  • Congratulations—you've created a solder joint! Inspect the joint to see if it formed correctly:

  • Leaded solder joints should look like a shiny, concave tent surrounding the entire lead.

  • If the joint isn't shiny, it may not have formed correctly. Reheat the joint briefly and allow it to cool.

  • Lead-free solder joints should look like a concave tent surrounding the entire lead. They may be shiny or dull.

  • If the solder joint doesn't surround the entire lead, reheat the joint and add more solder.

  • If the solder looks like a round bead instead of a concave tent, it didn't bond to the component lead. Reheat the joint and try to get the lead hot enough so the solder bonds to it.

  • Check if any solder unintentionally bridged with a different joint. If so, apply some flux and reheat one of the joints to carefully break the bridge. If the bridge doesn't want to separate follow this step and use solder wick to pull away any extra solder.

  • Like any skill, practice makes perfect. If your first solder joint doesn't look picture-perfect, that's OK! It takes a few attempts to get the hang of the movement and timing.

恭喜你——你已经创建了一个焊点！检查焊点是否形成正确：

含铅焊点看起来应像一个闪亮的凸起帐篷，包围着整个引线

如果接头不光亮，则可能成型不正确。重新加热接头，然后让其冷却。

无铅焊点看起来应该像一个凹陷的帐篷，包围着整个引线。它们可能闪亮，也可能暗淡。

如果焊点没有包围整个引线，请重新加热焊点并添加更多焊料。

如果焊料看起来像圆珠而不是凹陷帐篷，则表示它没有与元件引线粘合。重新加热接头，并尝试使引线足够热，以便焊料与其粘合。

检查是否有任何焊料无意中与其他接头桥接。如果是这样，请涂抹一些助焊剂并重新加热其中一个接头以小心地断开桥接。如果桥接不想分离，请按照此步骤并使用吸锡线拉走任何多余的焊料。

和任何技能一样，熟能生巧。如果您的第一个焊点看起来不完美，那也没关系！需要尝试几次才能掌握动作和时间。
