First of all, it must prepare the surface edge to soldering before, is clean, bright, by using a cutter or sandpaper or scrapers to clean the solder point, but do not rub or scratch off the force because of sensitive electronic equipment mostly scrubbing vigorously beware, broken leg.Cleaning the soldering point enough, then just remove the soldering iron comes in plug. Wait until the soldering iron is hot. Enough to make the lead melted, which is in the range of 15 seconds to 1 minute, but the brand and size of the soldering iron heating test by removing the lead come tae. See the solder tip If melted use when soldering iron is hot then remove the solder tip to focus with the soldering point and then took the lead dipped to solder soldering iron directly between the. If a 30-watt soldering iron, it can raise the soldering iron away from the soldering of lead dissolve as soon as solder points throughout the ironclad, but if using a soldering iron, heat is lower than this, it provides immersion soldering iron solder point again for a while (2-3 seconds) and then split out.After removing the soldering iron away from the solder, then, blown by the mouth lead to hardening, but if the solder points is faster, it does not have to blow a little, because the lead almost as soon as it lifted off from the soldering iron solder point.
