CAPACITORS
Now it is time to install the last, and perhaps the tallest, of our PCB components – the capacitors. The radial capacitors we’re using already have their leads in position. Simply insert each part into the designated pair of holes on top of the PCB and bend its leads over on the bottom.

Fig. 62 Hold the electrolytic capacitor flat to the PCB surface while bending its leads outwards underneath. This will hold it in place for soldering.

Fig. 63 Film bypass capacitors, if used, are installed in the same manner.

Fig. 64 With all capacitors installed and leads bent, it's time to turn over the PCB for soldering..

Fig. 65 Apply heat to both the capacitor lead and surrounding plated hole, and flow solder to complete the joint.

Fig. 66 With all joints soldered and leads clipped, the bottom of the PCB should look similar to this.

Fig. 67 Congratulations! All of your through-hole circuit board components have now been soldered in place. Next, we'll add an output transformer before installing the module hardware and enclosure.
