Good morning, a question arose where I need some help. We have a PCB which mounts into a chassis then mates to another board in the same chassis via a right angle male header to a female connector. The issue is that the male connector does not protrude fully into the female connector. We know the issue is that the spacing between the two boards is incorrect, but we'd like to do a full dimensional tolerance analysis to determine the optimal spacing. One question that arose which I cannot answer and I'm hoping to get some assistance with, is related to the PCB artwork to PCB tooling hole registration/tolerance. I did a quick look through many of the IPC board specifications, but wasn't able to find anything. I'm thinking my searching skills are waning, so I'd like to get some help from this group. Thanks in advance.

Regards,
Steve Vargas
