How to Solder¤

Soldering is a process in which we heat and join two (or more) components using flux and solder.

Preparation¤

  • Sponge: Wet the sponge before starting. After every soldered joint, first wipe the tip on the sponge and then place it in the holder.
  • Flux: It aids in better solder wettability and helps create a conductive, smooth, and good-looking joint.
  • Soldering Station:
    • Transformer Soldering Iron: It is larger and heavier.
    • Micro-soldering Iron: Heats continuously during operation, not only when the button is pressed, unlike the transformer soldering iron. The temperature is adjustable and regulated, preventing damage to the soldering tip.
      • Set the micro-soldering iron to a temperature of 300 °C.

Types of Soldering¤

  • THT (Through-hole technology) - soldering components with metal legs that are inserted through holes in the printed circuit board.
  • SMD (Surface-mount technology) - soldering components with metal bands that are pasted onto the printed circuit board.
