Werner,

Thankfully, I don't have any pictures of that problem, but I may take some scrap/obsoleted/ or otherwise trash parts and soak them to produce some pictures. But in the mean time, here's a pretty good link that does have some SEM images of "Pop-corning"...good technical paper too.

Hi 'Netters,
Could any of share some good pictures of a 'popcorned' component and a
component with delaminated die. I would of course give full credit as to
source.

Thanks,
Werner Engelmaier
