Hello All,
I am working on a board which is having 3.3V short to ground and the impedance between them is 5 ohms. Since this 3.3V is going to many places, removing components one by one is time consuming.My colleague told me an idea that give 100mv @ 0.5A on the 3.3V path and look where the voltage is low to find the short. I have done the above method but the voltage is 70mV everywhere on the 3.3V path. Plus, I don't understand the logic of the above method that different voltage drop on the same path. Please let me know if the above method makes sense to anyone.
Also, if there is any other ways that I can try, please suggest.
Thanks and Regards,
Muthu
