How to solder through-hole components – another teaching moment from Digi-Key
Do you have everything you need to solder, but are unsure exactly how to go about it? This Another Teaching Moment video demonstrates the basic process of through-hole soldering to help you get started on small-scale projects. You will need a soldering iron or station, flux core solder and safety glasses. You may also use a fume extractor to remove potentially harmful flux fumes if your room is not well ventilated.
Safety is of the utmost importance, so put on safety glasses and turn on a fume extractor while your soldering iron heats up. Then follow the step-by-step instructions in this video tutorial to learn how to solder through-hole electronic components, from cleaning the tip before you start to removing flux residue from your circuit board when you are finished. The video highlights a good “chocolate kiss” solder joint and explains what to do if you end up with a bad solder joint, including those with no connection to the pad, no connection to the post, a short or bridge between two posts, and too much or not enough solder. This video will also teach you when to use a flux pen, a flux remover pen, solder wick and tip tinning paste.
