Let’s try to replace with a new wireless charging IC and see how it works.

Attach the lower layer to the PCB holder and apply some paste flux to the wireless charging IC.

Heat with QUICK 990 AD Hot Air Gun at 360℃, air flow 3 for about 1 minute. Take down the wireless charging IC from the board with tweezers.

Continue to apply some medium-temp solder paste to the bonding pad. Heat with soldering iron at 365℃ to clean the bonding pad.
