I am not expert on using the soldering iron and I am afraid I may
damage the circuit.

That's a legitimate fear - it's very easy to damage a PCB if you're
inexperienced. My advice is to practice. If you can spare the
time/cash, go to a hobby electronics shop (Tandy/Radioshack, etc) &
buy a tiny piece of strip board or other prototyping PCB & practice
soldering small pieces of wire to the strips.


Got any dead electronics? Practice on those. My advice is to try one of
the tasks I found hard: desoldering with a solder sucker bulb (Radio
shack, ~$5 US). If the joint isn't hot enough you won't get all the
solder. Too hot and you'll melt the board.

One more tip: Keep the tip clean. You can use a damp sponge or folded
paper towel to wipe off any collected gunk without unplugging the iron.
