Since there are too many related components on the circuit, we use rosin detecting to find the short-circuited component. The Rosin Dispenser is used to dispense rosin this time. Compared to the traditional soldering iron, the operation is easier with better effect.

Then we apply a voltage of 3 V to the motherboard. It can be seen under the microscope that rosin on a capacitor has melted. We can judge that the capacitor is damaged.

The next thing we need to do is to remove the capacitor. Remove the capacitor with Hot Air Gun at 340 °C and airflow 3. Please protect the surrounding battery while heating to avoid damage.
