Some of what we see in the scanning electron microscope can be difficult to explain, like this case of a MLCC termination that had some contamination on the surface.

The termination is tin plated. Contamination appeared to be carbon spheres that are perhaps electro-statically held in position. How might this happen is difficult to explain.
