Growth into miniaturization - Flexible microassembly automation

The particular problems which occur during the assembly of miniaturized components result from their small dimensions, their high sensitivity to damage and the micron-range precision required in the assembly process. Examples are provided to illustrate strategies for flexible micro-assembly automation: the implementation of new, problem-oriented assembly techniques and components and the optimization of conventional handling systems. The accuracy attainable by an automated micro-assembly system depends decisively on the ability to compensate for inevitable handling tolerances. Active as well as passive techniques for compensating tolerances during micro-assembly have been examined and their operating limits will be described. The precision assembly of a modern radio-controlled wrist watch will serve as an example of developments in assembly modules.
