Does anyone have any experiences with bga reballing. When I had reworked failed bga part with new part It was good. So I tried to reball bga detached but failed . I guess the cause of fail is thermal shock. IS IT OK TO REBALL BGA PARTS DETACHED ?

Are you running individual point soldering on each component lead, of are you drawing lines with the solder fountain to increase the speed of the process? Could be that if you are drawing lines, coupled with the very low flux levels you say you are

Having 10c thermal differential is a lot. Trying different paste might help - usually thermal expansion makes component detach from PCB, then joint is formed and solidified, then component goes back but is too late to form a joint. Cooling speed migh
