What process steps have been completed before the cross-section? What type of devices have solder cracks? Are the cracks found after just normal processing or after some type of validation testing? It is very unlikely to be a heating/cooling issue

Maybe attaching some pictures of your cracked solder connections might help us in offering suggestions to help you with your problem

You might want to take a look at Allied High Tech. I was investigating this same thing a few years ago. I never purchased it, so I can't vouch for the product itself, but it's another option. http://www.alliedhightech.com/grinding/xsectiontool/

Can anyone recommend a good reasonably priced microscope for looking at cross sections? The ones I'm finding with the magnification we're looking for all seem to be for glass slides.
