Typical PCB fab defect.  Likely resist left on pad (chip or redeposit)
or it could be a scratch to the tin resist allowing the basis copper to
etch out.

Subject: [TN] Pad damage

Hi everyone,
 
Take a look at the link

<http://stevezeva.homestead.com/files/Pad_Damaged.jpg> 
 
Tell me what you think about the pad damage shown.  I have not come
across anything like this before, and was asked by our group leader if
this was acceptable.  My initial thought was this is not acceptable and
we should reject the board.  As always, I wanted to point out the IPC
section that would explain why this is not good.  However, I could not
come across anything except for section 10.2.9 (Laminate
conditions-conductors/lands).  I know there is probably a section I am
overlooking?  
 
There is still a high percentage of the pad intact and no evidence of
lifting.  Is this something common that others have seen?  If so, what
do I tell the board house to look out for to prevent something like this
in the future? 
 
Would anyone accept this?
 
 
 
Thanks,
