Static Handling
Static electricity is a familiar phenomenon which, except for an occasional shock,
doesn't seem very serious. However, it has been proven that in the electronics
industry electrostatic discharge (ESD) is a major cause of component failure. In
many cases, the component damaged may not immediately fail, causing low
instrument reliability and future repairs. ESD damage can occur at static levels
below human perception. It has also been shown that ESD can affect both passive
and active devices.
The following guidelines are the minimum requirements for a static safe service
environment.
— The work bench should be equipped with a conductive table mat. The mat
should be grounded to earth ground through a 1 M ohm resistor. The mat
should be equipped with at least one swivel connector for connecting wrist
straps.
— All service and handling personnel should wear a conductive wrist strap in
contact with bare skin. This strap should be connected to the swivel connector
on the conductive table mat through a 1 M ohm resistor.
— All metal equipment at a workstation must be grounded. This includes
soldering irons, solder removers, shelving, and equipment stands.
— Only one common ground should be provided at the workstation.
— The workstation should be kept free of nonconductors. No common plastics,
polybags, cardboard, cigarette or candy wrappers should be allowed. There
should not be rugs or carpet on the floor, shelving, or bench top.
— Only proper containers should be used for shipping, storing or transporting
assemblies. This is required on any assembly shipped to Keysight Technologies
for repair or replacement.
