Use a solder sucker.. this is how they look like :
Solder sucker
The failure of soldering occurs often. In this case, the part or the wiring must be removed.
I will introduce the instruments that can be used for desoldering.
Solder pump
This is the tool that can be absorbed the melted solder with the repulsion power of the spring that was built in with the principle of the piston.
The usage is shown below.
Pushe down the knob of the upper part of the pump against to spring until it is locked.
Melt the solder of the part that wants to absorb solder with iron.
Apply the nozzle of the pump to the melted solder part.
Push the release knob of pump.
Then the plunger of the pump is pushed up with the power of spring and solder is absorbed inside the pump.
You need to do this operation quickly, otherwise the part gets damage by the heat. A little practice is needed.
Desoldering wire
This is made of thin copper net wire like a screen cable in a coaxial cable.
Like water inhales to cloth, the solder is absorbed to the net wire by a capillary tube phenomenon.
The usage is shown below.
Apply the desoldering wire to the part that wants to take solder.
Apply the soldering iron from the top and Melt the solder.
The melted solder is absorbed to desoldering wire with a capillary tube phenomenon. At this time you absorb solder while shifting desoldering wire.
When the solder can not be removed in the once, remove repeatedly while shifting the desoldering wire.
Hope this helps and don't forget to suck.... hehehe suck baby .. suck ..
