I have a hard time believing that at 10kV
Werner,



 



I have a hard time believing that at 10kV acceleration potential that

they see only the SnNi IMC and very little of the SnPb solder behind the

IMC.

Hi George,

From my experience, what they seeing on the ball side is pretty much

SnNi IMC. What i find missing is any Au.
