FIGURE 1-2:
Notice that all electronic components such as LEDs, PIC
and multiplexer ICs are mounted on the bottom side of the board to create a flat surface
to accommodate the top layer. A clear acrylic cover plate with a decorative silk screen
is mounted over the PCB using a double-sided adhesive tape (see Figure 1-3).
