Fabrication of metallic microcomponents by electroforming

The complex geometry of microcomponents, which for example are used in a clock movement in the form of gears or escape wheels, can no longer be obtained without burring using standard mechanical processes. New processes, such as the Direct LIGA Process, allow the fabrication of such microcomponents, in which the microstructures are defi ned lithographically and deposited by electroplating.
