Solder the resistor

  • In this step, you're going to heat the solder pad and the resistor's lead so that they'll readily melt the solder wire.

  • Press the tip against the circuit board's solder pad and the resistor's lead for a few seconds to heat them both. Angle the tip so it has maximum contact with the pad and lead.

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

  • Feed the solder wire into the heated area until there's a concave pool ("mini volcano") of solder surrounding the lead.

  • Don't feed the solder directly onto the tip as it won't flow properly into the pad and lead, causing a weak connection.

  • The volcano should form 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.

  • Repeat this process for the second resistor lead.

焊接电阻

在此步骤中，您将加热焊盘和电阻器的引线，以便它们能够轻易熔化焊锡丝。

将烙铁头按压在电路板的焊盘和电阻引线上几秒钟，以加热它们。调整烙铁头的角度，使其与焊盘和引线最大程度接触。

如果连续加热电路板超过 10 秒，过高的热量可能会损坏焊盘或电阻器。

将焊锡丝送入加热区域，直到在引线周围形成一个凹陷的焊锡池（“迷你火山”）。

不要将焊料直接喂到尖端上，因为焊料不会正确流入焊盘和引线，从而导致连接不牢固。

火山应在几秒钟内形成。如果焊料未粘附在焊盘上，请在焊盘上涂抹助焊剂或提高温度。

先去掉焊锡丝，再将烙铁从焊盘上移开。

对第二根电阻引线重复此过程。
