     Does anyone know if there is a visual-mechanical specification for the 
     PBGA by IPC, SEMI, EIA, JEDEC ??? If there is ... how can I get a copy 
     of it ?
     
     I am particularly interested to understand what is the acceptable 
     specifications for the substrate delamination/chip/finish at the edges 
     of the PBGA unit.
