Besides a soldering iron and solder, there are a few additional things you’ll need to have on hand for successful soldering. To wit:

 Third-hand tool or vise: It takes at least three hands to solder: one to hold the items you’re soldering, one to hold the soldering iron, and one to hold the solder. Unless you actually have three hands, you need to use a third-hand tool, a vise, or some other resourceful device to hold the items you’re soldering so you can wield the soldering iron and the solder. (See Chapter 3 of this minibook for photographs of a third-hand tool and a hobby vise.)

 A sponge: Used to clean the tip of the soldering iron.

 Alligator clips: They serve two purposes when soldering. First, you can use an alligator clip as a clamp to hold a component in place while you solder it and, second, as a heat sink to avoid damaging a sensitive component when soldering the component’s leads. (A heat sink is simply a piece of metal attached to a heat-sensitive component that helps dissipate heat conducted by the component.)

  Eye protection: Always wear eye protection when soldering. Sometimes hot solder pops and flies through the air. Your eye and melted solder aren’t a good mix.

 Magnifying glass: Soldering is much easier if you do it through a magnifying glass so that you can get a better look at your work. You can use a tabletop magnifying glass, or a magnifying glass attached to a third-hand tool, or special magnifying goggles.

 Desoldering braid and desoldering bulb: These tools are used to undo soldered joints when necessary to correct mistakes. For more information, see the section “Desoldering” later in this chapter.
