I really don't have one, however our customers do. Since they see a spec in IPC for BGA's they have either addopted the 25% from the BGA spec or come up with their own. Also many have heard that IPC is working on defining critera. I was hoping othe

Depends on how much voiding you have as well. 25% is allowable.

How to Prevent Solder Joint Voiding and Cold Solder Defects during the SMT Reflow Process
Technical Library | 2013-12-11 23:24:32.0
Today's analyses of electronics reliability at the system level typically use a "black box approach", with relatively poor understanding of the behaviors and performances of such "black boxes" and how they physically and electrically interact (...) The incorporation of more rigorous and more informative approaches and techniques needs to better understand (...) Understanding the Physics of Failure (PoF) is imperative. It is a formalized and structured approach to Failure Analysis/Forensics Engineering that focuses on total learning and not only fixing a particular current problem (...) In this paper we will present an explanation of various physical models that could be deployed through this method, namely, wire bond failures; thermo-mechanical fatigue; and vibration.
