Technetters, A while back I remember seeing within I think an IPC document an approach for categorizing circuit boards in terms of component density, complexity, size, etc. so one board could be effectively compared against another board(s) as a means to judge say SMT processing differences. I thought that it was within J-STD-001 but did not see it. Would someone pls help and let me know what IPC doc has such information.
