1 Introduction
1.1 Safety and handling precautions for the user
1.1.1 Handling electrostatically sensitive modules
VIPA building blocks are equipped with highly integrated components in MOS-technology. These
components are highly sensitive to excess voltage, which can for example result from electrostatic
discharge.
Building blocks at risk are characterized by the following symbol:
The symbol is to be found on building blocks, building block carriers or on the packaging and
indicate building blocks liable to electrostatic danger.
Building blocks liable to electrostatic danger can be destroyed by energies or voltage, which lie far
below the human’s point of perception. If a person, who is not electrically discharged, handles
building blocks liable to electrostatic danger, such voltages may occur, leading to damage of
components and therefore reducing the functionability of the building blocks or rendering them
completely useless. Only a very small percentage of such damaged building blocks will be
immediately recognized as faulty. The fault may first become apparent after being in operation for a
longer period of time.
Due to static discharge, damaged components can develop a temporary fault by changes in
temperature, vibrations or a change in load.
Functional interferences and failures can only be effectively prevented by a consistent employment
of protective devices and a responsible compliance with the handling regulations.
