Did you ever have to find a power short circuit on a board with dozens, if not hundreds of little power decoupling caps all over the place? And they all look fine! How do you find the culprit? Wherever you measure across power, it's a dead short.
Or is it?
Not if you use a milliohm meter. Copper traces are very low resistance, but it's measurable with a milliohm meter. As you probe across power and get closer to the actual short, you'll measure less and less milliohms.
