Disassembly/reassembly of FRUs
Electrostatic discharge (ESD) precautions
All external connectors of the monitor are designed with protection from ESD
damage. However if the monitor requires service, exposed components and
assemblies inside are susceptible to ESD damage. This includes human hands,
non-ESD protected work stations or improperly grounded test equipment.
The following guidelines may not guarantee a 100% static-free workstation, but
can greatly reduce the potential for failure of any electronic assemblies being
serviced:
 Discharge any static charge you may have built up before handling
assemblies containing semiconductors.
 A grounded, antistatic wristband (3M part number 2046 or equivalent) or
heel strap should be worn at all times while handling or repairing
assemblies containing semiconductors.
 Use properly grounded soldering and 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 assemblies from antistatic containers (Velo-stat bags) until
absolutely necessary.
 Make sure power to an assembly is turned off before removal.
 Do not slide electrical/electronic assemblies across any surface.
 Do not touch semiconductor leads unless absolutely necessary.
 Electronic assemblies should be stored only in antistatic bags or boxes.
 Handle all PCB assemblies by their edges.
 Do not flex or twist a circuit board.
