Hi all,
 
will send pictures to Steve.
The two SEM images show SN100C boards that we got recently.
I don't like the look of the solder surface. Very grainy and
with lots of copper (darker spots). EDAX gives even fragments
of iron. My first thought was that the manufacturer had 
contaminated baths, which will be denied, of course. Anyway, 
my opinion is, that SN100C should be more like ordinary tin/lead, 
i.e nearly zero copper and a more shiny approach.
