Hi Inge,

I'm surprised that Dewey didn't pick up on you Freudian Slip. You wrote "has
anyone of you experience from 'Die & Pray' technology?"

Let's hope not ;-)

By the way, speaking SJ issues, has anyone of you experience from Die & Pray
technology, like the one described by some guys, who tested large game
boards, see figur 9 and 10, dye and pry testing? It's not easy to pry so
large BGAs. What kind of tools etc do you use? Myself, I had to dip the
board under test in LN2 before prying off the superBGA. That's not good, the
low temperature can mislead the result.
