Hi folks! I know of two sources which have some photos:

1) ASW Soldering Handbook, 3rd Edition, author P. Vianco, ISBN
0-87171-618-6

2) Metallography of Tin and Tin alloys, International Tin Research
Institute, Publication 580

Neither reference has a large number of photomicrographs but there are
some. Good Luck.

Susan,

   I too have made this inquiry.   No responses yet.
   Do you have micro photos of 63/37 SnPb spheres and/or solder joints you
can share.

Victor,

We have good sources of photo micrographs of SnPb solder structure, but is
anyone aware of a source for photo micrographs of the new Pb free alloys?
