Diode Removal/Replacement

1.Remove defective diode by clipping its leads as close as possible to diode body.

2.Bend the two remaining leads perpendicularly to the circuit board.

3.Observing diode polarity, wrap each lead out of the new diode around the corresponding lead on the circuit board.

4.Securely crimp each connection and solder it.

5.Inspect the solder joints of the two “original” leads on the circuit board copper side. If they are not shiny, reheat them and apply additional solder if necessary.
