Today, our case is about fixing an iPhone XR that has no signal and motherboard electricity leakage. When we inserted the SIM card and tested, the ICCID and IMEI number could be checked. Our initial judgment was that the problem was probably related to the signal power amplifier circuit. We continued to check the circuit and we found that the power amplifier IC had burnt out. Next, we connected the burnt bonding pads by jumping wires and replaced with a new power amplifier IC.
