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 lint-free cloth with a
solution of 80% electronics-grade isopropyl alcohol and 20% deionized water. This should be
performed at a static-safe workstation.
