How to Solder

Soldering is the process of using a filler material ( solder ) to join pieces of metallic element together. Soldering occurs at relatively low temperatures ( around 400 degrees Fahrenheit ) as compared to brazing and weld, which actually melt and fuse the materials themselves at higher temperatures. In soldering the filler material becomes liquid, coats the pieces it is brought into reach with, and is then allowed to cool. As the solder cools it hardens, and the two materials are joined. Soldering is a quick way to join many types of materials, from bull shriek to stained field glass. It creates an electrically conductive strong bond between components that can be re-heated ( desoldered ) if you should ever want to disconnect two items joined together. It ‘s big for joining electric components and wires and is used in fair about everything electronic. In this Instructable I explain how to solder the basics you see in most Instructables : electric components and wires. For promote data and some more technical specification on soldering check out the wikipedia article. As with many skills, having the right tools for the speculate effects the quality of the exercise being done. When it comes to soldering you can end up using a set of visualize tools, or barely a few simple items you can pick up at the hardware store for a couple of bucks. I am going to use a copulate of different solder tools in this Instructable ; there are many ways to solder, and you should use what works for you. At the very minimum you will need the solder and a heat source to melt it – preferably something little which can get to 600-800 degrees Fahrenheit. If you ‘ve got that, your ready to make a connection. That being said, there are a wide roll of bonding tools and accessories that can be actually helpful if you ‘re going to be soldering frequently. Ladyada has compiled a nice list of equipment and sources to buy the tools on her site. I got together a solid supply of soldering tools by raiding the Squid Labs soldering station. here is the complete list of what I used …

1. Soldering iron
Most people opt for using a soldering iron to solder. It ‘s a capital hotness source that heats up and cools down promptly and can maintain a pretty constant temperature. Soldering irons can be purchased from a assortment of places. I have picked up some at Radioshack – evil yes, but convenient, some from the hardware store, some from garage sales and a bunch together more from retailers online. low electrical power ( 15-40 watt ) soldering irons work well for soldering components on racing circuit boards while more mighty ( 60-140 watt ) soldering irons work well joining slurred materials like braided speaker wire. If you use excessively knock-down of a soldering iron on a circuit board you might damage the components you are trying to join. I like to keep a low-wattage iron around for detail study, and a high-wattage iron that I can use when I am not excessively concerned about exposing the corporeal I am working with to high temperatures. It ‘s a real pain to solder thick wires without a brawny solder iron. The soldering iron in most of the pictures is made by Weller, and has a variable temperature control. This is the best of both worlds since you can set the heat precisely where you want it, but it ‘s significantly more expensive than fixed-temperature irons. If you ‘re fair going to do some episodic solder it is n’t a must have by any means. Anyone matter to in modding a soldering iron should check out DIY Hot Air Soldering Iron by charper. 2. Solder
There are lots of kinds of solder available. They come in different thicknesses from around .02 ” to some very thick stuff you would entirely use on copper organ pipe with a butane torch. You use sparse solder for detail work like putting resistors onto circuit boards and thick solder for joining larger materials like speaker wire. I use solder around .025 ” for most jobs. Most solder is made from a combination of tin and head – it ‘s about a 60 % tin, 40 % tip mix depending on what solder your using. recent international health codes from Japan and the EU ( California and New York have adopted exchangeable policies as well ) mandate that lead solder be phased out of certain commercial products and substituted with a lead-free alternate. The manufacturing deadline was this past July so we should be seeing the changes immediately. even if you do n’t live in California or New York its still worth staying away from head solder since lead has been known to cause all kinds of a filthy health effects from birth defects to severe developmental and neurological damage. Plus it ‘s pretty easy to find the lead-free stuff. Some solder will contain a little total of silver. This pushes the mellow temperature up a act, but the silver helps the solder to flow and makes a stronger joint. If you are disquieted about burning whatever your working with, try to stay away from solder with argent in it, but it works very well if you ‘re fair joining wires or something that wo n’t be well damaged. The last thing to know about solder is that you want to use a solder that has a rosin kernel. The rosin acts as a flux density when bonding and helps the connection – it ‘s besides the kind that ‘s most promptly available at the hardware store and from electronics suppliers. 3. Soldering iron tips
Soldering irons come with a point, so you do n’t have to go out and get a special one, but it ‘s authoritative to know the differences between them and make sure you ‘re using the right lean for the kind of soldering you ‘re doing. Some small-wattage irons come with conic pointed tips for detail work, while most high-wattage irons come with a compressed screwdriver-style tip that works well on wires. You want your tip to be a small smaller than whatever you are soldering sol you have adept control of what you heat up and what you leave alone.

