6.3 Building the Power Supply PCB
Before we begin, let's take a moment to talk about installing and checking resistors.
Hold the lead that you are about to clip with one hand so that it does not go flying off and hit
you in the face or the eye! Orient your resistors so that the color codes can be read from left to
right so it will be easy to match up with pictures in this manual or on your disk.
Take your time and take a break from time to time. While it's not necessary, you can solder
through hole resistors on the top as well as the bottom, if you prefer. But don't use to much
solder; you don't want create blobs, just a good connection.
When you're done, here's a way to double check your connections:
1. Set your multimeter to the Ohm position.
2. Touch one end to the lead of a resistor above the PCB (not the PCB solder pad to which
it's connected).
3. Touch the other end to a distant point that is directly connected (i.e., with no additional
resistance) to the other end of the resistor. (You'll may have to flip the PCB over and
back to determine where to position the lead.) You'll then be able to both read the value
of that resistor and assure yourself that both leads are properly soldered
. If some part
of this path has a large capacitor in it, it may take a little time to register the value of
the resistor you're expecting.
