What a lot are forgetting to mention is the fact of using a non corrosive flux. Which you should find at any electronics store. The flux will allow for both sides of the solder to heat evenly allowing for quicker removal. If you are using that HAKKO set it around 690F. Apply a small amount ( a drop is good ) of flux to both top and bottom of the wire to be removed/replaced. Make sure to tin the wire you are putting back in. When you tin it make sure you only do the tip, solder will want to sneek up the insulation when you apply more heat to it. When all done make sure to clean the area up with a little isoprophyl alcohol. This will prevent any corrosion buildup.


Key thing when soldering is shiny solder is a good joint, dull is a dirty joint.
