Protection Against Electrostatic Discharge (ESD)
Integrated circuits are sensitive to ESD.To avoid damage caused by ESD, service engineers
and other people must handle equipment and boards carefully.
Electronic equipment has become more resistive to ESD, but we see an increase of
situations where static electricity can build up. This is caused by an increasing application
of man–made fibres like nylon, acrylic, etc. which are capable of generating ESD of 10,000
Volts and more.
Walking across a nylon carpet, even for a few feet, could cause a person to be charged–up
to more than 10,000 Volts.
Under these conditions, if a system board or a (C)MOS device is touched it could easily be
damaged. Although the device may not be totally defective, it is often degraded, causing
it to fail at a later date without apparent reason.
To make sure that equipment and parts are well protected during shipment, special
packaging materials are utilized. System boards will be shipped in anti–static bags and
(C)MOS devices and other sensitive parts in small shielded boxes.
3.2.1
ESD Handling
In the interest of quality and reliability, it is advisable to observe the following rules when
handling system parts:
• Keep parts in their protective packaging until they are needed.
• When returning system parts like EEPROMS to the factory, use the protective
packaging as described.
• Never underestimate the damaging power ESD can have and be especially careful
when temperatures are below freezing point and during very warm weather in
combination with low humidity. Make sure that the environmental conditions remain
within the limits specified in the components’ data sheets.

IMPORTANT NOTE
In the interest of quality and reliability system boards and other parts returned
for exchange or credit may be refused if the proper protective packaging is omit-
ted!
