because it is in the drill data and saves work
yeah yeah i know but it has always worked in USA :)
i do think that if we had had 2 drill files as i have heard discussed that too would have solved this issue

Dennis, I don't recall from previous years conversations, do you do fab formal drawings? I have dealt with Asia a fair amount during my career and have never had a similar problem. However I do formal fab drawings on anything that is not purely prototype. These may not be fully 100% what IPC asks for in a fab drawing but it covers all the required details. In my drill charts I make it adequately clear which symbols are NPTHs. I do not even allow the simple "Y" or "N", I change it to a full Yes or NO in the Plated column. Let alone previously with Pads the PTH indication was simply " " or "*". What does * mean? The other detail I put in the drill chart with Protel outputs is the tool number from the actual drill file. Then there is absolutely no excuse for missing the NPTHs in the drill file.

anyone else have issues with asian bd houses not spotting the NTPs ?
i use a few shops and have never had trouble, but now with a new one the holes came plated (no pads), wasn't a big deal in this case
i heard some noises about this on the DXP list to the effect that some shops expect a separate drill file for the NTPs
i sent the DRR but i guess they didn't read it or understand it
one time on a different job they held a job because i had a trace too close to a pad (at least as observed looking at a single layer)
i explained that it was fine because they were all on the same net (joined on a different layer)
they couldn't understand what i was saying
after a series of emails the last one from them was
PLEASE ANSWER - RESEND - RESEND ENGINEERING WANT TO KNOW OPEN OR SHORT OPEN OR SHORT ????
i replied simply SHORT
and all was well
