Default Help with testing a PCB boards

I'm new to these forums and I need help figuring out how to determine the source of a failure in a PCB board.

I just starting testing boards for my company and when I get a failure I don't know where to begin to find the source of the failure.

I have a meter needed to test the current but don't know how to use them.

Any direction will help, thanks

Is that what you were hired for?

You need an appropriate power supply to power the board and a circuit diagram to determine current flow and voltages. You can read a circuit diagram, right? As for your ammeter, check the maker's site for a manual. Otherwise, remember you check current in series and voltage in parallel.

Depends on the nature of the PCB - if there is firmware on a ROM or flash memory, an meter is no use to you - you need to examine the code on the chip.

@electrolytic - note you have dredged up a thread that has been dormant for more than 10 months. If you want to be of help, I would urge you stick with currently active threads, or start a new topic for a new discussion.
