Handling of electrostatic sensitive modules
ricos
FLEX modules make use of highly integrated components in MOS-Technology. These compo-
nents are extremely sensitive to over-voltages that can occur during electrostatic discharges. The
following symbol is attached to modules that can be destroyed by electrostatic discharges.
The Symbol is located on the module, the module rack or on packing material and it indicates the
presence of electrostatic sensitive equipment. It is possible that electrostatic sensitive equipment is
destroyed by energies and voltages that are far less than the human threshold of perception. These
voltages can occur where persons do not discharge themselves before handling electrostatic sensi-
tive modules and they can damage components thereby, causing the module to become inoperable
or unusable.
Modules that have been damaged by electrostatic discharges can fail after a temperature change,
mechanical shock or changes in the electrical load. Only the consequent implementation of protec-
tion devices and meticulous attention to the applicable rules and regulations for handling the re-
spective equipment can prevent failures of electrostatic sensitive modules.
Shipping of modules
Modules must be shipped in the original packing material.
Measurements and alterations on electrostatic sensitive modules
When you are conducting measurements on electrostatic sensitive modules you should take the fol-
lowing precautions:
Floating instruments must be discharged before use.
Instruments must be grounded.
Modifying electrostatic sensitive modules you should only use soldering irons with grounded tips.
Personnel and instruments should be grounded when working on electrostatic sensitive modules.
