Hi Technetters,

Do anyone have a quick answer about what is the maximum weight in term
of g/ball for BGA self center?  Which means that if the component is
over this limit it will not self center.  Also for double sized reflow,
what is the maximum g/ball that the BGA component will fall off?
Assuming 1.27 mm pitch and using 0.75 mm eutectic balls.

Thanks,
Alex
