Hi,
We have a board with about 12,000 leads. The board is inspected to Class II standards.  We noticed about 300 leads were touched up.
 
I have not seen anything in IPC for % of leads that can be touched up on a printed circuit board before the board is considered unacceptable.  I don't know if this data is in IPC 7711 or 7721.  I have ordered the manuals though.
 
Is there a standard I should be looking for, or is there a % that people use?
 
Thanks,
Kerry
