Here I am going to show you how to clean up solder from two points on a logic board.In this case I am working on a chinese A13 all winner tablet and I am cleaning the solder points for the battery so I can correctly install a new battery on the logic boar
The materials needed for this are a solder gun, 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 solder gun on it so the wick can heat up and absorb the old solder.
Whats left over is clean points on the solder board ready for fresh solder.
