Joyce Koo Materials Researcher - Materials Interconnect Lab Research In Motion Limited Office: (519) 888-7465 79945 Mobile: (226) 220-4760 -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of vladimir Igoshev Sent: Friday, March 16, 2012 12:41 PM To: [log in to unmask] Subject: [TN] Champagne voids Technetters, I'm wondering is there a rule of thumb for pass/fail acceptance on champagne voids (like one for delta Tg or Au embrittlement)? We see a fair amount of micro (few microns level) voids on a customer board and they are wondering how they can "push" their IAg board supplier. X-ray rule isn't going to work as they can not be reliably resolve due to the size. Thank you very much in advance for constructive responses :-).