4. Soldering iron holder and cleaning sponge
It ‘s nice to have a safe stead to put the bonding iron down in between soldering. A solder stand safely holds the iron and gives you a place to clean the tip off. Some solder irons come with their own holders. If yours does n’t have one, you can buy one or make one. jaime9999 has a Homemade nearly-free Soldering Iron Stand that is pretty much identical to what you can buy. The stand is n’t a necessity for learning how to solder, but it does help. 5. Tools to work with wires
I have a go-to stock of tools that I round up when working with wires or electrical components. They consist of wire cutters, a cable stripper, needle nose pliers, and an automatic wire stripper well ( courtesy of the Squid Labs soldering station. ) The automatic rifle wire stripper is in truth commodious if you ‘re going to be stripping lots and lots of cable, but by no means necessity. I have stripped lots and lots of speaker telegram using my teeth ( not the best idea, I know I know. ) 6. Clips to hold your work
Often called “ third base hands ” or “ helping hands, ” these little guys help a whole fortune when soldering. You have to hold the soldering iron with one hand and the solder telegram in the other, so it actually helps to have something else to hold the components you ‘re actually trying to join. You can use alligator clips, clamps, or even some tape to hold things in invest if you need to. The one-third hand is by and large a well investment if your going to be soldering regularly, and there are batch of Instructables with with ideas to modify them if you do happen to pick one up. Check out : Make a 3 degree of freedom ‘hand ‘ to help with soldering / glue work and make your ‘helping hands ‘ 100x more useful for soldering / gluing small parts by leevonk to start. If you would like to make a set of helping hands of your own there are already a numeral of good Instructables on that besides. Quick assistant for surface-mount solder by hypertext transfer protocol : //epicentreconcerts.org/member/bikeNomad/bikeNomad, QuickMods – Soldering Arms by Aeshir and Build a Pair of Helping Hands by john otto should get things started. 7. Exhaust fan
I do most of my bonding at a soldering station that is equipped with an exhaust fan. It ‘s very not such a good theme to breathe in solder fumes, and soldering does produce fumes. Any kind of ventilation/fan you can rig up will help. Vent the fumes outside or use an indoor fan with a percolate if you ca n’t vent them outdoors. hera is a Window-mounted solder fumigate extractor ( not just for RVs ! ) posted by bikeNomad. besides check out Dr. Solomon ‘s humble technical school, but functional Solder Fume Extractor if you ‘re looking to build something that you can place right field on your postpone. If you ‘re good doing a promptly bonding job, the fumes wont kill you by any means. I have surely done my fair share of soldering without a vent, but anyone doing insistent bonding should decidedly pick one up or make one.

8. Safety goggles
I had n’t ever used goggles before while solder, but while doing inquiry for this post I saw it mentioned elsewhere and agree that its a full theme. little mellow bits of solder tend to fly out of the soldering joint when you ‘re feeding in the solder, and if it landed in your center it would n’t feel excessively good. 9. The materials that you want to join together
I was just messing around, and by and large soldering for the purpose of this Instructable so my materials did n’t necessarily make anything. You can solder wire, electrical components like resistors and capacitors, circuits, breadboards, electrodes, small pieces of metal and whatever else you can think of. Do n’t know if it can be soldered ? Give it a try – you wo n’t blow anything up. once I have got my tools and materials rounded up, I like to pretend that I am a navigate and begin my pre-flight/solder checklist .
