cracks in the traces can make you pull your hair out..I use opti-visors and I always carry a 30X jewelers loop to help me look at PCB for cracks , bad solder connections and to read SMD components...another thing to watch for especially on the vertical I.C. is when the pads that the leads solder to, separate from the trace...in this case I use a razor blade to scrape open the trace right next to the pad, and then solder the exposed trace to the pad and lead, closing the crack that is where the trace meets the pad, it helps to apply some flux to the newly exposed trace to make the solder flow to it.....

I could relate to that. many times I faced this problem and I bought a big lens with light that comes with a stand. you could hock it up to the table and move it any where it is needed. also bought an hand held lens with light to help you see such problem. so far it is working fine. before i knew this, this kind of problems were giving me a lot of headache to figure out the problem.
