You've just been given a board with a shorted BGA site. You've done this many times before, but still, as any one who has attempted BGA removal and replacement knows, BGA rework at any level can be finicky and challenging.
In this case the challenge is magnified as this BGA component has 2600 balls at 1.0 mm pitch. You're no quitter so you plow ahead. Removal of the component is delicate but routine for an experienced pro. You get that done with a little cautious foresight and ...

We've all heard of via in pad, blind vias, even buried vias, but have you ever experienced the "Via to nowhere" phenomena? Well, here's how it goes.
We received a call from a customer that found they were missing ten vias on their now populated circuit boards. The vias were supposed to connect from surface circuitry and to an internal ground layer ...
