I wanted to see where that story went, but I could not find the next report. Is there more to the story than just the one page link below?

Just now, I'm involved in a investigation of BGA interrupts. The BGA is LF and it's a LF soldering process. A few boards per one hundred show insufficient soldering or no wetting at all on some 5-10 positions (balls). Our vapour phase line is free from problems, even with superBGAs as big as 2,500 balls. The problems occur in the conduction oven line, and these are not superBGAs, but much smaller ones. I may add some results later.

It's nice to know we're not the only one with our balls on the line.
