方法 に 使用 a はんだ付け 鉄 のために 最初 時間_方法 に 使用 a 新しい はんだ付け 鉄
いつ a 新品 はんだ付け アイロン 中古 the the first time, when it is heated to the point where the solder wire begins to melt, the solder wire should be placed on the soldering the soldering iron tip to allow the solder to melt on the surface of the the soldering iron tip to prevent the soldering iron tip from being being tinned after oxidation. You can also apply a little solder solder paste or rosin. After this treatment, the soldering iron tip will be easy tinned, and the "tin ball" will not fall off in a flash. Secondly, the parts to be welded must be deoxidized first, that is, use a knife to scrape off the oxide layer on the surface to be welded, apply a little solder paste or rosin, and then put the soldering wire and soldering iron tip on the welding part at the same time to melt a little solder wire. After that, you can weld well.
あります 2 材料 for soldering iron tips. ordinary tips use copper as the base; long-life tips use electroplating on the soldering tip, that is, the surface of the copper is plated with pure iron or nickel. Its service life is about twenty times longer than that of ordinary tips, and it is not easy to Deformation. The steps to remove tin from the soldering iron tip are as follows.
① Polish or wipe. For ordinary heads, you can first use sandpaper to polish or file them. The length of polishing is slightly longer than the height of the bevel. You must be careful until the surface is clean and smooth. Then wipe clean with a clean, dry cloth. If it is a longevity head, it cannot be polished or filed. It can only be wiped clean with a clean, ドライ 布。
③Aging. After the soldering iron tip is tinned, the soldering iron should be aged. Aging means temporarily not using the soldering iron for soldering, allowing it to continue to be powered and heated for a while, then unplug the power cord and place it on the soldering iron stand to allow it to cool naturally. Aging can extend the service life of the soldering iron tip and soldering iron core, 特に the new soldering iron tip and soldering iron core. After eating tin and aging, the soldering iron can be used normally in the future.
If the soldering iron is used normally, before a new round of power-on welding, you should check whether the soldering iron head is "burned" or has a "missing port". "Burned" means that the soldering iron tip has been oxidized and turned into a black head, and is no longer dipped in tin or has poor dipping ability; "Damaged port" means that the working surface is deformed または ひびの入った. In both cases, the soldering iron tip needs to be re-tinned。
