I've used METCAL for years for work such as you have. The base can be a bit expensive, but the number of different tips that they offer (from sold bars, to formed tips for specific component removal, etc..) is fantastic! www.metcal.com

Agree with Dan - we have had non-plated IC's that are a bit corroded come in and seen similar problems. Could it be that the tinning/plating process missed a corner somehow???

Optical microscope or SEM work fine. You say, "I have found out that the method of measuring intermetallic compound(IMC) formation is quite questionable." What's the issue?

Well that Genius did it on this BGA. It does have a heatsink and absorbs alot of heat. It just stinks because the BGA cost over 1000 and I really can not scrap a board. But that first profile does not look correct for this board with the BGA esp.

Thanks to all. I have it straightened out. We were running too hot and too fast and too long of a reflow time. I am running with Kic2000 and it works great. Thanks for all your input.
