0805, 1206, SOT23 and other small pin count chips

  1. Apply solder to one of the pads. For a part with more than three pins, apply solder to a corner pin. If you are right-handed, apply solder to the right hand pad(s). Rotate the PCB so the chip has a right-left orientation instead of top-down orientation.
  2. Use a pair of tweezers to handle the component.
  3. Place the soldering iron on the pad to keep the solder molten, then place the component on the pad.
  4. Remove the soldering iron when solder flows up the component.
  5. Let the solder solidify.
  6. Release the component from the tweezers.
  7. Double check the orientation and alignment. You can easily fix any problem at this stage just by reflowing (melting) the only soldered pin/pad and use the tweezers to adjust the alignment.
  8. Solder the other pin(s).
