Since we have done quite a few product reviews lately, we have decided a basic “how-to” article would be an appropriate post. The following is a series of steps to take when practicing the art of basic circuit board soldering.
First of all, you need to make sure you have all of the equipment that you need: a solder iron and solder. You should choose the appropriate iron based on the type of soldering you will be doing. In addition to this, you will need to choose a type of solder. If you’re working with electronics or circuit boards, be careful not to use acid core solder because of its corrosive nature.
Next, after you have all the right equipment, you should prepare your surface. The surface should be clean and all of the surfaces that are going to be soldered should be cleaned with a solvent and steel wool. All of your equipment should be free from debris as well.
Now you can start the actual soldering process. Bend the leads of the component and fit them through the correct holes in the board. Touch the pad and the lead with the iron’s tip to allow them both to heat up. After both are properly heated, you can begin soldering. The result should be a shiny connection with no cold joints (bubbles in solder).
After you have soldered everything that you need to, you need to clean up using solvent or steel wool to remove the extra rosin.
Check out this video on circuit board soldering. It goes a little more in-depth than my post, and gives you a visual reference as well.
