For controlling and regulating complex operations, for example, in mobile work machines and motor vehicles, electronic sub-assemblies with high performance and computing power are demanded.

Also under extreme conditions, like mechanical wearing, high temperature fluctuations, humidity and dirt, or with electrical malfunctions, the absolute reliability of these devices must be guaranteed.

In order to cope with all these challenges in the daily use, in the drafting and developing phase the requirements for an extended temperature range and shock resistence as well as dirt resistence are already taken into consideration.
