Dear Technetters,
        How do you handle rework of BGAs when there are BGAs on both sides
of the board and they are nearly directly on top of one another?
Similarly, how do you rework BGAs when the bottom side of the board is
loaded with passives and ICs inside of  the area outlined by the vias of the
topside BGA?  Our typical boards are 12 to 14 layers and are 0.062" thick.


Thanks in advance for your advice.

Wade Oberle
