is a significantly more complex world. This overarching term can be further split up into control technology, energy storage technology, consumer electronics and application technology. The most prominent building component in electrical engineering is the integrated circuit. It requires substantial knowledge, in order to be applied to, and successfully work on, electrical appliances. The problem lies with circuits, boards and steering elements, because they cannot be empirically operated. Contrary to the visible mechanical elements of a gearbox, in a piece of lifting equipment
or other arbitrary machines, comprehension of the inner processes of an electrical circuit are not possible merely through observation. This means that electrical engineering work should only be done by a specialist. The inner circuit is called the "board". This is an etched circuit board that is soldered onto condensers, resistors or LEDs. In the mass production of electrical technology, circuit board assembly machines are important. These machines are somewhat inconsistently labelled. Other machines
used for the manufacturing and assembly of circuit boards are wave soldering machines, THT machines or selective systems.
