Hello technet.

I have a question on PCB design. We are redesigning our board and a
question came up that I am unable to verify. We are looking at having a
plated through-hole near the end of the board. This plated through hole
will be used to place a post through and soldered into place for
electrical contact.  


The question that I have is as follows,
? Is there a requirement indicating that an annular ring is to be a
certain diameter larger than the actual through hole? And how far from
the edge of board should an annular ring be placed?

Thanks for your help.
