Genesis 2000, it only support IPC 356. So those PCB fabs will refuse to accept IPC 356A nad IPC 356B
I use IPC-D-356 in CAM350 as gerber validation process for every PCB.
CAM350 doesn't support IPC-D-356B
Sorry for resurrecting an old post....
Any Idea how to export panel netlist in IPC-D-356
