Hello! Are there any tools/ softwares that can compare a board image against the gerbers and point out the differences. Eg: I want to compare the whole board image with a gerbers top layer and see the differences. Thanks!

Hi I think you already have the answer. It isn't the same as the true comparator of yesteryear, yet YES, some of the assembly machines have visualization post placement, compared to a golden board or dimensional images imported into the software.

Power up the circuit, and see how it performs. Check voltages at the input and the output, and compare to a known good board. Otherwise, you can check resistance in an un-powered circuit. Compare the readings to a known good board. cheers, ..rob
