| + | [title] Solder the resistor |
|---|---|
| [* icon_note] You're going to heat the solder pad and the resistor's lead ***very hot for 2 to 3 seconds***. The pad and lead should readily melt the solder wire. | |
| [* black] Press the tip against the circuit board's solder pad and the resistor's lead for about 1 second to heat them both. Angle the tip so it has maximum contact with the pad and lead. | |
| [* icon_note] If you're using a narrow soldering tip or working with a large solder pad, you may not be able to transfer enough heat to the area. You can try increasing the temperature by 50°C or switch to a larger tip for more effective heat transfer. | |
| [* icon_caution] If you heat the circuit board continuously for more than 10 seconds, the excessive heat may damage the solder pad or component. | |
| [* black] Feed the solder wire into the heated area until there's a concave pool ("mini volcano") of solder surrounding the lead. | |
| [* icon_note] This should happen within a few seconds. If the solder doesn't adhere to the pad, apply flux to the pad or increase the temperature. | |
| [* icon_note] Don't feed the solder directly onto the tip as it won't flow properly into the pad and lead causing a weak connection. | |
| [* black] Remove the solder wire, then remove the soldering iron from the solder pad. |
