Hello, I want to do a project of iRobot Roomba 760 PCBA repair of dead left wheel, reflowing 2N7002 N-Channel MOSFET. My Irobot shows an error on the left wheel, but the wheel module works because I tested it on another I7, could you explain the full procedures to identify which mosfet is damaged and how to remove it from the board and install the new components reflux? thanks.

Roomba charging error 3 code appears. According to experience, it can be judged that the old battery has not been charged for a long time. The battery leaks and corrodes the main board circuit.
The most straightforward method is to first visually check whether the four electrodes of the battery have corroded black or abnormal corrosive substances, and then check whether there are white corrosive substances on the shrapnel in the battery compartment.
