172 Assembly-Level Service Guide

Electrostatic Discharge

CAUTION Electronic components and assemblies in the Agilent 53210A,

53220A, and 53230A Counters can be permanently degraded or

damaged by electrostatic discharge. Humans can accumulate

static electricity charges of several thousand volts on their skin or

clothes (harmless to them) but which can discharge through

sensitive semi-conductor circuits causing permanent damage. Use

the following precautions when installing or replacing

assemblies:

1 DO ensure that static-sensitive devices or assemblies are handled

only at a static-safe work station that provides proper grounding

for service personnel.

2 DO ensure that static-sensitive devices or assemblies are placed

or stored in static shielding bags or containers.

3 DO ensure that you are wearing a static-safe wristband that is

grounded to the mat and to earth ground.

4 DO NOT wear clothing subject to static-charge buildup, such as

wool or synthetic materials.

5 DO NOT remove an assembly or component from its static

shielding protection until you are ready to install it.

6 DO NOT handle components or assemblies in carpeted areas.

7 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 instrument is not intended to be

repaired by replacing individual components, only assemblies.
