Integrated circuits (logical circuits and microprocessors) are used to
implement a wide variety of functions in dental/X-ray/CAD/CAM systems.
The circuits must be miniaturized to a very high degree in order to include
as many functions as possible on these chips. This leads to structure
thicknesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs leading
outside of the unit via cables are sensitive to electrostatic discharge.
Even voltages which are imperceptible to the user can cause breakdown
of the structures, thus leading to a discharge current which melts the chip
in the affected areas. Damage to individual integrated circuits may cause
malfunction or failure of the system.
To prevent this from happening, the ESD warning label next to the plug
warns of this hazard. ESD stands for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.
