Well there seems to be many questions and many answers and half answerers about
BGA, as I have said in my BGA workshops its surface mount all over again.
Some of the questions may be answered by the SMART Group Directory 1995/1996
which has a near complete copy of the SMART Group BGA Initial report which we
conducted for charity.
You can get a copy of the Directory from:
