Solder the first resistor

  • In this step, you're going to pre-load one of the resistor's pads on the board with solder. This will make it easier to solder the resistor.

  • Press the iron's tip against one of the solder pads in the outline labeled R4 for a few seconds to heat it.

  • If you heat the circuit board continuously for more than 10 seconds, the excessive heat may damage the solder pad.

  • Feed the solder wire into the heated area until there's a small glob of solder on the pad.

  • The solder should melt onto the pad within a few seconds. If the solder doesn't adhere to the pad, apply flux to the pad or increase the temperature.

  • Remove the solder wire first, then remove the soldering iron from the pad.

焊接第一个电阻

在这步，你需要用电烙铁为其中一个电阻的焊盘上锡。这将会使焊接电阻更简单。

将烙铁头按压在标有 R4 的丝印框的其中一个焊盘几秒钟以加热它。

如果持续加热电路板超过十秒，过高的温度可能会损坏焊盘。

将焊锡丝送入加热区域，直至焊盘上有一小滴焊锡。

上锡应在几秒钟内完成。若焊盘不上锡，可在焊盘上添加助焊剂或提高电烙铁的温度。

先移开焊锡丝，再将电烙铁从焊盘移开。
