As someone who makes his living selling circuit boards, I don't
understand this purchase.  I mean, I'm all for the "let's do it all
ourselves thing", but BGA placement equipment seems a bit over the top. 
Many of the chips this will be used to place will cost hundreds, if not
thousands, of dollars.  Isn't it wise to pay someone else to do the
placement, someone who does it all day long and knows how to do it?

Besides, I wouldn't send out a single BGA-containing board to my
TERRESTRIAL customers without having it X-Ray scanned first to check the
connections.  I certainly wouldn't send one into space without a scan. 
Are you planning on purchasing an XRay machine as well?
