The final touch is cleaning the board. As you can see on Figure 24, after removing the component the board will have a brown resin all around the component holes. To remove this brown resin, use a small flat-tip screwdriver, as we show on Figure 25. Don’t push the screwdriver too hard or you will remove the board lacquer (green on the board we used in our example).
