Evamaria is correct. This does not meet the acceptance criteria of the PWB, which is listed in IPC 6012, amongst other documents. Etching flaws are described within that document. This is an etching flaw, where a scratch in the mask allowed the copper within the pad to be etched away during fabrication. -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Jones, Evamaria Sent: Tuesday, March 20, 2007 9:11 AM To: [log in to unmask] Subject: Re: [TN] Pad damage Does it meet the drawing?

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?
