Solder Comic Feedback
Coofer Cat: “I was always taught to clean the soldering iron, then dab a tiny amount of solder onto it. This gives the iron a “liquid edge” which means it touches the pad and the lead with a greater surface, which ensures the heat is transferred (evenly and quickly). In truth, simple joints work either way, but more difficult ones benefit from this technique. Also, I was taught to look at the shape of the solder join when it’s cold. If the join has a sort of inverted curved pyramid shape around the lead, then it’s good (because the solder has properly wetted the joint), but if it’s sort of a blubous outwardly curved shape, then there’s a good chance the joint is dry (and although it may work now, it’ll probably fail in the future). Either way, this and the one-page version of it are great guides – thanks!”
