Install toroidal inductor L3 and solder both leads. Check for

continuity (less than 1 ohm) between the solder pads.

i

Do NOT attach L3 or T1 to the circuit board with adhesive

or other compounds. They should be supported only by their
leads.

Install two pairs of standoffs in the holes at the edges of the board

as shown in Figure 20. The front panel / top cover will attach to the
short standoff. One pair of standoffs installs near J8 and K2 (on the
bottom face of the board) and the other pair installs in the hole near P1
and J6.

Place the front panel (top cover) face down on a soft cloth to

avoid scratching it.

Remove the paint from around the screw holes where the short

standoffs will contact the front panel as shown in

Figure 21

. Use

sandpaper or a sharp knife. Clean the panel thoroughly to remove all
of the residue when you are done.

Inspect the area where the thermal pad will mount and be certain

there are no burrs that could poke through the thermal pad. Burrs are
most likely to be found around the hole. Sand file any rough edges
smooth.
