TEKTRONIX DPO 6GHz scope issue - broken BGA ball connection?
morzh:
My hat's off to you for the effort and the success.
Very few people will go to this length in order to fix a device, even a very expensive one.
I once modded a board I designed (a first prototype) with a reasonably large BGA (AMD Geode CPU) on it; I needed to solder to a second row ball which had no drop via under it. I was able to heat a strand of wire, routed between the balls, to hot enough temp to start melting the ball and solder too it. (The alternative was spinning the board). It was like 18-19 years ago. But that does not even come close to what you've done.
You should be proud of yourself. It has been quite a feat.
Best
Mike.
