Integrated circuits (logical circuits and microprocessors) are used in order to
implement a wide variety of functions in dental/X-ray/CEREC 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 thick-
nesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs leading out-
side of the unit via cables are sensitive to electrostatic discharge. Even volt-
ages which are imperceptible to the user can cause breakdown of the struc-
tures, thus leading to a discharge current which melts the chip in the affected
areas. Damage to individual integrated circuits may cause malfunction or fail-
ure of the system.
To prevent this from happening, the ESD warning label next to the plug warns
of this hazard.
