Maintenance: Controlling Electrostatic Discharge Damage
Controlling Electrostatic Discharge Damage
All external connector inputs and outputs of the device are designed with protection
from Electrostatic Discharge Damage (ESD) damage. However, if the interior of the
device needs to be accessed for any reason, internal components and assemblies are
susceptible to ESD damage. This includes human hands, non-ESD protected work
stations and/or improperly grounded test equipment.
The following guidelines help make a service workstation more resistant to the ESD
damage:
„
Discharge any static charge you may have built up before handling
semiconductors or assemblies containing semiconductors. This can be done by
touching any bare metal on the ApexPro Telemetry Server chassis, or cable
connector jacks on the back of the unit. Do this frequently and repeatedly while
working on the unit.
„
Wear a grounded, antistatic wristband (3M part number 2046 or equivalent) or
heel strap at all times while handling or repairing assemblies containing
semiconductors.
„
Use properly grounded test equipment.
„
Use a static-free work surface (3M part number 8210 or equivalent) while
handling or working on assemblies containing semiconductors.
„
Do NOT remove semiconductors or assemblies containing semiconductors
from antistatic containers (Velo-stat bags) until absolutely necessary.
„
Make sure power to an assembly is turned off before removing or inserting any
component boards.
„
Do NOT slide semiconductors or electrical/electronic assemblies across any
surface.
„
Do NOT touch semiconductor leads unless absolutely necessary.
„
Semiconductors and electrical/electronic assemblies should be stored only in
antistatic bags or boxes.
These guidelines cannot guaranty a 100% static-free workstation, but greatly reduce
the potential for failure of any electrical/electronic assemblies due to electrostatic
discharge.
