Preparing a Static-Safe Workstation
Electrostatic discharge (ESD) can damage or destroy electronic components. All works performed
on assemblies consisting of electronic components should be done at a static-safe workstation.
An example of a static-safe workstation is shown below using two types of ESD protection:
– conductive table mat and wrist strap combination, and
– conductive floor mat and heel strap combination
The methods may be used together or separately.
Reducing ESD damage
– To help reduce the amount of ESD damage that occurs during installation, testing, or servicing
instruments use the following guidelines:
– Be sure that all instruments are properly earth-grounded to prevent buildup of static charge.
– Personnel should be grounded with a resistor- isolated wrist- strap before touching the center
pin of any connector and before removing any assembly from the instrument.
– Before connecting any coaxial cable to an instrument connector for the first time each day,
momentarily ground the center and outer conductor of the table.
– Handle all PC board assemblies and electronic components only at static-safe workstations.
– Store or transport PC board assemblies and electronics components only in static-shielding
containers.
– PC board assembly edge-connector contacts may be cleaned by using a lintfree cloth with a
solution of 80% electronics-grade isopropyl alcohol and 20% deionized water. This should be
performed at a static-safe workstation.
