I noticed the big fat track too, but as it runs right through the ball next
door, and that ball is said to be OK, I took it that it had no effect on
our faulty friend. I asked Rudolph if he had any other microsection
pictures of the surrounding balls for comparison, in case this is another
example of BGA's 'shady tree' effect, as I call it, i.e. the balls sitting
under such a large parasol don't get the heat they need to reflow properly.

Good pictures Rudolph! Only thing I notice right away is that big fat trace
next to the ball that's failing...is the same pattern with this device on
the
other boards that you say uses this same asic?
