Maintenance Information
Preventing ESD
6-2
Static discharge can damage
any
semiconductor component
in
this oscilloscope.
Precautions
When performing any service which requires internal access to the oscillo-
scope, adhere to the following precautions to avoid damaging internal
components due to electrostatic discharge
(ESD).
1. Minimize handling of static-sensitive parts.
2. Transport and store static-sensitive parts
in
their static protected con-
tainers or on a metal rail. Label any package that contains static-sensitive
parts.
3.
Discharge the static voltage from your body by wearing a grounded
antistatic wrist strap while handling these parts. Do service of static-
sensitive parts only at a static-free work station.
4.
Nothing capable of generating or holding a static charge should be
allowed on the work station surface.
5.
Handle circuit boards by the edges where possible.
6.
Do
not slide boards over any surface.
7. Avoid handling boards
in
areas that have a floor or work-surface cover-
ing capable of generating a static charge.
Susceptibility to
ESD
Table
6-1
lists the relative susceptibility of various classes of semiconduc-
tors. Static voltages of 1
kV
to 30
kV
are common in unprotected environ-
ments.
