ESD
stands for Electrostatic Discharge or simply static electricity. It is caused by
the buildup of electrical charge on one surface that is suddenly transferred to
another surface when it is touched. Computer components and integrated circuits
such as motherboards, memory modules and hard drives, are especially susceptible
to ESD damage.
Here
are some ways you can avoid it:
-
Use a commercial grounding
strap when handling components. Do NOT improvise and make your own strap.
Commercial grounding straps are specially designed to include a large
resistor that protects you in the event that you accidentally touch live
power while grounded.
-
If you don’t have a
grounding strap, ground yourself before working by touching the exterior
metal box of your PC’s power supply before unplugging it. This will zap
out any ESD buildup in your body.
-
Work in a static-safe station. An uncarpeted room with a controlled humidity works well.
But if you must
work in a room with a carpet, do not go walking about while wearing socks as
this could generate static electricity quickly. Clear your workbench
of plastic bags and other objects that are prone to ESD.
-
Always handle components by
the edges. You will considerably reduce the chance of zapping components
by avoiding touching any pins, wirings or chips.
-
As much as possible, keep your
component inside the antistatic packaging that came with it until you are ready to install.
