6.2 Soldering Procedure
- Ensure your work area is clean and well-ventilated.
- Clean the soldering tip by wiping it on a damp esponja o llana de llautó.
- Apply a small amount of solder to the tip (tinning) to improve heat transfer and prevent oxidation.
- Place the hot tip against both the component lead and the PCB pad you wish to solder, ensuring good contact with both surfaces.
- Feed solder onto the joint, not directly onto the iron tip. Allow the solder to flow evenly around the joint.
- Remove the solder wire, then remove the soldering iron. Allow the joint to cool naturally without disturbance.
