Repair Considerations
Electrostatic Discharge
Electronic components and assemblies in the Agilent 53131A/132A/181A can be
permanently degraded or damaged by electrostatic discharge. Use the following
precautions when servicing the instrument:
1 ENSURE that static-sensitive devices or assemblies are serviced at static-safe
work stations providing proper grounding for service personnel.
2 ENSURE that static-sensitive devices or assemblies are stored in static shielding
bags or containers.
3 DO NOT wear clothing subject to static-charge buildup, such as wool or
synthetic materials.
4 DO NOT handle components or assemblies in carpeted areas.
5 DO NOT remove an assembly or component from its static shielding protection
until you are ready to install it.
6 AVOID touching component leads. (Handle by packaging only.)
Surface Mount Repair
Surface mount components should only be removed using soldering irons or
desoldering stations expressly designed for surface mount components. Use of
conventional solder removal equipment will almost always result in permanent
damage to the printed circuit board and will void your Agilent Technologies factory
warranty.
Disassembly and Reassembly Specifics
Refer to the Chapter 3, “Replacing Assemblies,” in this guide for complete
disassembly and reassemble details, and Chapter 5, “Replaceable Parts,” for the
appropriate exploded view of the instrument parts.
