3.1.1 Electrostatic Discharge (ESD)
When handling disconnected devices, electrostatic discharge (ESD) can cause damage
if discharged into or near sensitive components on the device. Take steps to avoid
such an occurrence.
HBM uses state-of-the-art electronic components in its equipment. These electronic compo-
nents can be damaged by discharge of static electricity (ESD). ESD damage is quite easy to
induce, often hard to detect, and always costly. Therefore, we must emphasize the impor-
tance of ESD preventions when handling a GEN7iB system, its connections or a plug-in card.
Description of ESD
Static electricity is an electrical charge caused by the buildup of excess electrons on
the surface of a material. To most people, static electricity and ESD are nothing more
thanannoyances.Forexample,afterwalkingoveracarpetwhilescungyourfeet,
building up electrons on your body, you may get a shock - the discharge event - when
you touch a metal doorknob. This little shock discharges the built-up static electricity.
ESD-susceptible equipment
Even a small amount of ESD can harm circuitry, so when working with electronic
devices, take measures to help protect the electronic devices, including the GEN7iB
data acquisition system, from ESD harm. Although HBM has built protections against
ESD into its products, ESD exists and, unless neutralized, could build up to levels that
could harm the equipment. Any electronic device that contains an external entry point
for plugging in anything from cables to acquisition cards is susceptible to entry of ESD.
Precautions against ESD
Any built-up static electricity should be discharged from the user and the electronic
devices before touching an electronic device, before connecting one device to another,
or replacing acquisition cards. This can be done in many ways, including the following:
● Grounding oneself by touching a metal surface that is at earth ground. For
example, if the computer has a metal case and is plugged into a standard three-
prong grounded outlet, touching the case should discharge the ESD on the body.
● Increasing the relative humidity of the environment.
● InstallingESD-specicpreventionitems,suchasgroundingmatsandwriststraps.
