MAHR. THE APPLICATION SPECIALIST FOR ELECTRICAL ENGINEERING i Precision ensures that electricity can flow and power devices. Precision in the nanometer range and in the micrometer range such as in semi-conductors and printed circuit boards assures that there is electrical wiring and electric function can be performed. The electrical engineering industry mainly follows the trend of energy efficiency. The reduction of energy consumption applies to all devices such as washing machines dryers refrigerators dishwashers consumer electronics and mobile phones. In order to reduce the consumption of energy new materials are used friction in mechanical components reduced and controls optimized. The optimization of energy efficiency low noise and long life is the aim in electric motors. In addition to electronic commutation this leads to the reduction of imbalance in electric motor parts. Another trend is the miniaturization of devices and components. Examples are flatter laptops or mobile phones. This in turn implies a smaller size in electronic components and thinner multilayer printed circuit boards. Specifically the reduction of conductor widths and thicknesses as well as the reliable production of the vias are becoming more demanding. In the field of electronic components Moore's law in the meantime has led to 16 nm and soon it will be 10 nm in manufacturing processes. These very small structural sizes are not only a challenge in terms of technical process but also a measuring challenge. Even the counter-movement "More than Moore" with process modules such as MEMS high voltage image sensors or integrated memory has already reached structures with a size of up to 55 nm. New energy storage devices such as fuel cells or lithium-ion batteries also put new demands on dimensional metrology.
