We currently use solder paste when we do rework on PBGA's.

I m interested in knowing if it is required.  I heard that the paste was
not required for PBGA's, only for CBGA's.  Is that true ?  If so, do we
only have to put flux on the board to be rework before putting the new PBGA ?

Thank in advance.
