Repair Considerations
Electrostatic Discharge
Electronic components and assemblies in the Agilent 53210A, 53220A, or
53230A Counters can be permanently degraded or damaged by
electrostatic discharge. Observe 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 remove an assembly or component from its static
shielding protection until you are ready to install it.
5 DO NOT handle components or assemblies in carpeted areas.
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. This paragraph is for information only.
The Agilent 53210A/53220A/53230A Counters are not intended for
customer repair of the printed circuit boards in these instruments.
Disassembly and Reassembly Specifics
Refer to Chapter 3, “Replacing Assemblies,” in this guide for complete
disassembly and reassembly details, and Chapter 5, “Replaceable Parts,”
for the appropriate part number of a failed instrument part.
