How to remove the chip power inductor?


We have already learned the simple judgment of the quality of the inductor. Since it can be judged, today I will explain how to remove the chip power inductor.


    Method 1: Use two chisel-shaped (flat shovel-shaped) or knife-edge soldering irons to heat both ends of the chip power inductor at the same time. After the tin is melted, the inductor can be removed by gently lifting it with a tweezers. It is necessary to pay attention to the temperature of the soldering iron and the strength of the hand.


    Method 2: Use a chisel-shaped (flat shovel-shaped) or knife-edge soldering iron to heat the two ends of the chip after each heating for 2 to 3 seconds, then move it back and forth at both ends of the inductor, while the hand holding the soldering iron is slightly pushed to the side, that is, The inductor can be removed.


    Method 3: Use a chisel-shaped (shovel-shaped) or knife-edge soldering iron to heat the side of the chip power inductor. At the same time, the hand holding the soldering iron can be pushed slightly to the side to remove the power inductor.


    Method 4: The hot air gun uses a small nozzle, the temperature is adjusted to 200 ° C ~ 300 ° C, the wind speed is adjusted to 1 ~ 2, when the temperature and wind speed is stable, one hand holds the components with tweezers, the other hand holds steady The hot air gun keeps the nozzle perpendicular to the power inductor to be removed, and the distance is 1cm~3cm. It is heated uniformly. After the solder around the inductor is melted, remove it with the tweezers in the direction of the vertical circuit board.
