14. From the "DUT side" of the PCB snap the spacer- grom-
mets into the holes at the four corners of the PCB. Notice
that the holes are slightly rectangular and match the spacer-
grommet's long and short sides to the holes in the PCB.
15. Apply a thin, uniform layer of thermal grease to the amplier;
a straight edge may be useful here. Position the amplier
over the mounting holes in the heatsink. Firmly push the
amplier onto the heatsink while slightly rotating the ampli-
er back and forth, ending with the mounting holes of the
amplier over the mounting holes in the heatsink.
16. Attach the amplier to the heatsink with 4-40x’ male-
female hex spacers (not supplied). These spacers serve
as alignment pins and aide in the assembly of the PCB to
the heatsink. Alternatively, use 4-40x’ machine screws
to mount the amplier to the heatsink. Do not over-tighten
the spacers or screws as this provides no thermal benet
and may break the hardware.
17. Place the PCB assembly on the heatsink/amplier assembly
so that the hex spacers come through the aligning holes
near the corners of the amplier location in the PCB. Care-
fully lower the PCB assembly until the pins of the amplier
engage the cage jacks. Alternately, sight through the align-
ing holes in the PCB and match-up the PCB to the screws
used to mount the amplier. In either case be sure the pins
of the amplier are engaged with the cage jacks and then
continue pushing the PCB assembly in the area between
the amplier’s pins until the four spacer grommets at the
four corners of the PCB touch the heatsink. At this point
the PCB should not be bowed.
18. Using #8 X 1" sheet metal screws (not provided) mount the
PCB to the heat sink at the four spacer-grommets.
19. Hook up power and signals as necessary. The amplier
is now ready for testing.
