Ultrasonic driving method

A method for driving a first component (11) into a second component (12) by superimposing a mechanical wave of ultrasonic frequency (18) onto the movement (17) of at least one of the components (11, 12). The method comprises a step of adjusting the paramet ...

New designs for submillimetric press-fitting

Jacques Jacot, Fabien Bourgeois, Ludovic Charvier

Press-fitting is a very common assembly process used in many fields, especially in the watchmaking industry. It consists of introducing a shaft in a hole (also called receptor) with a certain value of tightening (or interference). However, this process is ...

A decision making tool for reconfigurable assembly lines EUPASS project

Jacques Jacot, Sandra Koelemeijer Chollet

A decision making tool is proposed to evaluate assembly costs of micro-products (< 1 dm(3)) and to compare different assembly strategies for a given product or product family. The tool takes into account equipment costs as well as running costs, for manual ...

When manufacturing capability exceeds control capability: The paradox of high precision products, or is it possible to assemble functional products out of components we are unable to measure?

Jacques Jacot, Fabien Bourgeois, Sandra Koelemeijer Chollet

Sorting and mating is a very common practice in high precision manufacturing, as well in the watch industry, biomedical or automotive industry. This strategy helps to increase the assembly yield, but is costly and time-consuming. The question is, when is i ...

Laser Sealed Packaging for Microsystems

Jacques Jacot, Frank Seigneur

Packaging is the last process of microsystem manufacturing. There are mainly two kinds of packages: plastic or metallic. The two main components of the package (base and cover) may either be glued or soldered. Each of these techniques has its advantages an ...
