7-4 Patient Data Module 2030047-001A
Field Replaceable Units
The following guidelines may not guaranty 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
semiconductors or 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 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 a
semiconductor.
„
Do not slide semiconductors or electrical/electronic assemblies across any
surface.
„
Do not touch semiconductor leads unless absolutely necessary.
„
Semiconductors and 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.
Replacement procedures
Unless otherwise stated, reassemble the Patient Data Module in reverse order of
