But, if the solder balls bridge together or fail to connect, you have to take the part off and send it out for a $50 reballing procedure. I checked at Digi-Key, the OMAP3530 processor chip, alone goes for $84. Put the two memory chips on top of it, add all the other stuff, and no way could I make a Beagle for under $200. Obviously, other people can get the OMAP for a lot less than I can.
Also, inspecting the BGAs is done with an X-ray inspection system. Another "cant do that at home" process.
