Hi All, One of my board having a short circuit (Zero Ohms) across a power supply (That supply connects to thousands of decoupling capacitors and 44 BGAs) and Ground. Is there any method to identify the route cause for the short without removing any components? Note: #### 1. The board is not yet powered on. 2. It was verified that the PCB doesn't contains any short across supplies before board assembly.
