Hi, There is a $69 tool I wrote. Go up to www.partsync.com and download BOM Builder. It has a 30 day free trial. The checking is more visual but automatic checks can be done. The main issue is having "Package Models" and PCB locations / rotations. The "Package Data" is in a state of change right now, I am adding data to support 3D part generation. One item I have done in the past is what I call "Pin In Paste". I took the metal definitions for packages and verified that the metal areas overlay the solder paste openings by at least 95%. Yep, some board fail. Look at www.kondner.com/files/BB10B_SMT.pdf for a sample with RED pins in light blue paste. Don't forget to read the manual! :-) You mention a number of hard to believe items. Yep, absolutely true. I personally processed a lot of job when starting up a proto assembly company, they are all true. Bob K.
