Electrostatic Discharge Precautions; Glossary Of Mnemonics - Xerox Telecopier 7033 Service Manual

6.6.2 Electrostatic Discharge
Precautions
Observe the following precautions when
handling printed wiring boards (PWBs) in the
terminal.
Always use the ESD kit (600T42001) when
•
handling PWBs. If one is not available, use
the following procedure.
Before handling any PWB, ground yourself
to an earth or building ground. Use a key
or paper clip in your hand to transfer the
charge from you to ground. Do this every
few minutes for prolonged work on PWBs.
Keep PWBs in the antistatic bags or
•
original packaging until ready to install
them.
Return or store the PWBs in the original
•
packaging, including antistatic bags.
When handling the PWBs, handle them by
•
their edges.
When handling integrated circuit chips,
•
handle them only by the body and never
by the leads (legs). If available, keep them
in antistatic foam until ready to install.
Never place the PWBs, integrated circuit
•
chips or components on a metal surface.
