Tips for soldering

I noticed that diy forum mentions many diy projects with soldering but lacks instructions as how to solder properly. These are a few video clips that I downloaded from a website a few years ago showing how to solder properly. Hope this helps anyone without proper knowledge in soldering.

Those are very nice instructional videos. Definitely a must-see for anyone not familliar with soldering.

 

Are you the one doing the narrating?

Very nice videos thanx for the tutorial. I would love some video on proper technique for removing solder from a joint...the tools involved etc...

lol. It's not me doing the soldering. I wish I could solder that well. Wires connect better when soldered and would protect better against moisture if used with shrink wrap tubing than using stand elecrical tape. Make sure to have proper ventilation when you solder. Those fumes are supposed to be harmful when inhaled.

 

(edit) here is a quck link for heat shrink.

Awesome tutorial eastgokki!

 

The rosin flux is not particularly harmful, but it is organic and some individuals can have a potentially lethal allergic reaction to the flux and the fumes. As with all smoke, it does create some health risks, but for the amount of soldering a hobbyist does, it isn't a general concern. It doesn't hurt to have the area ventilated, but keep airflow near the work itself fairly still. Too much airflow can keep your work too cool for a proper solder joint to form, and you wind up with the infamous "cold solder" joint. It will come back to haunt you later. Another point to note is that you do not want to use acid flux on anything electrical. It is corrosive and conductive and not appropriate. It is great for plumbing, terrible for wiring. Use only a rosin flux.

 

Removal of solder is fairly straightforward Tegallegos. You can purchase a "solder sucker" tool, but I'm not much of a fan of them. I prefer desoldering braid. It is a braided "wire" made of fine copper strands. You heat your solder joint, then touch the desoldering braid to the molten solder. The bulk of the solder will be drawn up into the braid, and your joint should now be free.

 

The only thing that video was missing was a mention of the proper way to splice wires. There are a number of ways, but the western union splice is by far the best. The idea is to create a good mechanical connection BEFORE applying solder. Here's a page detailing the process. Splicing wires

 

I second the heat shrink tubing. It seals better, is easier to apply neatly, and results in a much more professional result. The drawback is that it requires forethought in putting the heat shrink on each wire before soldering. Theres a short video on the next page of gokki's link, where the demonstration uses a lighter. This works, and I'll use a lighter in small spaces or when more convenient. You do risk burning and ruining your wires and heat shrink, however, if you are not very quick and do not keep the flame moving. A heat gun is the proper tool for the job, but most laides' hair dryers can produce a high enough temperature for heat shrink tubing and are a good substitute.
