1.1.1 Handling electrostatically sensitive modules
The modules produced by VIPA carry MOS-VLSI components. These components are highly
susceptible to high voltages that may be caused by electrostatic discharges.
These modules bear the following symbol to highlight the sensitive nature of the components:
This symbol is attached to the module, module carriers or on the packing material and indicates that
the module is sensitive to electrostatic discharge.
Modules that are sensitive to electrostatic discharges may be destroyed by energies and voltages that
lie far below the threshold of human perception. It is possible that damaging voltages may occur if a
person who has not been discharged handles a module that is electrostatically sensitive. The
resulting damages to the components will seriously impair the operation of the module or render it
unusable. Modules that have been damaged in this way are rarely recognized immediately. In many
cases the error becomes apparent only after the module has been operating for a while.
Components that have been damaged by an electrostatic discharge may exhibit temporary
malfunctions when they are subjected to temperature variations, shock or changes in electrical load.
The only effective method for the prevention of damages to modules that are sensitive to
electrostatic discharge is the use of protective gear and the strict adherence to the respective rules.
