Methods are as follows:
Tools/Materials
1, a soldering iron
2, a soldering wire
3, to be soldered components
Methods/Steps
1, prepare the soldering wire and soldering iron The soldering iron and the soldering wire are ready. At this moment, special emphasis on the head of the soldering iron to adhere to the clean, that can be stained with solder (commonly known as eating tin).
2, the soldering iron touch welding point, pay attention to the first to adhere to the soldering iron to heat all parts of the weldment, such as printed circuit boards on the leads and pads are heated, and secondly, pay attention to the flat part of the soldering iron head (the larger part of the soldering iron head to touch the larger capacity of the soldering iron head of the side or marginal part of the soldering iron head to touch the smaller capacity of the soldering iron head in order to insist on the soldering parts of the uniform heat.
3, when the solder is heated to the temperature that can melt the solder will be placed in the soldering point, the solder began to melt and wet soldering point.
4, when melting a certain amount of solder will be removed from the wire.
5, when the solder thoroughly wet soldering point after removing the iron, pay attention to remove the iron should be roughly 45 ° direction.
