What would be the impact of using mini-stencil to paste the board for
BGA rework?

Would it increase the chance of bridging or minimize it through
increased clearance and solder volume?

Rgds,
Peter

With respect to PCB heating, some rework stations do a pretty good job
of
preheating the board when the profile is carefully planned and used.
With
that, the board most often is not subject to warpage as you speak.
