we have seen something similar,at the edge,sof the Bga the tracks were shorted with some burr and excess gold. It was very hard to find but it was root caused back to the BGA manufacturing process.

Hello. We have a low profile LCC on a board. The clearance is ~ 2mils after reflow. Cleaning away residual flux with an ultrasonic 50C water cleaner caused some LCC and 0201 components to loosen. Should we stay away from the ultrasonic cleaner?
