Overview
Before Troubleshooting a Failure
Handling Electronic Components and ESD
The possibility of unseen damage caused by ESD is present whenever
components are transported, stored, or used. The risk of ESD damage
can be greatly reduced by close attention to how all components are
handled. Refer to the following guidelines when handling components:
• Perform work on all components at a static-safe workstation.
• Keep static-generating materials at least one meter away from all
components.
• Store or transport components in static-shielding containers.
CAUTION Always handle printed circuit board assemblies by the edges. This will
reduce the possibility of ESD damage to components and prevent
contamination of exposed plating.
Test Equipment Usage and ESD
• Before connecting any coaxial cable to an instrument connector for
the first time each day, momentarily short the center and outer
conductors of the cable together.
• Personnel should be grounded with a 1 MΩ resistor-isolated
wrist-strap before touching the center pin of any connector and
before removing any assembly from the instrument.
• Be sure that all instruments are properly earth-grounded to prevent
build-up of static charge.
