Figure A.6 Brass sponge.

Many tools are used to aid in soldering, but none are more important than a soldering
iron. Soldering irons come in a variety of types, ranging from basic soldering irons to
complex soldering stations, but they all serve the same function and purpose. Usually, a
good place to start is to buy a station that comprises a soldering iron with either a digital
or analog controller and a stand. These stations are becoming more common now and can

be inexpensive to purchase at your local store.

Over time your soldering tip will start to oxidize and will turn black; this is bad
because the soldering iron will not cling to the solder and you won’t be able to solder a
component; this is more commonly found with lead-free solder. This is where a simple

soft sponge comes to the rescue—every so often you should clean the tip by wiping all the
excess off. For even better results, you can use a brass wire sponge.

Apart from a soldering iron and solder, several other great accessories can aid in the
process of soldering. A solder wick is a vital tool for mopping up if you have made a bit of

a mess; you can also use it for desoldering. Solder wick is made up of thin copper
braiding, and just like any PCB, it will soak up the solder, erasing any excess drops.
