We are entering arena of BGA-a new horizon in SM Technology as beginners
and are looking at IPC experts for valuable technical support.

Though we are well conversant with QFPs -upto 16 mils , BGA appears to
be a  different element and might need special factors.

What are things which beginner like me need to be careful to have good
initial yield.
What could be approach for low volume 50 mil pitch BGA.
Suggest Rework and placement equipment/tool and inspection methos/tools.
Is mechanical centering acceptable method for 50 mil pitch.BGA256.

I will appreciate all the support .
