Can someone explain how to test a PCB for short circuit?
Hello again ifixit,
Trying to begin repairing some water damaged/ no power phones here. iPhone 5/5c/5s. Can anyone point me in the right direction of diagnostics for a water damaged board? I'm really not sure how to find a short, or an open trace as I have no idea where on the board to measure voltages. Are there schematics out there that show all the correct voltages? I have not been able to find any.
I guess the first part I want to know is, should there be continuity between the battery terminals on an iPhone 5/5c/5s board? I've seen people talking about that as a way to find if you board is shorted, is there any value to this? I also read about hooking up an external power source(low voltage, high current) and then replacing whichever components start overheating.
I guess I just need to know where to go to start making sense of these units with no signs of life. Its a mess at the moment. Thanks in advance
Is dit een goede vraag?

What, really?! That would be awesome! I'm really looking for iPhone 5/5c/5s schematics. iPad 3/4 would also be very cool.
