Chapter 2SD7-533 Motherboard2-22-1. Installing the Motherboard to the ChassisMost computer chassis will have a base on which there will be many mounting holes that allows themotherboard to be securely attached and at the same time, prevents short circuits. There are two ways toattach the motherboard to the base of chassis:! With studs! Or with spacersPlease refer to figure 2-1, which shows the studs and spacers. There may be several types, but all looklike the figures below:In principle, the best way to attach the motherboard is withstuds. Only if you are unable to do this should you attachthe board with spacers. Take a careful look at themotherboard and you will see many mounting holes on it.Line these holes up with the mounting holes on the base. Ifthe holes line up and there are screw holes this means youcan attach the motherboard with studs. If the holes line upand there are only slots, this means you can only attach themotherboard with spacers. Take the tip of the spacers andinsert them into the slots. After doing this to all the slots,you can slide the motherboard into position aligned withthe slots. After the motherboard has been positioned,check to make sure everything is OK before putting thecasing back on.Figure 2-2 shows you the way to affix the motherboardusing studs or spacers.NoteIf the motherboard has mounting holes, but they don’t line up with the holes on the base and there areno slots to attach the spacers, don’t worry, you can still attach the spacers to the mounting holes. Justcut the bottom portion of spacers (the spacer they may be a little hard to cut, so be careful with yourhands). In this way you can still attach the motherboard to the base without worrying about shortcircuits. Sometimes you may need to use the plastic springs to isolate the screw from the motherboardPCB surface, because the circuit wire may be near by the hole. Be careful, don’t let the screw contactany the printed circuit wire or parts on the PCB that are near the fixing hole, otherwise it may damagethe board or cause board malfunctioning.
