Set up tools
Use a temperature-controlled iron, tip cleaner, flux, solder, and fume extraction.
Prepare joints
Tin the iron tip, apply flux to pads, and insert components securely.
Solder technique
Heat pad and lead together, feed solder to the joint, and remove iron smoothly.
Inspect and clean
Look for shiny, concave joints; fix bridges and clean flux residue where needed.
