agree, it is part of design - max reflow on assembly plus max repair  
- those are the one consider worse case and units build up for the  
qualification test (if it is new platform, you might want to have no- 
repair as bench mark case to compare the reliability results, and  
assess if the repair is suitable or not for specific components and  
assembly... some times, throw away make much more sense... especially  
if the most expansive parts is designed as last on - to prevent  
excessive heat cycle).  IMHO.
