2-1. Installing the Motherboard to the Chassis
Most computer chassis will have a base on which there will be many mounting holes that allows the
motherboard to be securely attached and at the same time, prevents short circuits. There are two ways to
attach the motherboard to the base of chassis:
!
with studs
!
or with spacers
Please refer to figure 2-1, which shows the studs and spacers. There may be several types, but all look
like the figures below:
In principle, the best way to attach the motherboard is with
studs. Only if you are unable to do this should you attach
the board with spacers. Take a careful look at the
motherboard and you will see many mounting holes on it.
Line these holes up with the mounting holes on the base. If
the holes line up and there are screw holes this means you
can attach the motherboard with studs. If the holes line up
and there are only slots, this means you can only attach the
motherboard with spacers. Take the tip of the spacers and
insert them into the slots. After doing this to all the slots,
you can slide the motherboard into position aligned with
the slots. After the motherboard has been positioned,
check to make sure everything is OK before putting the
casing back on.
Figure 2-2 shows you the way to affix the motherboard
using studs or spacers.
Note
If the motherboard has mounting holes, but they don’t line up with the holes on the base and there are
no slots to attach the spacers, don’t worry, you can still attach the spacers to the mounting holes. Just
cut the bottom portion of spacers (the spacer they may be a little hard to cut, so be careful with your
hands). In this way you can still attach the motherboard to the base without worrying about short
circuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboard
PCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contact
any the printed circuit wire or parts on the PCB that are near the fixing hole, otherwise it may damage
the board or cause board malfunctioning.
