Electro-Static Discharge Precautions
Integrated circuit components in these products can be damaged by electro-static discharge. It
doesn't make any difference whether the IC's are installed on a printed circuit board or laying
on a table. Static charges can build up in people to a potential of several thousand volts by
simply walking across a room.
These circuits in the computer, bus
expander~
accessories and peripherals can be protected
by using a static free workstation and wearing clothes that do not hold static charges before
handling any of the unit's PC boards.
'When you need to remove or install a part, remove power from the product first. With the static
free workstation in place, touch sheet metal with your fingers before touching the printed circuit
assembly. If the assembly is not going to be re-installed, place the assembly in an anti-static
bag and set it aside.
Following these precautions will extend the life of the computer products you maintain.
