Really nice photos of dendrites, beautiful fern-like structure.
 
Maybe one day we'll run into each and you can buy me that beer, but only
if I can buy you one too...
 
Steve

Subject: DENDRITE GROWTH



Steve, I was told you could post my pictures concerning the Dendrite
Growth inside of plastic ICs. I have enclosed the pictures two ways, in
the email body and on a .doc.  The information related to this I sent
out to the TechNet group this week. Thanks in advance I was told if I
see you to buy you a beer, Jon  

 

Enclosed is pictures  of the dendrites. 

 

Here is what the report stated associated with the pictures. 

 

EDX Spectra #1 is from the thick part of the dendrite on the bond pad
area, and shows a strong peak of silver (Ag) along with smaller peaks of
gold (Au), copper (Cu).   EDX Spectra #2 is the dendrite growth on the
Si surface; here the stronger peak is Ag with a trace of Cu.  The wire
ball is seen in EDX Spectra #3 and is primarily Au with smaller traces
of Ag.
