Insert the leads of the .1 µF capacitor through the holes indicated in step 7. The capacitor will have markings on it indicating its capacitance. The direction of the capacitor does not matter.

Be sure to route the leads so that they do not cover any needed holes from steps 7 and 8. Also, do not allow the leads to contact the leads of other components.

Solder the capacitor to the PCB and clip the excess leads off.
