You may wish to compare notes with Ingemar Hernefjord, as he is having
problems with some type of whiskers growing from his balls also, and has
several interesting pictures posted. The thread is in last week's IPC
forum.

I have some older 90/10 Pb/Sn CBGA parts which show a considerable
amount of oxidation on the balls.  What's the best way to clean them
prior to reflowing them?
