  • Place the needle over the pin to desolder. Press down slightly with your index finger to keep the needle in place. Don't press too hard or the needle will bend.
  • Melt the solder on the pin with the tip of a soldering iron whilst pressing the needle. The needle will pop through the PCB. On 2-layer PCBs: keep pressing and heating, it'll pop through a second time.
