In order to avoid ESD, it helps to know
the conditions in which it is most likely to occur. When the humidity
is low, the potential for ESD increases dramatically. Also, if the
temperature is cool or if there is carpeting on the floor, the
potential for static electricity is higher.
 A few
key elements to include in a good working area should be anti-static
tile on the floors, grounded workbenches with anti-static mats, and
wrist straps. The area should be clean and well lit. It should have a
climate control system that raises the relative humidity above 50
percent. If all of these elements are in place, the risk of ESD will
be significantly reduced. Students should use Figure
Once the computer case has been opened, the technician should be grounded to the case by touching an exposed part of the computer case. If just a painted part of the case is touched, it may not release any static buildup. Once any static buildup has been discharged onto the exposed case, make sure to attach the grounding wrist strap to the case to help prevent any more buildup. An ESD free environment is crucial to preventive maintenance that involves opening the computer case. |
