[summary]Soldering is a method of connecting two pieces of metal together by melting another filler metal in between them. There are many kinds of soldering, but this article is designed to teach you the basics of electrical soldering.[/summary] | |

== Background Information == | |
- | First used in the second generation of computers back in the 1950's, through-hole soldering is the simplest form of soldering in which leads on the components are inserted into plated through-holes (PTH). The leads are then soldered to pads on the opposite side of the PTH. |

The leads are then soldered to pads on the opposite side of the PTH. |
Though it provides very strong mechanical bonds, drilling the additional holes in the printed circuit boards makes it much more expensive than other methods such as surface mounting. | |

- | Soldering can be dangerous if you don't follow a few basic safety procedures. You are working with tools that are hot, and melted metals. You want to make sure you don't burn yourself. It's a good idea not to wear loose fitting clothing that could get in the way when you are working, as well as tie your hair back if it is long. It is also important to wash your hands after you do any soldering. Some solder contains lead, and you don't want to be eating that. |

+ | Many solders contain flux. This is usually rosin flux and vaporizes when heated to the melting point of the solder. Inhaling these fumes is bad for you. This fume is one of the most significant causes of occupational asthma in the US. If you are doing 'hobby-level' amounts of soldering then you might not find the fumes significant - it may be sufficient to keep a nearby window open for ventilation and/or use a fan to blow/suck the fumes away from your face. If you are concerned, or are working in a more industrial environment then N95/K95 or higher masks will work just fine to keep it out of your lungs (not your eyes though), but a half-face respirator is cheap and the filters last a long time. Buy P95 or P100-rated filters. Some people just use a solder fume extractor, fan, or hood to move the fumes away, but the effectiveness of these methods is of course very variable and as such are not recommended as the only solution. |

+ | Soldering is a fire hazard. Hot irons and solvents, carpets, certain clothing fabrics, etc, can combine to cause fire. Usually, this fire appears quickly and you are at the center of it. Don't let those hip kids in the other lab fool you, being on fire really, really sucks. A lot. Get a fire extinguisher and keep it near your work bench. |
The four basic safety rules: | |
- | * The iron is hot. |
- | * The fumes are not fun. Work in a well ventilated area. |
- | * Always wear safety goggles. Flying molten lead hurts. |
- | * Wash those lead-y hands after soldering before touching your face or eating. |
+ | * ***The iron is hot***. Very hot. You will burn yourself from time to time but these are rarely anything to be concerned about. |
+ | * ***Work in a well-ventilated area.*** The fumes are not fun. |
+ | * ***Always wear safety goggles.*** Flying molten lead hurts and both solder and flux can splash. |
+ | * ***Wash your hands, ya filthy animal!*** Leaded solder contains lead (!). 'Hobby'-levels of leaded soldering do not represent a significant health risk, although you should wash your hands after handling it, especially before eating, smoking, and interacting with children, who are especially sensitive to the effects of lead exposure. |
+ | ** Solid lead cannot pass the skin barrier, it enters the body through ingestion or the mucous membranes, lead dust is dangerous because it can be inhaled, so you should take care when cutting or filing circuit boards (for example, when salvaging components). |
+ | ** Soldering iron temperatures are not high enough to turn lead into a vapor so there is negligible risk of 'breathing in lead' - most of the smoke you see is the flux burning off. |
== Equipment == | |
A soldering iron is a pen shaped tool with a fine tip that heats up. One of the ways soldering irons are measured by is wattage. For most basic soldering, a 25 to 50 Watt soldering iron will work without any problems. Most irons are simple single temperature models, but it is also possible to buy advanced solder stations where you can directly set the tip temperature with a dial or knob. | |
+ | iFixit sells a Smart Soldering Iron that is portable, 100W, USB-C powered, and heats up in under 5 seconds. Check it out! |

=== Iron Stand === | |
A soldering iron stand is used to keep the hot tip of the soldering iron from burning the table or work surface when you set the iron down. They are often included with higher end soldering irons, but must be purchased separately with most budget models. | |

+ | iFixit sells a Portable Soldering Station that makes it easy to take your Soldering Iron wherever you need to go. |

=== Solder === | |
For someone just starting out and learning how to solder, using leaded solder will be much easier. | |
