Hello,

I have a board before me with multiple BGA's on both sides. In some places
they oppose each other.
Does anyone have any manufacturing ideas for soldering the BGA's?
One I have heard is to mask the first side BGA's and heat through the mask,
BGA, board and finally the pads of the second BGA, finally removing the mask
when done. 

Thanks,
Rich
