I have been told in the past by PCB vendors that IPC controls the amount 
of plating one can expect in a double sided plated thru board which may 
contain both, holes with pads on both sides and some that have pads on 
one side only. Can anyone tell me what section of what spec I might find 
this in. I am writing a PCB general requirement standard for our company 
and we have this situation on alot of our older boards. We have stoped 
this practice and now place a min pad (.015 over hole dia) on the 
component side.

Thak you for any help.
