It’s time to install your parts! Before soldering the diode and
transistors to your printed circuit board, make sure you thread the
leads through the correct side. The side of the printed circuit board
that has white values and outlines of the components is the correct
side. In some cases, components must be inserted into the printed
circuit board in a specific direction due to their polarity, so follow the
graphics carefully.
Note the stripe around one end of the diode. This
marks the negative (–) lead. On the printed circuit
board, the printed outline of the diode also shows
this stripe. Install the diode to match the direction
shown, and solder in place. Similarly, the transistors
are directional, and must be installed in a specific
orientation. Match the flat side of the transistors to
the outline printed on the printed circuit board.
Next, we’re going to add a bunch of resistors to our printed circuit board. As in the
previous step, you’ll find an outline of each resistor and its value printed in their proper
location on the printed circuit board. Match resistors to the values on the printed circuit
board and solder in place.
Resistors are not polarized, so it doesn’t matter which lead goes in which eyelet.
