Now comes our electronic engineer's favorite part. The part when they can finally solder the components onto the board and say out laud that the board is ready. You can learn more about burnishing and soldering from the screenshots we have provided for you. After you completed this tutorial only testing remains which you can learn about in the next tutorial.

Screenshots below:

Figure 1 - Burnish smoothly the surface of the PCB board with a sandpaper

Figure 2 - Put wires through the vias and solder them. We advise copper wires.

Figure 3 - Solder remaining components onto the board

Figure 4 - The finished PCB board. To test it out, jump to the next tutorial.
