The materials needed for this are a soldering iron, soldering paste and desoldering wire, also known as a wick.
-
-
-
There are many types of soldering paste many of which are in a syringe like tube which makes it easy to get the paste in the exact spot it needs to be.
-
I personally use a plastic opening tool to scoop a little out and apply it gently on the spot I will be working on.

-
The location I will be de-soldering is right above the SPK location in the photo.
-
-
-
Place the de-soldering wick on the solder joint and put the tip of the soldering iron on it so the wick can heat up and absorb the old solder.

-
What’s left over is clean points on the solder board, ready for fresh solder.
