| + | [title] Solder the first resistor |
|---|---|
| + | [* icon_note] 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. |
| + | [* black] Press the tip against the circuit board's solder pad and the resistor's shiny edge for a few seconds to heat them both. Angle the tip so it has maximum contact with the pad and lead. |
| + | [* icon_caution] If you heat the circuit board continuously for more than 10 seconds, the excessive heat may damage the solder pad or resistor. |
| + | [* black] Feed the solder wire into the heated area until there's a concave pool ("[link|https://guide-images.cdn.ifixit.com/igi/2Oc3NckhSmri23jf.full|mini volcano|new_window=true]") of solder surrounding the lead. |
| + | [* 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. |
| + | [* icon_note] 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. |
| + | [* black] Remove the solder wire first, then remove the soldering iron from the pad. |
| + | [* black] Repeat this process for the resistor's second shiny edge. |
